When My son was about 8 months, this happend to him, I tried using baby oil but it was not the liquid, it was gel with aloe vera and vitamins in it. This helped some what. I would take a baby brush and kinda lightly rub the scalp with it and the baby oil. You could also look for an oatmeal shampoo or a shampoo that is just for cradle cap, they usually have some at Wal~mart, sometimes you might find these in the baby section or in the pharmacy area where they have some baby things. I tried all of these and when this was not clearing it up anymore, we went to the doctor, my son's regular doctor, and he gave me a prescription for Selenium Sulfide lotion, which is generic for Exsel Lotion. Might take your little one in and have it looked at. But don't worry its normal for any baby, some just need a little extra help clearing it up.
