My son had this when he was that age, too! It is aweful aweful aweful!! And it is just as catching as chickenpox. It is a form of chickenpox, so if you have never had chicken pox be careful. My roommate caught it from my son and had it on her hands and feet only. My son couldn't eat anything but soup till it was gone. They treat it just like chickenpox. So anything you can find to treat that will work. In the mouth advil alternated with tylenol or coat it with a maalox type substance will ease the pain a little (at least it did for my son). go to webmd and search they have helpful hints as well. GOOD LUCK!! It'll pass soon but not soon enough> J.
