Modern scientific research indicates that early childhood trauma, especially during the first two years of life when the brain is still rapidly developing, produces permanent adverse physical changes in brain development.
Although we know of no research specific to circumcision trauma causing brain damage, we include some of the related research that is applicable. Genital trauma cannot be different from trauma to other parts of the body in its potential to cause brain damage.
This page brings together articles that relate in some way to the risk of possible brain damage due to traumatic non-therapeutic circumcision. Articles are arranged in approximate chronological order of publication.

The Coalition for Improving Maternity Services (CIMS) is concerned about the dramatic increase and ongoing overuse of cesarean section. Since 1983, one in five women or more has given birth by this major abdominal surgery. Today, one in four or 25% of women have a cesarean for the birth of their baby. The rate for first-time mothers may approach one in three. Studies show that the cesarean rate could safely be halved. The World Health Organization recommends no more than a 15% cesarean rate. With a million women having cesarean sections every year, this means that 400,000 to 500,000 of them were unnecessary.
No evidence supports the idea that cesareans are as safe as vaginal birth for mother or baby. In fact, the increase in cesarean births risks the health and well being of childbearing women and their babies.
For elective repeat cesarean, the consensus of dozens of studies totaling tens of thousands of women is that elective repeat cesarean section is riskier for the mother and not any safer for the baby. Recent studies used to conclude otherwise are both seriously flawed and have been misrepresented in the media.
In addition to the hazards of cesarean section per se, the risks of certain complications increase with accumulating surgeries. Studies also show that seven out of ten women or more who are allowed to labor without undue restrictions will give birth vaginally, thus ending their exposure to the dangers of cesarean section.

In addition to the hazards of cesarean section per se, the risks of certain complications increase with accumulating surgeries. Studies also show that seven out of ten women or more who are allowed to labor without undue restrictions will give birth vaginally, thus ending their exposure to the dangers of cesarean section.
Hazards of Cesarean Section to the Mother
- Women run 5 to 7 times the risk of death with cesarean section. ·Complications during and after the surgery include surgical injury to the bladder, uterus and blood vessels (2 per 100), hemorrhage (1 to 6 women per 100 require a blood transfusion), anesthesia accidents, blood clots in the legs (6 to 20 per 1000), pulmonary embolism (1 to 2 per 1000), paralyzed bowel (10 to 20 per 100 mild cases, 1 in 100 severe), and infection (up to 50 times more common).
- One in ten women report difficulties with normal activities two months after the birth, and one in four report pain at the incision site as a major problem. One in fourteen still report incisional pain six months or more after delivery.
- Twice as many women require rehospitalization as women having normal vaginal birth.
- Especially with unplanned cesarean section, women are more likely to experience negative emotions, including lower self-esteem, a sense of failure, loss of control, and disappointment. They may develop postpartum depression or post-traumatic stress syndrome. Some mothers express dominant feelings of fear and anxiety about their cesarean as long as five years later.
- Women having cesarean sections are less likely to decide to become pregnant again.
- Long-term risks of cesarean section include pelvic pain, pain during sexual intercourse, and bowel problems.
- Reproductive consequences compared with vaginal birth include increased infertility, miscarriage,placenta previa (placenta overlays the cervix), placental abruption (the placenta detaches partially or completely before the birth),and premature birth. Even in women planning repeat cesarean, uterine rupture occurs at a rate of 1 in 500 versus 1 in 10,000 in women with no uterine scar.
- Studies comparing elective cesarean section with vaginal birth or cesarean section for reasons unrelated to the baby find that babies are 50% more likely to have low Apgar scores, 5 times more likely to require assistance with breathing, and 4 times more likely to be admitted to intensive care for breathing difficulties.
- One to two babies per 100 will be cut during the surgery.
- Some babies will inadvertently be delivered prematurely. Babies born even slightly before they are ready may experience breathing and breastfeeding problems.
- Babies born after elective cesarean section are more than four times as likely to develop persistent pulmonary hypertension compared with babies born vaginally. Persistent pulmonary hypertension is life threatening.
- Mothers who have cesareans are more likely to have difficulties forming an attachment with the infant. This may be because women are less likely to hold and breastfeed their infants after birth and have rooming-in, and because of the difficulties of caring for an infant while recovering from major surgery.
- Cesarean born babies are less likely to be breastfed. The adverse health consequences of formula feeding are numerous and can be severe.
- Elective cesarean section carries twice the risk of maternal death compared with vaginal birth.
- Old scar tissue increases the likelihood of surgical injury.
- One more woman in every 100 with a history of more than one cesarean will have an ectopic pregnancy (embryo implants outside the womb); hemorrhage associated with ectopic pregnancy is one of the leading causes of maternal death in the US.
- Compared with women with no uterine scar, women have more than 4 times the risk of placenta previa with one prior cesarean, 7 times the risk with two to three prior cesareans, and 45 times the risk with four or more prior cesareans.
- Compared with women with prior births and no previous cesareans, women with one prior cesarean or more have greater than 4 times the risk of placental abruption. About half of maternal deaths due to hemorrhage involve placenta previa or placental abruption.
- The odds of placenta accreta (placenta grows into or even through the uterus) jump from 1 in 1,000 with one prior cesarean to 1 in 100 with more than one prior cesarean. Nearly all women with this complication will require a hysterectomy, nearly half will have a massive hemorrhage, and 1 in 11 babies and 1 in 14 mothers will die. The incidence of placenta accreta has increased 10-fold in the last 50 years and now occurs in 1 in 2,500 births.
- Women having elective repeat cesareans are more likely to experience hemorrhage requiring transfusion, blood clots, and infection compared with women planning vaginal birth.
- Postpartum recovery after repeat cesarean section is even more difficult when there is another child or children to care for.

