We had similar problems with my daughter and she was on that same formula. The very first thing my doctor did was to get her off milk based formula. That is the number one allergen in children. Her problem vanished, but to this day if she has too much milk her ears will begin to get infected. She is 17 years old. My brother also was hospitalized as a baby over an undiagnosed milk allergy. The best first step you can make is to get rid of milk, but after that you need to look at dust, pets and mold. Hope this helps. K.
