Could you share your daughter's diet - what foods and beverages she eats, or does not eat? Does she eat dairy products? Sugar? Wheat? White bread? Beef/chicken/pork/seafood? How much fresh fruit does she eat? Does she eat many vegetables? Does she ever drink soft drinks? Koolaid?
Is she physically active?
Has she had any other health problems?
I think that information could help curezonians in giving advice.
