Interesting post about WIC. I had the total opposite feeling with my oldest. At first, I was so excited, seeing the BFing posters, but the overall experience was really NOT helpful. I was asked at every visit if I needed formula vouchers, given some seriously dirty looks when nursing an older child, and told to give more dairy to my toddler, despite his still-frequent nursing. The default position at WIC is formula feeding, and the BFing posters are often little more than window dressing.
This has also been my experience. I found them more helpful when I had foster kids in the program.
For my own breastfed child I had to fill out the dietary sheets showing that she drank so many ounces of milk each meal because they did not accept breastmilk as an answer or that I didn't know how much. I just had to give in and play the game. At the time my husband was deployed overseas and I needed the program. Some may not agree but I felt the supplemental food helped me continue to nurse although I know their intent is that the food be fed to the child directly.
