Hello , Thanks for posting your query, Check your baby's diaper often, and change it as soon as it becomes wet or soiled.
Use plain water. Only use soap if you need it to get stool off.
Gently pat the area clean and dry, rather than rubbing.
If you use wipes, choose mild ones while your baby is fighting diaper rash. Try to avoid those with fragrances or alcohol while your little one's skin is irritated. Or use a clean, soft washcloth.
Be sure the area is completely clean and dry before putting on a fresh diaper.
Bad rashes call for extra measures!

Try a squirt bottle to wash the area well, without rubbing sore skin.
Let your baby go diaper-free as much as possible. Airing out the diaper zone helps a baby's skin heal faster. To avoid a mess, do it right after a bowel movement.
Creams, Ointments, and Powder

These products aim to soothe a baby's sore skin or create a protective barrier -- or both.

Smooth on cream or ointment to your baby's clean, dry bottom before putting on a clean diaper. Look for zinc oxide or petrolatum (petroleum jelly) in the ingredient list.
If you use baby powder, take care to keep it away from the baby's face. The talc or cornstarch in the powder can cause breathing problems.
