Research has indicated that breastfeeding benefits children, mothers, and society as a whole. The U.S. government has established policies that promote breastfeeding. There is a clear need for theory-based programs that increase breastfeeding in order to reach the government's goals.

This book is a first-step at promoting a healthier, more productive society through breastfeeding in accordance with the government's Healthy People program goals.
