Oversupply, forceful let-down, foremilk/hindmilk imbalance … all of these strike fear in the heart of new mothers because they translate to an inconsolable, visibly uncomfortable, crying baby. He may want to nurse all the time, because the sucking behavior soothes him when his tummy hurts, but the more he nurses, the more miserable he becomes. There may be blood in his diapers, maybe he chokes when he starts breastfeeding, or he spits up a lot after every feeding. You’re desperate for a solution that won’t threaten your milk production, because you really want to continue breastfeeding your baby – but your baby doesn’t seem to “like breastfeeding” and you’re feeling rejected and discouraged. What causes this constellation of circumstances? There is a lot of information out there about oversupply, overactive milk-ejection reflex (OAMER), and what has been called foremilk/hindmilk imbalance. I will do my best to help you understand WHY your breasts are so eager, WHY this is so irritating to your sweet baby, and offer you some resources for how to find the solution that works for you and your baby.
First, it is very important that you ensure your breastfeeding management is optimal and you are “watching baby, not the clock.” Some mothers unintentionally create an overproduction of breastmilk when they, perhaps out of concern that they’ll make enough milk, or maybe to make bottles so grandma and daddy can feed the baby, pump or express more milk than their babies are actually taking. Most mothers, if feeding on demand and not by a schedule, and not over-stimulating milk production, will make the milk their babies need. Hormonal imbalances are another reason for overproduction of milk; if you have a history of PCOS, you may be susceptible to oversupply. Postpartum thyroid issues can also have an effect on milk production. Be sure to rule out medical causes of hyperlactation first.
You may have been told that your baby is fussy, has a skin rash, is gassy, spits up, has diaper rash, a red ring around his anus, or green poop because of something you’re eating, oversupply, or foremilk/hindmilk imbalance. You may also be hearing that “gassy foods make gassy babies” when you’re breastfeeding, and you’re confused and concerned that you will have to somehow satisfy your ravenous appetite on salad and air.
A note about how you make milk: your milk is synthesized from ingredients in your bloodstream, not in your digestive tract. Gassy baby after that stir-fry? It probably wasn’t the broccoli … yet, you’ve read something or someone has told you that eliminating certain foods from your diet may be the answer to your crying, uncomfortable baby. How can this be possible?
A healthy, mature digestive tract (or “gut”) is “sealed;” nutrients are absorbed and wastes are contained until they are eliminated. This “sealing” takes place in a healthy, breastfed baby sometime around the middle of the first year (immunoglobulin from your milk helps to coat your baby’s small intestine in the meantime), which is why it is advised that we hold off on introducing solid foods until then; also, the first foods we introduce are hopefully less likely to be allergenic and irritating to your baby’s gut. This is where the claims that breastfeeding protects babies from allergies and eczema come from, IF our own (maternal) gut is healthy.
For many of us, though, our gut is not healthy and sealed, and is known as a “leaky gut.” Perhaps we were formula fed as babies, or we’ve been on antibiotics; maybe we have a food allergy or intolerance we don’t know about, or our diets are full of processed, irritating ingredients we’ve been led to believe are “foods” because we can buy them in the grocery store … whatever the reason, our bodies mistakenly allow proteins from foods we eat to pass into the bloodstream, where they can then pass into your milk. So, if your gut is leaky or less healthy than ideal, irritating proteins are passing into your milk and being fed to your baby, creating many of the same symptoms commonly seen in babies fed cow’s milk or soy preparations: eczema, gas, diaper rashes, and later, reactions or sensitivity to allergenic foods.
A Google search or a Facebook page may tell you your baby’s problems are caused by foremilk/hindmilk imbalance. This was once a commonly accepted explanation and “block feeding” (offering the same breast at every feed for a prescribed number of hours, then offering the other breast for the same number of hours, regardless of how many times the baby wants to feed in that time) was the preferred method for dialing down milk production and encouraging the baby to consume the fatty, satisfying “hindmilk.” Now, however, the idea that a mother makes two different kinds of milk is being challenged and the practice of block nursing doesn’t seem so vital. Nancy Mohrbacher, IBCLC, FILCA published this blog post on the foremilk/hindmilk misconception and what current research tells us.
