Resource | Research and Data | Food/Nutrient Analysis WIC Infant and Toddler Feeding Practices Study 2 (ITFPS-2): Fourth Year Report

The WIC Infant and Toddler Feeding Practices Study 2 (WIC ITFPS-2)/ “Feeding My Baby” Study is the only national study to capture data on caregivers and their children over the first 6 years of the child's life regardless of their continued participation in WIC. Overall, the study examines child-feeding practices, associations between WIC services and those practices, and the health and nutrition outcomes of children who received WIC around birth. This report, the fifth in the series generated from this study, focuses on the dietary intake patterns and weight status of children during the fourth year of life. The report also examines families' WIC experiences and their perceptions of the program's impact.
