Hi, my daughter is 2 years old and she has developed a rash over the last week. We noticed she was scratching her head vigorously on Saturday evening and all day Sunday. On Monday, small pimple-like spots appeared on her face. By Tuesday, they were all over her body. We took her to the pediatrician on Thursday when it became apparent that she didn't have anything like chickenpox. She hasn't had ANYTHING "new" to eat or drink and she has no known allergies. Today, she had a little bit of blood in her diaper. We thought maybe it was from constipation, but her "mystery rash" is still all over, causing her to itch like crazy, and we're feeling paranoid.
