Diaper rash is any rash on the skin area covered by a diaper. Almost every child gets diaper rashes.
Diarrhea causes rashes in most children, too.
If rashes do not get better, your child may get a yeast infection. You will know your baby has a yeast infection when the rash becomes bright red and raw, covers a large area, and is surrounded by red dots. Change diapers frequently. Keep the area dry and clean. BMs cause most of the skin damage.
