It's so nice to see some celebration of people's choices. As someone else said, why is it anyone else's business what/how you feed your kids?
The whole judgment factor seems so strange to me...how many people would feel justified in judging parents over similar dietary factors wit older kids? I see it as being something like the difference between a balanced diet made entirely from scratch using whole foods, and a balanced diet that includes some processed foods. Sure, formula may not be "perfect", but nor is the diet that the vast majority of kids will eat when they're older. It's still a healthy balanced diet, and there can be so many more important factors when it comes to feeding a child (such as the family's sanity), than whether the diet they're consuming is nutritionally the best possible.
