M.A.
I have two children, now 4 and almost 3. My oldest had major stomach problems when she was 2 months old, and the pediatrician said to switch to soy. For some odd reason, my husband went and bought the lactose-free formula instead, and my daughter was fine. We tried regular whole milk around 1 and had the same problem as before, but she was now vomiting almost daily as well. We had to switch to soy milk, but found vanilla flavor, and she loves it. With my youngest, we just started with the lactose-free formula, and switched him to lactose-free whole milk when it was time. He's never had the problems my oldest had. The lactose-free milk tends to be more expensive than the soy, so that may be a factor as well. By the way, both children can have a limited amount of regular milk (about 8 oz.) without having major problems, but any more, and we are in trouble. We also need to take into account the foods they eat that contain milk: cheese, yogurt, icecream, etc. because the total amount of dairy is what affects them now. They say that most people have lactose intolerance- I think I heard upwards of 60%, and that cow's milk really isn't the best anyway. Good luck.
