Toddler was lethargic and off food with a high temp over the weekend. Seems fine today but noticed blisters around his mouth. In further inspection I found some on his hands, feet and groin area so assumed hand foot and mouth. It seems to have spread now though and have seen some on his legs and face. Could it be chicken pox? Also I've just changed baby's nappy and she has 3 blisters on the groin area but nowhere else