Problems and Hazards of Induction of Labor 11/23/2009

The Coalition for Improving Maternity Services (CIMS) is concerned about the dramatic increase and ongoing overuse of induction of labor. The U.S. induction rate has more than doubled since 1989, rising from one woman in ten to one woman in five in 2001. This may, however, grossly undercount the true incidence of labor induction. Nearly half of women in a 2002 survey reported that some effort had been made to start labor artificially. The World Health Organization recommends no more than a 10 percent induction rate. Despite modern techniques, induction of labor still introduces considerable risk compared with natural onset of labor, and many, if not most, inductions are done for reasons that are not supported by sound medical research.
HAZARDS OF LABOR INDUCTION
HAZARDS AND PROBLEMS OF INDUCTION AGENTS
Cytotec (Misoprostol)
Prostaglandin E2 (Prepidil, Cervidil)Oxytocin (Pitocin)
MEDICAL RESEARCH FAILS TO SUPPORT COMMON INDUCTION RATIONALES
HAZARDS OF LABOR INDUCTION
- First-time mothers have approximately twice the likelihood of cesarean section with induction compared with natural onset of labor. This risk is due to the procedure itself, not any reason that might have led to inducing labor. Inducing labor at 41 weeks in a hypothetical population of 100,000 first- time mothers will result in somewhere between 3,700 and 8,200 excess cesareans and cost an extra $29 to $39 million.
- Women who have had prior vaginal births may increase their chances of cesarean section five-fold if the cervix is not ready for labor, and they are given cervical ripening agents. Inducing 100,000 hypothetical women with prior births at 41 weeks will result in between 100 and 2,300 excess cesareans and cost an extra $25 to $26 million.
- All induction agents can cause uterine hyperstimulation (contractions too long, too strong, and too close together and higher baseline muscle tension). Uterine hyperstimulation can cause fetal distress. This means that, paradoxically, inducing labor because of concern over the baby’s condition may cause the very problem the induction was intended to forestall while the baby might have tolerated natural labor.
- Induction of labor involves the need for other interventions—IV drip, continuous electronic fetal monitoring, usually confinement to bed—that also can have adverse effects.
- Rupturing fetal membranes, a routine component of labor induction, can cause fetal distress and increases the likelihood of cesarean section. It may also precipitate umbilical cord prolapse (a life-threatening emergency for the baby in which the umbilical cord slips down into the vagina). Forty percent of all full term births involving cord prolapse were induced labors, rising to nearly 50% of births involving prolapse at 42 weeks or more.
Induced labors are usually more painful, which can increase the need for epidural analgesia. Epidurals introduce a higher probability of a host of adverse effects on the labor, the baby, and the mother. Women with prior cesarean sections have a slightly increased probability of the scar giving way with Pitocin (oxytocin) induction (8 per 1,000 vs 5 per 1,000 with spontaneous labor onset) and greatly increased risk when prostaglandins (24 per 1,000) are used for cervical ripening or induction. Prostaglandins include Cytotec (misoprostol), Prepidil (prostaglandin E2), and Cervidil (prostaglandin E2).
Cytotec (Misoprostol)
- Cytotec, although widely used as an induction agent, is neither formulated nor intended for use in labor. Cytotec’s manufacturer, Searle, has repudiated its off-label use as an induction/cervical ripening agent because of Cytotec’s attendant risks.
