Change diaper frequently. During each diaper change, use plain water or mild soapy water and a soft cotton cloth or cotton balls to clean baby's bottom. Pat dry with a soft cloth. Avoid disposable baby wipes that contain alcohol. Try to give your baby a good deal of diaper-free time each day.
Fresh air works wonders on diaper rash.
Change diapers as soon as you know they are wet or soiled. Use a mild detergent to wash diapers. Double rinse if child already has a rash. If you use cloth diapers, opt for more breathable diaper covers than plastic or rubber pants. This to a Friend.
