Most parents can recognize a diaper rash when they see it. A mild diaper rash doesn’t normally require a visit to the pediatrician.
Diaper rashes usually clear up in 3-4 days with the following treatment:
If the rash is severe, see your child's doctor. The doctor may suggest using a mild hydrocortisone cream to calm the skin if it is irritated. If the rash is yeast-related, then the doctor may recommend a medicated cream. Antibiotic ointments may be used for mild bacterial infections. These creams are available without prescription, but your pediatrician may want to discuss these options before starting treatment.
Severe infections may require oral antibiotics.
