Yeah, you can have a dairy allergy. My best friend from high school's older son had a milk allergy when he was a baby. Any time he'd drink dairy based formula, he'd break out in a rash on his face and the rest of his head. Just another one of the reasons I'm going to be breast feeding when I have kids.
