You are absolutely right. He NEEDS that specific nutrition found in formula. After he turns 1, then you can switch him to whole milk in a sippy cup, but until his first birthday, he needs that formula. His body is not mature enough to break down the nurtients he needs from regular foods. Not to mention, aside from baby food, there are limited foods he can eat since he has very few teeth. He needs the iron and protien especially from the formula. I worked for a while in a very large pediatric practice, so I gained a lot of knowledge on things like this while I was there.
