Anyone with a 9 month old boy who can tell me how many bottles a day he drinks ?. My son eats lots. And by lots I mean 5+ times a day with baby foods/solids and still has 5+ bottles a day and his doctor says I need to take formula away from him... Obviously not all of it but apparently he has too many bottles . I don't see what's wrong with him having that many bottles if he's still eating baby food/solids the way he is . Any advice ? :/
