There's nothing you can do to get rid of it, but you can help him fight the itch with Olive Oil. (it's better than baby oil) There are cradle cap shampoos and stuff, but I'm sure all they do is hydrate the scalp. Abby had cradle cap, Tom didn't. Babies either have it or they don't and it will go away on it's own. I can't remember how long it lasts, several weeks for sure. Just fight the urge to pick the scaly skin (don't do this!) You can actually leave scars on baby's head. Let the scales fall off naturally.
