C.S.
If it is diaper rash, then I know a great remedy from a friend who works at Children's Healthcare of Atlanta. Using a hand mixer or blender, combine equal parts Aquaphor and either Maalox or Mylanta. (You have to use name brand Maalox or Mylanta; the generic won't work this time.) It will be a little bit runny, and it may not fully combine, but that is okay. Apply this to the effected area, and, if it is diaper rash, it will be cleared up within a day or two. My son was a thumbsucker, and this was also a great ointment to relieve the red chapping he would get from the drool sitting on his face while he sucked his thumb. Hope this helps!
