Ouch! I couldn't help but reply. I think I have some experience with red bums. First keep her dry! Very important since bacteria love moist places. Powder helps, you can make your own or buy good stuff. Let her run free (birthday suit style ) when it's safe. Also try disposable diaphers for a while, just to see if it'll clear up. Maybe a week. You could go into healing it from the inside but that can get very complicated. I'm very sorry . I hope you can find some good help.
