If it is a diaper rash, letting the baby air dry is always recommended by our pediatrician, but of course there could be a mess! A wet rag is a good idea as well. When my kids would get really nasty diaper rashes, I used any diaper rash ointment I could get my hands on, and then put Vaseline over it.
If it is a yeast infection, some Vagisil would do the trick. Good luck!
If it is truly a rash, there is a good possibility for yeast infection. Our doctor prescribed a tube of Nystatin ointment. It works wonders. We don't use it unless it gets that yeasty look.
If it is a big red area that is irritated from his bowel movements, like diarrhea, his bottom could actually have a mild burn from the acid in his stool. Wipe milk of magnesia on his bottom with cotton balls as often as you can. This cools the burn and helps the skin actuall heal. My pediatrician told us to do this when my son had a bunch of loose stools in a row.
good luck
