My 11 month old son has hand foot and mouth is there anything i can put on the blisters there bad on his face and private area ?

Wear gloves: No sharing toys, wash hands. Cool cream, or something cool on his blister, wraping something in a towel from the freezer), for a few minutes at a time, using Acetaminophen (tylenol, not aspirin), .

No: The rash associated with hand-foot-mouth disease causes no itching but elicits pain. It is prudent providing him analgesic such as tylenol (acetaminophen) and plenty fluids.