The FDA states that Cytotec’s major adverse effects include uterine hyperstimulation, which can become severe and result in profound fetal distress; uterine rupture; amniotic fluid embolism, which has a high maternal and infant mortality rate; severe genital bleeding; shock; fetal death; and maternal death. Other adverse effects include retained placenta, cesarean section, and passage of meconium (the baby’s first stool) into the amniotic fluid, which can cause a type of newborn pneumonia if inhaled. Cytotec is commonly believed to pose a life-threatening risk only in women with a uterine scar or with high doses. However, cases of maternal and infant death and hemorrhage requiring hysterectomy have been reported in women with no uterine scar, some of whom were given a minimal dose. Cytotec dosage cannot be controlled because the drug is a small pill that must be cut in pieces. Once given, the drug cannot be rescinded or the dosage reduced in case of adverse effects. Cytotec does not decrease cesarean rates compared with prostaglandin E2, which is FDA-approved for use in labor. Cytotec’s only advantages compared with prostaglandin E2 are much reduced cost and faster labors. Both benefit only hospitals and doctors as short labors are usually intense, tumultuous, and difficult.
- Prostaglandin E2 can cause uterine hyperstimulation and fetal distress. Fetal distress can require cesarean section.
- Prostaglandin E2 does not reduce excess cesareans associated with labor induction.
- Unless the drug is formulated in a tampon (Cervidil), the drug cannot be rescinded or the dosage reduced in case of adverse effects.
- Complications of oxytocin (Pitocin) include uterine hyperstimulation, which can lead to fetal distress; twice the chance of the baby being born in poor condition; postpartum hemorrhage; and greater probability of newborn jaundice. Rare, severe, maternal complications include uterine rupture and water intoxication leading to coma and death. Oxytocin may also cause brain damage or death in the baby.
- Elective induction of labor, that is, induction for nonmedical reasons such as convenience, exposes babies and mothers to the hazards of induction with no counterbalancing benefit.
- Inducing labor for suspected big baby produces no benefits but increases the likelihood of cesarean section.
- No credible evidence supports inducing labor in women with gestational—as opposed to pre- existing --diabetes.
- Routinely inducing labor for prelabor rupture of membranes does not reduce the incidence of newborn infection with the exception of women testing positive for Group B strep who do not receive IV antibiotics during labor.
- Inducing labor in women with Group B strep has not been shown to improve outcomes when antibiotics are given regardless of membrane status and is not part of the Centers for Disease Control recommended guidelines.
- Studies claiming to support routine induction of labor at 41 weeks of pregnancy have serious flaws. No research supports routine induction at any earlier point in pregnancy; no sound research supports routine induction at any point in pregnancy.
- Proponents of inducing labor at full-term argue that the stillbirth rate and the rates of other newborn complications increase markedly after that date, but, in fact, these rates show no such increase. Induction at 41 weeks in a hypothetical population of 100,000 first-time mothers would theoretically prevent 120 fetal deaths that would statistically occur in the ensuing week, but:
routine induction in that they were unpredictable events in healthy mothers carrying healthy, normally formed babies.We don’t know how many of those deaths would actually be prevented by That number would be offset by some babies dying as a result of the hazards of induction. Any decrease in fetal deaths would be outweighed by the infertility, miscarriage, and fetal and newborn losses consequent to the excess cesareans.
- Forty-one weeks is the median length of pregnancy in healthy first-time mothers. This means that one- half of such pregnancies will last longer than 41 weeks.
- If there is no reason to curtail the natural length of pregnancy, then there is no reason for measures such as stripping or sweeping membranes, which themselves introduce the possibility of risk.

