WIC is short for "The Special Supplemental Nutrition Program for Women, Infants, and Children." It serves low-income pregnant, breastfeeding, and postpartum women, and children up to age 5. Besides food, it provides nutrition education and referrals to healthcare and social services.
Question: What percent of all infants in the US participate in WIC?
These pictures of cereal and eggs are from Washington State's WIC Approved Food List. From what I can tell, states share their graphics with the USDA. Washington State must have had a pretty good graphic set to get prime link space on the USDA's WIC page.
You can see the rest of their brochure at Washington State WIC Program (pdf). I learned a lot looking at this.
