Alternative names:

Home care:
DIAPER RASHES
Keep the skin dry. Change wet diapers as quickly as possible. Allow the baby's skin to air dry as long as is practical. Launder cloth diapers in mild soap and rinse well. Avoid using plastic pants. Avoid irritating wipes (especially those containing alcohol) when cleaning the infant.
Ointments such as Desitin or zinc oxide may help reduce friction and protect the baby's skin from irritation. Powders such as cornstarch or talc should be used cautiously, as they can be inhaled by the infant and cause lung injury.
BABY RASHES
Heat rash is best treated by providing a cooler and less humid environment for the child.
While powders do not harm the child, they are unlikely to help the condition. Powders should be stored out of reach of the infant to prevent accidental inhalation. Avoid ointments and creams because they tend to keep the skin warmer and block the pores.
Normal washing is usually all that is necessary. Avoid acne medicines used by adolescents and adults.
OTHER SKIN PROBLEMS
For skin problems caused by pityriasis alba, patches may come and go for years; but between ages 20 and 30, they will disappear completely. Use sunscreen or protective clothing to prevent sunburn in affected areas. Use topical (applied to a localized area of the skin) steroids as directed by the doctor.
For skin problems caused by allergic purpura, the condition usually lasts between 1 and 3 weeks. Warm soaks in the bathtub may help relieve joint pain. Otherwise, follow prescribed therapy.
For skin problems caused by eczema, the keys to reducing rash are to avoid scratching, and keep the skin moisturized. Keep the fingernails short and consider putting soft gloves on small children at night to minimize scratching. Drying soaps and anything that has caused irritation in the past (including foods) should be avoided. Apply a moisturizing cream or oil immediately after baths to avoid drying. Hot or long baths, or bubble baths, may be more drying and should be avoided. Loose, cotton clothing will help absorb perspiration. Consult a doctor if these measures do not control the eczema, or if the skin begins to appear infected. While the majority of children with eczema will outgrow it, many will have sensitive skin as adults.
For skin problems caused by prickly heat or sweat retention, remove excess clothing and consult your doctor if the rash lasts longer than 24 hours or the child seems ill.
For cradle cap, use half-strength coal-tar cream on affected areas. The pharmacist can provide this without a prescription. Cradle cap usually disappears by 18 months. If it does not disappear or becomes infected, or if it is resistant to over-the-counter treatment, consult a health care provider.

The baby's skin will be thoroughly examined to determine the extent and type of the rash.
Diagnostic tests that may be performed include: Intervention:
Nystatin cream may be prescribed for diaper rash caused by yeast. If the rash is severe, a corticosteroid cream may be recommended. Oral antibiotics may be prescribed if a bacterial infection is diagnosed.
For eczema, the doctor may prescribe ointments containing coal and tar or cortisone drugs to decrease inflammation. Antihistamines may be recommended to decrease itching.
Once in a while, a sedative or tranquilizer may need to be prescribed.
After seeing your health care provider:
If a diagnosis was made by your health care provider related to your baby's rash, you may want to note that diagnosis in the personal medical record.