Breastmilk component kills cancer cells
http://www.infactcanada.ca/milkkillscancer.htm
A few years ago immunology student, Anders Hakansson1, of Lund University, Sweden, was experimenting by mixing human milk, cancer cells and bacteria. To his surprise the cancer cells were "acting up". Their volume was decreasing and their nuclei shrinking. Hakansson's supervisor, Catharina Svanborg, quickly recognized that the cancer cells were committing suicide. The phenomenon of apoptosis, whereby the body rids itself of old and unnecessary cells was well known, however for this to occur with cancer cells was unknown as their usual pattern is to reproduce in an uncontrolled fashion. Something in the breastmilk caused the cancer cells to self-destruct. Svanborg and her team had already done extensive investigation in the ability of breastmilk to protect the gut lining from invasive bacteria such as pneumococcus that causes the increased rates of upper respiratory tract infections and otitis media in children not breastfed. And so they began to track down the cancer-killing component in breastmilk. Then in 1995 they reported2 that the protein alpha-lactalbumin, or alpha-lac for short, was capable of targeting not only cancer cells but also other immature and rapidly growing cells, leaving stable, mature cells for growth and development. Alpha-lac's amazing capabilities may explain in part why formula fed infants suffer from increased rates of infectious diseases as well as childhood cancers.

Breastmilk prevents childhood diabetes
http://www.drmirkin.com/diabetes/D216.htm
At the scientific session of the American Diabetic Association meeting in San Diego, Finnish researchers presented evidence that juvenile diabetes may be caused by genetically susceptible children taking cow's milk in the first 6 months of life.
When a germ gets into your bloodstream, your immune system makes proteins called antibodies that attach to and kill that germ. Unfortunately, your immune system makes antibodies against almost all proteins that get into your bloodstream. Adults are protected from making antibodies against proteins in food because they have intact intestines that do not allow whole proteins to pass into their blood streams, but in the first few months of life, infants have holes in their intestines that allow proteins to pass into their bloodstream.
The Finnish researchers showed that cow's milk contains cow insulin that is similar, but not exactly the same as, human insulin. So when cow's milk is taken by infants in the first three months of life, the cow insulin can pass into their blood streams and those genetically susceptible to diabetes develop antibodies that attach to and kill the beta cells of the pancreas that make insulin, causing permanent loss of insulin and diabetes. Other studies show that almost all mothers in Puerto Rico feed cow's milk to their infants. In Cuba, almost all mothers feed from their breasts. Type I diabetes is ten times more common in Puerto Rico than in Cuba. On the basis of this and much other research, those of you who have a family history of diabetes should try to feed your infant from your breast.
*Among infants with family history of juvenile diabetes, those on cow's milk have a much higher incidence of diabetes than those on breast milk.
*Among animals bred to develop diabetes, infant animals given cow's milk have a much higher incidence of diabetes.
*Human babies with antibodies against cow's insulin have a much higher incidence of diabetes.(this study)
*In Puerto Rico, almost all babies get cow's milk. In Cuba, almost all babies are breast fed. Puerto Rican babies are more than 10 times more likely to suffer juvenile diabetes.

