If there is a persistent, mild diaper rash you might try treating it before you need to call me. Expose the rash to air for ½ to 1 hour 4 times a day. Avoid using plastic pants. A good adhesive cream or ointment containing zinc oxide applied to the involved area 4 times a day will protect the skin and aid in healing. If these measures don’t help after a few days or the rash becomes painful, call the office.
