Brains of Breast-Feeding Moms More Responsive to Baby's Cries

In a finding that won't surprise many mothers, a new study says breast-feeding may help secure the bond between mother and child. But the study also offers one explanation how: through a change in the mother's brain.

The brains of breast-feeding mothers show a greater response to the sound of their babies' cries than do the brains of mothers who do not breast-feed, the study researchers say.

This boost in brain activity is seen in brain regions associated with mothering behaviors.

The results suggest this brain activity facilitates greater sensitivity from the mother toward her infant as the baby begins to socially interact with the world, the researchers say.

The study may help people to "recognize that it's important to support mothers who do want to breast-feed," said study researcher Pilyoung Kim, of the National Institute of Mental Health.

I understand the challenges mothers have," Kim said. "Regardless of their decision, I think it is critical during this early postpartum period that they seek support and encouragement from others, especially when they feel very stressed and challenged by the new demands because of the new parenting experience.