Some of the molecules and cells in human milk
actively help infants stave off infection
By Jack Newman, MD, FRCPC
Doctors have long known that infants who are breast-fed contract fewer infections than do those who are given formula. Until fairly recently, most physicians presumed that breast-fed children fared better simply because milk supplied directly from the breast is free of bacteria. Formula, which must often be mixed with water and placed in bottles, can become contaminated easily. Yet even infants who receive sterilized formula suffer from more meningitis and infection of the gut, ear, respiratory tract and urinary tract than do breast-fed youngsters. Read More...

We are receiving more and more reports from mothers of a decrease in milk production associated with the Mirena IUD. Today I received two such reports. Given the constant chronological relationship between the placement of the IUD and the mother’s decrease in milk production (1 to 2 weeks), it is quite possible that the decrease in milk production is a result of the IUD.
Of course, it is also likely that not all women will have a significant decrease; nobody contacts me when they don’t have a decreased production. But it is also likely that only a tiny percentage of women who do have a decrease actually contact me.
I think we need to be prudent and warn women about this possible side effect of the Mirena. All hormonal contraceptive methods should be avoided by breastfeeding mothers if possible.
Please forward to all your contacts.

A one-minute introduction to babywearing created for Babywearing International, Inc., a nonprofit organization, by Leo Ticheli Productions of Birmingham, AL, in celebration of International Babywearing Week 2009, September 21-28.
THE BENEFITS OF BABYWEARING
by William Sears, MD and Martha Sears, RN.
http://www.askdrsears.com
1. Sling babies cry less. Parents in my practice commonly report, "As long as I wear her, she's content!" Parents of fussy babies who try babywearing relate that their babies seem to forget to fuss. This is more than just my own impression. In 1986, a team of pediatricians in Montreal reported on a study of ninety-nine mother-infant pairs. The first group of parents were provided with a baby carrier and assigned to carry their babies for at least three extra hours a day. They were encouraged to carry their infants throughout the day, regardless of the state of the infant, not just in response to crying or fussing. In the control, or noncarried group, parents were not given any specific instructions about carrying. After six weeks, the infants who received supplemental carrying cried and fussed 43 percent less than the noncarried group.
Anthropologists who travel throughout the world studying infant-care practices in other cultures agree that infants in babywearing cultures cry much less. In Western culture we measure a baby's crying in hours, but in other cultures, crying is measured in minutes. We have been led to believe that it is "normal" for babies to cry a lot, but in other cultures this is not accepted as the norm. In these cultures, babies are normally "up" in arms and are put down only to sleep – next to the mother. When the parent must attend to her own needs, the baby is in someone else's arms.
2. Sling babies learn more. If infants spend less time crying and fussing, what do they do with the free time? They learn! Sling babies spend more time in the state of quiet alertness . This is the behavioral state in which an infant is most content and best able to interact with his environment. It may be called the optimal state of learning for a baby. Researchers have also reported that carried babies show enhanced visual and auditory alertness.
The behavioral state of quiet alertness also gives parents a better opportunity to interact with their baby. Notice how mother and baby position their faces in order to achieve this optimal visually interactive plane. The human face, especially in this position, is a potent stimulator for interpersonal bonding. In the kangaroo carry, baby has a 180-degree view of her environment and is able to scan her world. She learns to choose, picking out what she wishes to look at and shutting out what she doesn't. This ability to make choices enhances learning. A sling baby learns a lot in the arms of a busy caregiver.
