C.O.
Anytime my daughter had any dairy she would have diarrhea and terrible stomachaches. She would even react if it was something baked with milk in it. We took her to an allergist when she was around 15 months old and he is the one that diagnosed her food allergy. Because she would have a reaction to milk even in baked goods he felt it was an allergy not a sensitivity or lactose tolerance. She was also allergic to corn. When ever she had corn she would get a rash around her mouth and become very moody. She just wasn't her happy go lucky self.
