My son is almost 1 year old. He is covered head to toe in a strange rash. It started out in one spot on his inner thigh. It seemed to be diaper rash. But now his entire body is all blotchy. He doesn't see the doctor until tomorrow. We haven't changed any soaps or anything. We did give him some milk, but haven't for a couple days. The rash is getting worse. It may be the measles. But not sure. Is there anything I can do to help him? He's very cranky.
