Providing Nutritious Milk to Children The Special Milk Program (SMP) provides milk to children in schools and childcare institutions who do not participate in other federal meal service programs. The program reimburses schools for the milk they serve. Schools in the National School Lunch or School Breakfast Programs may also participate in the Special Milk Program to provide milk to children in half-day pre-kindergarten and kindergarten programs where children do not have access to the school meal programs.
