According to the Food Research and Action Center, the federal government's child nutrition programs -- School Lunch, School Breakfast, Summer Food, the Child and Adult Care Food Program, and WIC --provide healthy and nutritious food to pregnant women, infants and toddlers in their homes, to preschoolers in child care, to children living in shelters, and to school-aged children during the school day, in the morning before school, in afterschool programs, and over holidays and vacations. For many children these programs provide more than half of the nutrition they receive each weekday.