Today, we are also thankful that the Academy of Breastfeeding Medicine Clinical Protocol #24 is available to us: Allergic Proctocolitis in the Exclusively Breastfed Infant.
From this, we learn that an exclusively breastfed baby can experience allergic symptoms as a result of maternal intake. Cow’s milk is the primary offender cited, and this is consistent with my clinical experience. All of the mothers I have worked with who had symptomatic babies reported some, if not complete, improvement after eliminating dairy products from their diet. Other mothers needed to eliminate soy, eggs, and/or gluten to bring their babies to complete relief. Some very detailed analyses of gut health, with some commentary on breastfeeding mothers and babies, can be found at this link.
Does this even relate to oversupply? If so, how? It’s clear that the symptoms in babies are similar. Some professionals suspect a cause and effect relationship, that something about the mother’s gut health causes both oversupply AND allergic sensitivity in the breastfed baby. There is no current, specific research linking maternal gut health to oversupply, but it has been my experience that most mothers with oversupply also have babies with allergic reactions to something in their milk. (Tongue tie in the baby is also very often present, but this goes beyond the scope of this post.) To me, this suggests that the mother’s digestive issues (which she may or may not be aware of – she may feel perfectly healthy and well), can result in a host of abnormal outcomes, among them oversupply and forceful let-down. While not “evidence-based practice,” rather, “practice-based evidence,” I’ve noticed over the last 7 years that the mothers who eliminated one or more allergens from their diets were delighted not only with their happier babies and normalized milk production, but with how terrific they felt without the allergen! Caring for a newborn and feeling terrific! Years later, many of these mothers tell me they never went back to the offending ingredient, or introduced it in far reduced amounts once their babies got older and/or weaned.
Do you see yourself and your baby in this post, but feel discouraged because you just went through a pregnancy where you couldn’t drink alcohol or caffeine, eat sushi, soft cheeses, or deli sandwiches, or enjoy a medium rare steak? It may feel unfair that now, you need to give up ice cream, cereal with milk, and your favorite candy bar (read the label, it has soy in it!). Don’t worry! There are so many wonderful foods you can eat! I’ve written on my blog about delicious, wholesome, healthful, real foods that won’t make your baby cry in pain.
Of course, you may choose to try other measures to resolve oversupply before changing your diet. If you’ve already ruled out possible medical reasons for hyperlactation, changing your breastfeeding position to one that makes the milk flow against gravity is one (side-lying and “laid-back” are two options) measure that is gaining popularity. “Block feeding” is still commonly recommended, but some IBCLC’s report that the method is either incorrectly communicated or not well understood, and mothers can jeopardize their milk production capability if they are not closely monitored during the block feeding period. If your IBCLC suggests block nursing, be sure to ask her to be specific about how long each block should be, and for how long you should continue the regimen. Antihistamines, sage, and mint (for example, tea made from steeping fresh mint leaves) are also ways to reduce milk production. These methods, however successful they may be, represent a resolution of the symptoms, not of the cause, therefore, even if the oversupply is corrected, sensitivities may still persist in your baby.
If you are having breastfeeding problems related to oversupply or forceful let-down, consult an IBCLC. If you would like to speak with an IBCLC who specializes in the maternal health connection to breastfeeding and healthy babies, Jennifer Tow, IBCLC at http://holisticibclc.blogspot.com offers individualized consultations, via Skype, to help you assess whether your breastfeeding issues are related to your health or diet and develop solutions that will improve your health and the health of your baby. She also offers workshops for mothers and healthcare professionals – see her site for more details.
Breastfeeding your baby can be a pleasurable, memorable experience, definitely worthy of any adjustments you may make to ensure your baby’s health and comfort. The best news: there are resources for you, and you will find solutions that work for you and your baby.
