However, we hardly used Cortisone for the cradle cap purpose as the cap was all gone after applied with the Baby Oil Gel. I googled cradle cap, turns out oil does work with it. I also bought the Gentle Naturals Cradle Cap Care, 4 oz (a shampoo sort of thing) from local Walmart. It worked pretty good.
The doctor told us cradle cap, he didn't mention 湿疹.