3. Sling babies are more organized. It's easier to understand babywearing when you think of a baby's gestation as lasting eighteen months – nine months inside the womb and at least nine more months outside. The womb environment automatically regulates baby's systems. Birth temporarily disrupts this organization. The more quickly, however, baby gets outside help with organizing these systems, the more easily he adapts to the puzzle of life outside the womb. By extending the womb experience, the babywearing mother (and father) provides an external regulating system that balances the irregular and disorganized tendencies of the baby. Picture how these regulating systems work. Mother's rhythmic walk, for example, (which baby has been feeling for nine months) reminds baby of the womb experience. This familiar rhythm, imprinted on baby's mind in the womb, now reappears in the "outside womb" and calms baby. As baby places her ear against her mother's chest, mother's heartbeat, beautifully regular and familiar, reminds baby of the sounds of the womb. As another biological regulator, baby senses mother's rhythmic breathing while worn tummy- to-tummy, chest-to-chest. Simply stated, regular parental rhythms have a balancing effect on the infant's irregular rhythms. Babywearing "reminds" the baby of and continues the motion and balance he enjoyed in the womb.
What may happen if the baby spends most of his time lying horizontally in a crib, attended to only for feeding and comforting, and then again separated from mother? A newborn has an inherent urge to become organized, to fit into his or her new environment. If left to his own resources, without the regulating presence of the mother, the infant may develop disorganized patterns of behavior: colicky cries, jerky movements, disorganized self-rocking behaviors, anxious thumb sucking, irregular breathing, and disturbed sleep. The infant, who is forced to self-calm, wastes valuable energy he could have used to grow and develop.
While there is a variety of child-rearing theories, attachment researchers all agree on one thing: In order for a baby's emotional, intellectual, and physiological systems to function optimally, the continued presence of the mother, as during babywearing, is a necessary regulatory influence.
4. Sling babies get "humanized" earlier. Another reason that babywearing enhances learning is that baby is intimately involved in the caregiver's world. Baby sees what mother or father sees, hears what they hear, and in some ways feels what they feel. Carried babies become more aware of their parents' faces, walking rhythms, and scents. Baby becomes aware of, and learns from, all the subtle facial expressions, body language, voice inflections and tones, breathing patterns, and emotions of the caregiver. A parent will relate to the baby a lot more often, because baby is sitting right under her nose. Proximity increases interaction, and baby can constantly be learning how to be human. Carried babies are intimately involved in their parents' world because they participate in what mother and father are doing. A baby worn while a parent washes dishes, for example, hears, smells, sees, and experiences in depth the adult world. He is more exposed to and involved in what is going on around him. Baby learns much in the arms of a busy person.
5. Sling babies are smarter. Environmental experiences stimulate nerves to branch out and connect with other nerves, which helps the brain grow and develop. Babywearing helps the infant's developing brain make the right connections. Because baby is intimately involved in the mother and father's world, she is exposed to, and participates in, the environmental stimuli that mother selects and is protected from those stimuli that bombard or overload her developing nervous system. She so intimately participates in what mother is doing that her developing brain stores a myriad of experiences, called patterns of behavior. These experiences can be thought of as thousands of tiny short-run movies that are filed in the infant's neurological library to be rerun when baby is exposed to a similar situation that reminds her of the making of the original "movie." For example, mothers often tell me, "As soon as I pick up the sling and put it on, my baby lights up and raises his arms as if in anticipation that he will soon be in my arms and in my world."
I have noticed that sling babies seem more attentive, clicking into adult conversations as if they were part of it. Babywearing enhances speech development. Because baby is up at voice and eye level, he is more involved in conversations. He learns a valuable speech lesson – the ability to listen.
Normal ambient sounds, such as the noises of daily activities, may either have learning value for the infant or disturb him. If baby is alone, sounds may frighten him. If baby is worn, these sounds have learning value. The mother filters out what she perceives as unsuitable for the baby and gives the infant an "It's okay" feeling when he is exposed to unfamiliar sounds and experiences.

