DS didn't outgrow the intolerance until kindergarten. I think he may have outgrown mspi earlier but he had a nasty lactose intolerance which took its place. He would drink milk then he'd just fall to the floor screaming in agony and he had liquid...sewage like diarrhea. We had "terrible twos" but not in a tantrum sense...in a my boy is always in pain sense.
