The WIC Infant and Toddler Feeding Practices Study 2 (WIC ITFPS 2), "Feeding My Baby Study" captures data on WIC caregivers and their children over the first 5 years of each child’s life to address a series of research questions regarding feeding practices, the effect of WIC services on those practices, and the health and nutrition outcomes of children on WIC. Additionally, the study assesses changes in behaviors and trends that may have occurred over the past 20 years by comparing findings to the WIC Infant Feeding Practices Study–1, the last major study of the diets of infants on WIC. This study will provide a series of reports. The current report focuses on breastfeeding intention, initiation and duration, and the introduction of complementary foods.
