does anyone have any experience with this? DS was 2 last month and about 2 weeks ago began a rash that has gotten steadily worse. It's really nasty looking, although it doesn't bother him. The pediatrician misdiagnosed it, it go worse so we went back and were refered to a pedicatric dermatologist, so I guess it's not that common if the pediatriction didn't know what it was. I'm just worrying about how much worse this will get and how often he will get it. If your child has had it, do they get it often? I hope not since this is the 1st time he's ever had it.
