My son is 3 1/2 months old and still has cradle cap on the top of his head. The pedi said to use baby oil before bath time and let it sit for 15 minutes, then use a brush to try to brush out the flakes. Thing is, I get so nervous that it's creating raw skin. Also, it's on his soft spot. Should I be worried about brushing that area? Anyone have a similar experience? Any help would be appreciated.
