The little I know about WIC comes from what I learned from my foster daughter's case. You are allotted a certain amount of items - fruit, dairy, grains etc per month per child. You have a card just like a debit card and the WIC eligible items are noted on the shelves at the grocery store. There are quite a large variety and surprisingly, to me anyway, the grains are whole grains and the dairy low fat (I think under 2 you can get whole milk). So I could buy whole wheat taco shells but not the white ones. We don't opt to take WIC for FD because we simply don't need it and you have to meet with a nurse every month and I've heard from other foster parents that its not pleasant. If she was on formula I would probably do it, but the amount we get in board covers the amount she eats.
