Actually, it is the air you breathe! One of the main causes of diaper rash is lack of air circulating around your infant's bottom. You can remedy this by letting her go dry, clean and diaperless several times a day after a rash appears.
First make sure the room is warm enough, then lay down a waterproof tablecloth or mattress cover on the floor. Cover this with a soft, washable blanket and let baby play for about half an hour.
Do this a few times a day for three to five days to help speed healing.
