Help Your Patients Breastfeed...Safely and Comfortably

Research of mothers’ opinions about their breastfeeding education and support from professionals is very clear: they are not satisfied. Parents want information that is more personalized, less authoritarian, and more realistic; in this survey of over 1,000 women who had initiated breastfeeding, 85% of mothers disagreed that “methods of breastfeeding promotion and education are currently excellent”; only 18% of mothers reported being happy with the information they received from health professionals during pregnancy.


This systematic review showed common complaints:

  • Support was rigid and impersonal
  • Insufficient practical support postpartum
  • Being given unrealistic expectations prenatally
  • Education was “strict and dogmatic,” and omitted information about alternative feeding methods such as bottles
  • HCPs withheld information about formula
  • Perpetuated guilt
  • Experienced verbal and physical pressure.

Our breastfeeding education and protocols are out of date, and much of it is inaccurate

Source: Global Health Media, an educational resource for health care providers that provides excellent videos on positioning and latch.

As a result:
  • Six percent of exclusively breastfed babies are readmitted to the hospital, usually from complications of insufficient breastfeeding such as jaundice and dehydration. 

We have an ethical obligation to teach parents how to keep babies safe and free from hunger and thirst; this supersedes our responsibility to meet exclusive breastfeeding targets.

Number of studies showing that “most mothers, with rare exceptions” can make enough milk to support optimal infant growth from 0–6 months: ZERO

  • Newborn stomachs are not “tiny”; they are approximately 20 ml at birth, and they have been swallowing 500-1000 ml of amniotic fluid/day. They quickly learn to self-regulate, following their bodies’ hunger and fullness cues.

  • Five randomized controlled trials showed that judicious supplementation for excess weight loss (≥4.5%) did not disrupt breastfeeding (1,2,3,4,5) and reduced readmission for feeding complications (4). See http://newbornweight.org for weight loss percentage by hour of life nomograms.
  • When a baby is nursing constantly and still exhibiting hunger cues, they are not “just cluster feeding” or experiencing so-called “second night syndrome.” Showing constant hunger cues and nursing nonstop for hours means they are hungry.

Five milliliters of colostrum contains 3 calories. A 3000 g baby burns three hundred calories per day.

So where are they getting those 300 calories? The theory is that since healthy term AGA newborns have sufficient fat stores and glycogen to tolerate brief periods of very low feeding volumes. (No one has looked specifically at the long-term effects of low vs metabolically appropriate volumes in the first few days, because it is assumed that if this is the “biological norm,” it must be best). The Academy of Breastfeeding Medicine assumes this is optimal—and safe—because it “emulates evolutionary feeding.” 

  • Glycogen stores are exhausted after 12 hours of life, and many babies either do not store enough reserves (e.g., LPT babies) or have already burned through them (e.g., in a long or difficult labor).
  • Ketones as alternative fuel do not provide sufficient protection for newborns. 
  • Babies have different calorie and fluid needs, based on their weight, gestational age, stresses during labor, and other factors such as cold stress or prolonged crying. The viscosity of colostrum, which makes it ideal for coating mucosal surfaces with sIgA antibodies, reflects its relatively low level of water content compared with mature human milk, and while it is high in protein, it is lower in calories and carbohydrates than mature milk. 
  • If a baby does not get enough calories to support their metabolic needs, they will start digesting their own tissues to provide those nutrients (autophagy).
  • Normal (i.e., natural) postnatal survival rates in humans and other mammals are not great.

There is no evidence that it is sufficientlet alone optimalfor a newborn to have only drops of colostrum in the first 24 hours

If “evolutionary feeding” is going to be our model, we must also listen to the powerful evolutionary strategy newborns have developed to get their needs met—crying. We must also listen to mothers, who have an equally powerful drive to respond to their babies’ cues and feed them until they’re satisfied.

In fact, withholding calories is probably one of the worst things you can do to babies’ future ability to breastfeed. Underfed babies sleep to conserve calories. Sleepy babies rarely breastfeed effectively. Effective breastfeeding (or pumping) is necessary for establishing a good milk supply. More here

  • Guidelines stating that 2–10 ml/feed of colostrum are enough are based on only four small studies (1984, 1986, 2001, and 2003; total n = 84) of average colostrum transfer in healthy, successfully breastfeeding dyads—not what is optimal or safe for all babies. (These researchers did not check babies’ glucose, bilirubin, weight loss, or sodium levels.)

