The other day I read on a post that someone said... "Don't use soy unless it's your LAST resort" so I just wanted to know why. What's wrong with it. My son hasn't been taking ANY formula well not even total comfort. his family told me they have a lot of lactose intolerant people in the family so I would probably have to give him soy. And I'm taking him back to the Dr tomorrow to get another opinion. So I just wanted to know if there's something wrong with it
