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.
Leave your baby's bottom exposed to the air as much as possible each day. When the diaper is on, fasten it loosely so that air can get between the diaper and the skin. Rinse the skin with warm water. Don't use soap. Use creams and ointments.
