Diaper Rash

Diaper rash is a very common condition that can cause a baby's skin to become sore, red, and tender. The rash usually occurs because the skin is irritated by soiled diapers that are left on for too long; friction from the diaper; or certain brands of detergent, soaps, or baby wipes on sensitive skin. The plastic that prevents diapers from leaking also prevents air circulation, thus creating a warm, moist environment where rashes and fungi can thrive.




Preventing Diaper Rash


To prevent diaper rash:

  • change your baby's soiled or wet diapers as soon as possible and clean the area thoroughly
  • put the diaper on loosely to prevent chafing



Some babies with sensitive skin can benefit from the application of a preventative barrier cream or ointment with each diaper change, but not all babies need this. Some babies are sensitive to baby wipes and can alternatively be cleansed with a cotton round moistened with water.

Treating Diaper Rash

Diaper rash usually can be cleared up by checking your baby's diaper often and changing it as soon as it's wet or soiled. Creams and ointments that contain zinc oxide or petroleum help to soothe skin and protect it from moisture, and should be smeared on thickly (like icing) at each diaper change. Diaper rash usually goes away within 2 to 3 days with home care, although it can last longer.

When to Talk to the Doctor

If the rash persists, increases or if sores appear on your baby's skin, talk to your doctor. You should also seek medical care if the rash is associated with fever, there is pus draining from the rash or your child is irritable.

Depending on what type of rash your baby has, the doctor may choose to use an antifungal cream, an antibiotic cream, or a mild steroid cream for a few days until the rash disappears.
