Children’s HealthWatch finds that young children who participate in the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) are more likely to be in excellent or good health and have a reduced risk of developmental delay compared to children who are eligible for WIC but not enrolled.  WIC provides vouchers for foods high in essential nutrients to young children and pregnant and postpartum women.  Investing in WIC not only provides cost savings in infant health care, but also supports the nutritional needs of young children during a critical window of brain and body growth. Program improvements that decrease access barriers, provide the full amount of recommended fruits and vegetables, and accommodate working parents will help young children reach their full potential.
