My two year old grandson had a rash suddenly appear (about a week ago) around his neck, ears, scalp, and a little bit on his back, arms and legs. It sometimes looks like it is getting better, then all of a sudden flares up again. It is making him itchy. It looks like contact dermatitis to me, but we haven't done anything new or different in regards to his food or detgergents. He has never had a problem with rashes before.
