If your baby has a diaper rash, it may be helpful to remove the diaper and allow the bottom to be open to the air. Place your baby on a couple of cloth diapers or receiving blankets over a plastic sheet. If it is cool weather, keep the room as warm as possible. Don't use ointment on the skin while the diaper is off. Use soap only once a day.
Soap can dry and irritate the skin.
Be sure to use a gentle soap. If your baby has a very messy stool, it may be better to clean the baby in the tub or sink. Be sure to gently pat the area dry. Baby wipes can be irritating. They may contain alcohol which is very drying.
