Cradle cap is a common newborn rash that appears as thick, yellow, crusty or plates or scales on baby’s head, although it can also appear on his face. Cradle cap usually clears on its own in baby’s first 6 months of life but you can use a mild baby shampoo and a soft infant brush or comb to gently loosen and remove the scales. Tackle stubborn scales with a small amount of mineral oil, applied to soften the scale, and then remove with the brush or comb. It typically goes away by baby’s 6-month birthday. Alert baby’s healthcare provider if cradle cap continues to spread, especially to baby’s face.
