Those who know me in my personal life know that I am a big fan and proponent of exclusive and extended breastfeeding. When I had my first child, I was personally dedicated to making breastfeeding a success, regardless of the effort involved. After 3 months of nearly complete torture, we managed to get a solid breastfeeding relationship launched, and I was able to continue for multiple years.

These days, I am on baby number two and finding the experience to be much easier the second time around. I feel very fortunate in this. The process finally seems “natural.” I know that many women do not find breastfeeding to be easy and natural, but the benefits of sticking it out can be substantial.

Today, I came across a fascinating article on a new study highlighting the benefits of breastfeeding on infant brain development. Check out the press release here.

Researchers took infants and divided them into groups based on their primary food source – exclusive breastfeeding, exclusive formula feeding, and combined breastfeeding and formula feeding.  The infants were given an MRI to evaluate structural and functional differences in their brains.

Results suggested that infants who were exclusively breastfed had more growth in areas of their brain involved in language, emotional functioning, and general cognition.  They also had increased myelination compared to the other groups.  Larger amounts of myelin help the brain process information more quickly and efficiently.

As a science nerd and breastfeeding fan, this study really validates all the frustration and effort I (and countless other women) have put into making breastfeeding a success.  There is also some evidence in the study that including some breastfeeding gives kids an edge, although not as strong as exclusively breastfeeding.

Of course, as always, it is important to realize that correlation does not necessarily imply causation.  Other factors may be responsible for the association.  And certainly, giving your child formula does not condemn them to a life of being dull and stunted in their growth. In all honesty, I was exclusively formula fed as a baby in the days before DHA was actively added to formulas, and I managed to get a Ph.D. as an adult.  So many other things influence general cognitive abilities that one choice about feeding as an infant is not a complete determinant of later ability.

But, for those women who are struggling with frustration and self-doubt in their breastfeeding relationship – this study suggests that it is worthwhile to stick it out as much as you can.
