The primary objective of this study is to evaluate the efficacy of a specialized exclusive breastfeeding education and support program targeting obese, pregnant, low-income women in Hartford, CT. Specifically, the investigators will evaluate the impact of the intervention on exclusive and partial breastfeeding rates at birth, 1, 3 and 6 months pp. Secondary aims of this study are: a) to characterize postpartum weight loss patterns and blood pressure values of obese women, by study group; and b) to evaluate potential differences in infant morbidity (diarrhea, otitis media and rehospitalization), by study group.