Newborns are the only patients that must show clinical and laboratory evidence of dehydration and underfeeding before being given ad lib nutrition and fluids

Frequently Asked Questions:

Q: Should all babies be supplemented? 

A: No. Many mothers make enough colostrum.

Q: How will I know which ones need supplementing? 

A: Easy—listen to mothers, listen to babies, and trust your clinical judgment. If you are unsure, the safest and most breastfeeding-supportive intervention is to supplement and teach milk expression. Here is some supplementation guidance. This intervention must only be done with parental informed consent and education on when to return to exclusive breastfeeding (usually after the milk comes in and it is confirmed that the baby can transfer effectively).

Q: If babies are voiding and stooling, doesn’t that mean they are getting something?

A: Diaper counts do not reflect babies’ intake in the first few days because of normal diuresis and bowel functioning. Even babies who are NPO produce stools. The volume, frequency, and color of urine can be clues as to the baby's hydration, but the most accurate measures are test weights on a scale accurate to 2 g and their weight loss percentile on the Newborn Weight Loss Tool

Q: Should we still be encouraging breastfeeding?

A: Yes! Most mothers want to breastfeed, and human milk provides human-specific nutrition, antibodies, and other bioactive components.

Q: What about babies who wont go back to breast after a bottle?

A: Most babies go back and forth fine, as long as they aren't too hungry and aren’t being forced. This 2020 study showed that the mechanics of breast- and bottle-feeding are similar. Evidence is conflicting on the concept of “nipple confusion” and “flow preference” with bottles (4 studies found evidence and 2 did not, and none of them established causality). However, if mothers are concerned about this possibility, here are some strategies

Q: Is cluster feeding normal for a neonate? When does frequent feeding become a sign of insufficient intake?

A: Cluster feeding is defined by the Academy of Breastfeeding Medicine as “several short feedings close together.” It is normal in a baby who is gaining weight well. However, in a newborn who is still losing weight, constant crying and continued hunger cues even after feeding are usually signs that they are not satisfied.

Q: Could suggesting supplementation affect mothers’ confidence?

A: There are no studies showing that temporary judicious supplementation decreases maternal confidence in long-term breastfeeding success. Most mothers who have been pregnant and delivered a baby have experienced a little technology being used to reduce risks and/or augment their body’s natural birthing process. They are often relieved to have a strategy to address their baby's hunger and their own need for rest, the latter being important for the mother's health and desire to continue breastfeeding. 


In fact, mothers often feel more confident when their observations about their babies’ hunger are validated. It demonstrates clearly that they have good instincts and can trust themselves to know if their baby is satisfied or not. Knowing they can trust their own judgement also empowers them to know when it would be appropriate to discontinue supplementing. 

Q: Is there long-term harm to the baby’s microbiome with the introduction of formula?

A: No.

Q: What about triggering allergies to cow’s milk, or other possible harms?

A: There is no harm of formula that equates to the risks associated with insufficient feeding, let alone small, temporary amounts. Long-term effects of breastfeeding and formula feeding are summarized here, and allergies in particular are discussed here.

For babies with a family history of cow’s milk allergies, a hydrolyzed formula may reduce risks, but the evidence is not strong.

"Twenty-five years ago my son almost died. I had chosen to breastfeed, as everyone around me kept reminding me that ‘breast is best.’ Even though I felt like something wasn’t quite right those first few days, everyone assured me everything was fine....that 'the great thing about breast milk is that you never have to worry about how much or how little he’s getting. Because he’ll always get what he needs."Pamula Floyd, mother of Chaz, who had a stroke from hypernatremic dehydration at 6 days old and now lives with cerebral palsy. Full story here.

“[Landon] cried unless he was on the breast and I began to nurse him continuously…when I asked them why he was always on my breast, I was told it was because he was ‘cluster feeding.’ I trusted my health care providers.”Jillian Johnson, mother of Landon, who suffered a cardiac arrest due to hypernatremic dehydration 12 hours post discharge. He did not survive.

“After I gave birth to my son, my baby was very hungry and cried inconsolably. I was concerned there was no milk coming out of my breasts. I told my husband to go buy baby milk to give to our son until my breast milk flowed. But my doctor was opposed to this idea, saying that exclusive breastfeeding is the best. I listened to my doctor.”Josephine ​(last name withheld), whose baby died at two weeks of age, after multiple health care providers told her he was getting enough milk.

“Do not EVER feel bad or guilty about not being able to ‘exclusively breastfeed’ even though you may feel the pressure to do so based on posters in maternity wards, brochures in prenatal classes, and teachings at breastfeeding classes.”