1. Sling babies cry less. Parents in my practice commonly report, "As long as I wear her, she's content!" Parents of fussy babies who try babywearing relate that their babies seem to forget to fuss. This is more than just my own impression. In 1986, a team of pediatricians in Montreal reported on a study of ninety-nine mother-infant pairs. The first group of parents were provided with a baby carrier and assigned to carry their babies for at least three extra hours a day. They were encouraged to carry their infants throughout the day, regardless of the state of the infant, not just in response to crying or fussing. In the control, or noncarried group, parents were not given any specific instructions about carrying. After six weeks, the infants who received supplemental carrying cried and fussed 43 percent less than the noncarried group.
Anthropologists who travel throughout the world studying infant-care practices in other cultures agree that infants in babywearing cultures cry much less. In Western culture we measure a baby's crying in hours, but in other cultures, crying is measured in minutes. We have been led to believe that it is "normal" for babies to cry a lot, but in other cultures this is not accepted as the norm. In these cultures, babies are normally "up" in arms and are put down only to sleep – next to the mother. When the parent must attend to her own needs, the baby is in someone else's arms.
2. Sling babies learn more. If infants spend less time crying and fussing, what do they do with the free time? They learn! Sling babies spend more time in the state of quiet alertness . This is the behavioral state in which an infant is most content and best able to interact with his environment. It may be called the optimal state of learning for a baby. Researchers have also reported that carried babies show enhanced visual and auditory alertness.
The behavioral state of quiet alertness also gives parents a better opportunity to interact with their baby. Notice how mother and baby position their faces in order to achieve this optimal visually interactive plane. The human face, especially in this position, is a potent stimulator for interpersonal bonding. In the kangaroo carry, baby has a 180-degree view of her environment and is able to scan her world.

Shots In The Dark Documentary 09/15/2009

Shots in the Dark, a documentary produced by the National Film Board of Canada, as of yet unreleased, because Stephen Harper does not want you to see this!
The delicate subject of vaccinations and its dangers is approached in a very revealing documentary film. Scientists, doctors, patients, and parents from Canada, France and the US all get their say.
Perhaps this film is the reason why the arts in Canada had their budget slashed in the last years by the Conservative government.
It was NEVER released or published.

Relactation 09/09/2009

Relactation is rebuilding a birth mother's milk supply after it has been reduced or dried up.
In one survey of 366 women who relactated, most reported not being as concerned with the amount of milk they produced as they were with having the opportunity to nurture their baby through breastfeeding. Although some mothers made the decision to relactate based on their baby's intolerance of formula, most did so because of the effect breastfeeding would have on their relationship with their baby. In hindsight, 75 percent of the women surveyed felt relactation had been a positive experience and the amount of milk they produced had been unrelated to their feelings of success.
In this survey, more than half the mothers established a full milk supply within a month. It took another 25 percent of the mothers to fully relactate. The remaining mothers both breastfed and bottle fed until the baby was weaned. Mothers who attempted relactation within two months of childbirth reported greater milk production than those who attempted it later on. Many women have found the length of time it takes to relactate fully (completely meeting the baby's needs) is about equal to how long it has been since breastfeeding was discontinued. Several weeks is a realistic expectation for most mothers.
When used in combination with frequent nursing and/or milk expression, certain medications have been found to increase mother's milk supply. One of the most commonly used is metoclopramide (Reglan), which when given at 10 mg doses three times per day for seven to fourteen days has been found to increase milk production an average of 110 percent in mothers with one month old babies. When the metoclopramide is discontinued, milk supply may drop, but not usually to the level it was before treatment.
Some babies switch to the breast easily; others need lots of encouragement. In the aforementioned survey, 39 percent of the women queried reported that their baby nursed well on the first attempt, 32 percent said their babies were ambivalent about breastfeeding, and 28 percent refused the breast. But within a week, 54 percent of the babies had taken the breast well, and by ten days the number rose to 74 percent. Although babies younger than three months and those who had previously breastfed tended to be more willing, the most crucial factors were time, patience and persistence.
In another report six children between twelve and forty-eight months who had been weaned for up to six months stimulated their mothers to at least partially relactate through sucking alone.
A nursing supplementer can help avoid nipple confusion and stimlate the mother's milk supply at the same time. If a mother's milk supply is very low, the nursing supplementer will offer a baby instant reward at the breast. In order to avoid the baby becoming overly dependent upon the supplementer, suggest the mother try using the supplementer on one breast only and after the baby's initial hunger has been satisfied switiching to the breast without the supplementer. -La Leche League International, excerpted from "The Breastfeeding Answer Book," 1997.

