California has a group called the California Food Policy Advocates (CFPA) which educates and advocates for food policy with the state legislature. There is a division focused on child care policy and CFPA has created a fact sheet for the CACFP Meal Pattern Proposed Rule. While the numbers are specific to California, much of what's shared is pertinent to anyone involved in child care nutrition.
CFPA is an effective group for efforts to establish policy for nutrition in child care. Know about what they do and look for a group that focuses on policy in your state - it's an important part of the system.
