Cradle cap is very common. If your baby's scalp has flaky, dry skin that looks like dandruff, or even thick, oily, yellowish or brown scaling or crusting patches, it's most likely cradle cap. Once your baby's cradle cap is completely gone, it's unlikely to return, but to help remove dead skin while it's waning, you might want to give your baby more frequent shampoos. Don't overdo it, though, or you could further stimulate his oil-producing glands. A gentle wash two or three times a week with a mild shampoo should be plenty.
