“Breast Milk From Bottle May Not Be As Beneficial As Feeding Directly From The Breast, Researchers Say.” This was the headline on the AAP Daily Briefing that was sent to American Academy of Pediatrics members on Sept 25, 2018.

I suspect that this finding doesn’t surprise you. I can imagine a dozen factors that could make bottled breast milk less advantageous for a baby than milk received directly from the mother’s breast. Antibodies might adhere to the glass surface. A few degrees above or below body temperature could interfere with gastric emptying. Or a temptation to focus on the level in the bottle and inadvertently overfeed could inflate the baby’s body mass index at 3 months, as was found in the study published online in the September 2018 issue of Pediatrics (“Infant Feeding and Weight Gain: Separating Breast Milk From Breastfeeding and Formula From Food”).
I agree that the title of the actual paper is rather dry; it’s a scientific research paper. But the distillation chosen by the folks at AAP Daily Briefing seems ill advised. They were not alone. CCN-Health chose “Breastfeeding better for babies’ weight gain than pumping, new study says” (Michael Nedelman, Sept. 24, 2018). HealthDay News headlined its story with “Milk straight from breast best for baby’s weight” (Sept. 24, 2018).
The articles themselves were well balanced and accurately described this research based on more than 2,500 Canadian mother-infant dyads. But not everyone – including mothers who are struggling with or considering breastfeeding – reads beyond the headlines. How many realize that “better for babies’ weight gain” means a slower weight gain? For the mother who has found that, for a variety of reasons, pumping is the only way she can provide her baby the benefits of breast milk, what these headlines suggest is another blow to her already fragile sense of self-worth.
This research article is excellent and should be read by all of us who counsel young families. It suggests that one of the contributors to our epidemic of childhood obesity may be that bottle-feeding discourages the infant’s own self-regulation skills. It should prompt us to ask every parent who is bottle-feeding his or her baby – regardless of what is in the bottle – exactly how they decide how much to put in the bottle and how long a feeding takes. Even if we are comfortable with the infant’s weight gain, we should caution parents to be more aware of the baby’s cues that he or she has had enough. Not every baby provides cues that are obvious, and parents may need our coaching in deciding how much to feed. This research paper also suggests that as long as breastfeeding was continued, introduction of solids as early as 5 months was not associated with an unhealthy BMI trajectory.
Unfortunately, the reporting of this research article is another example of the hazards of the explosive growth of the Internet. There really is no reason to keep the results of well-crafted research from the lay public, particularly if they are explained in common sense language. However, this places a burden of responsibility on the editors of websites to consider the damage that can be done by a poorly chosen headline.