Why do/did you have foreskin?
The foreskin occupies a prominent position on an important organ. The foreskins location and structure indicate that it is the most important sensory tissue of the penis. Its persistence over millions of years suggests that it has played a role in the propagation of the species.
A well-integrated organ
Structurally, the penis is highly integrated. The glans, foreskin and skin of the penile shaft function as a single unit, not as a collection of separate parts with entirely different functions. The functions of the glans and foreskin are similar, and overlapping, but come fully into their own at different times during intercourse.
Simple sensations
The outer surface of the foreskin is specialized to detect feather-light touch and other sensations, including painful ones. The infamous zipper injury is an extreme example of the sort of damage the outer skin was designed to detect and prevent, long before the zipper posed a threat to the uninitiated.
Compared with the true (outer) skin of the foreskin, the glans is only feebly sensitive to light touch, pain, heat and cold. This is part of the reason we call the foreskin the primary sensory tissue of the penis. Without the foreskin, the end of the penis is numb to a host of sensations that tell the owner whether one of his most prized organs is in good company, or should move to safety.
Complex sensations
Thanks to its ridged band, the inner lining of the foreskin is specialized sexual tissue. The ridged band readily expands and contracts and is obviously designed to detect stretching forces. When penile shaft skin tugs on the ridged band, special genital corpuscles in the peaks of the ridges detect movement and trigger ejaculation. Stretching of the ridged band may also trigger and sustain erection.
Electrical stimulation of the glans triggers nerve impulses that pass to the spinal cord and then to the muscle of ejaculation. Clearly the glans has much in common with the foreskin. Where foreskin and glans part company, functionally as well as physically, is in their sensitivity to light touch, pain and heat and cold. Contrary to common opinion, the glans is not highly sensitive to a broad range of stimuli.
Foreskin vs. glans
It is unclear whether the ridged band simply plays backup for the glans, or whether the two have different functions. The location of the retracted ridged band on the erect penile shaft suggests that the difference is one of timing. Possibly, the foreskin and its ridged band are designed to ensure that sexual reflexes are triggered when, and only when, these structures are stretched during intercourse. The biological importance of the ridged band to conception is self-evident, but there is still a major gap in our understanding of the relation between form and function of the penis.
Dartos muscle
Penile skin has two important characteristics, apparent only on erection. Firstly penile skin tenses, stiffens and shortens, firming up the connection between shaft skin and ridged band. This change allows for the transmission of movement from the base of the erect penis to the ridged band.
Secondly, penile skin undergoes a marked frictional change, brought about by stiff, forward-pointing skin folds. The mechanism is similar to that which raises goosebumps.
The changes in penile skin are brought about by contraction of the Dartos muscle. Between them, stiffening and frictionality ensure that the ridged band is instantly alerted to changes in position of the penis within the vagina.
Why two layers?
The double-layering of the foreskin allows the delicate ridged band, which normally is safely hidden from view, to be deployed on the upper surface of the penile shaft during erection. There it stands a better chance of being activated. Double-layering also eases vaginal entry by offsetting the frictional resistance of erect shaft skin.
Summary
The various parts of the penis, including the foreskin, form a functional whole. The foreskin is the primary sensory tissue of the penis. The ridged band of the foreskin is built to trigger orgasm and ejaculation.
