The overall goal of the PROBIT study is to investigate the influence of a randomized breastfeeding promotion intervention designed to increase the duration and exclusivity of breastfeeding ("the breastfeeding promotion intervention") on the development of maternal and child health outcomes. The hypothesis is that randomization to the intervention will be associated with lower child adiposity, lower risk of asthma and atopy, improved lung function, and improved cognitive outcomes.
