This final rule incorporates into the regulations governing the Special Supplemental Nutrition Program for Women, Infants and Children (WIC) several changes set forth in the Healthy, Hunger-Free Kids Act of 2010 (HHFK Act). These provisions address: certification periods for children participating in the WIC program; increased emphasis on breastfeeding promotion and support; compiling and publishing data for partially and fully breastfed infants; sharing nutrition education materials with institutions participating in the Child and Adult Care Food Program (CACFP); and infant formula (and other foods) rebate management.
