How do you know what foods your kids can't tolerate? Maybe my son's behavior problems stem from a food issue. He couldn't tolerate dairy as a baby but has been able to tolerate ice cream and cheese as he's gotten older. He now doesn't like cow's milk - he drinks soy (which someone told me you're not supposed to give to boys because it inhibits brain growth:) ). He had multiple ear and sinus infections after we switched from breast to dairy formula, which cleared up immediately when we switched to soy formula (about 12 months old) when my mom thought to tell me "oh, two of your sisters couldn't tolerate dairy".
Do you just have to start eliminating things from their diets? What do you look for to see if things are better/different? Might be worth a try for us. Seems like someone noted above the most common intolerances are soy, dairy, and gluten.
