You might expect your baby’s skin to be flawless, but baby rashes and other skin conditions — such as cradle cap — are common.
Cradle cap appears as thick, yellow, crusty or greasy patches on a baby’s scalp. Cradle cap is most common in newborns and usually clears up on its own within several months.
In the meantime, wash your baby’s hair with mild baby shampoo and loosen the scales with a small, soft-bristled brush. For stubborn scales, rub petrolatum or a few drops of mineral oil onto your baby’s scalp, wait a few minutes, and then brush and shampoo your baby’s hair. If cradle cap persists, ask your baby’s doctor about other treatment options.
