DS has had a red cheek for a couple of days, he says its itchy and the skin is a little bumping, otherwise he is fine. Teacher mentioned it to me today and said I should check it out because it is contagious. Ive looked it up and read that once cheeks are red children are no longer contagious, so Im guessing I dont need to keep it at home tommorrow. But, could it be anything else, I dont want to bother the doctor unless I really have to as he is totally fine in himself.
