Protect Baby's Tender Bottom
If your baby develops a diaper rash, make sure to change your baby’s diaper every three to four hours, and immediately after a bowel movement. Wipes can be irritating to raw skin, so use unscented wipes or a soft cloth with water until it heals. Allow baby’s bottom to air dry. A cream or ointment with zinc oxide can help protect the area. For prevention, petroleum ointments should do fine.
For the first three months, or longer, if your baby has sensitive skin, avoid baby wipes that have fragrances. You can also skip the wipes altogether and just use wash cloths and a squirt bottle of water at the baby's changing table.
If you use baby powder, pour it out carefully and keep the powder away from the baby's face. Talc or cornstarch in baby powder can injure a baby's lungs.
