Does anyone know a good remedy for diaper rash, other than desitin (zinc oxide diaper cream) or a&d?

Open to air. The best remedy for diaper rash is to clean the area thoroughly and often. After cleaning air dry or fan with your hand or use a blow dryer on cool. Leave the diaper off when you can. Creams are basically a barrier and when using take care to dry the area off well before applying. Also some diaper rashes will require medicated cream. You may want to call your pediatrician.
