Is anyone dealing with cradle cap?

My daughter is 4 months old and has a mild case of cradle cap. I had noticed it since she was a newborn and I thought it would go away on its own but it didn't seem to. Today I decided to comb it out of her hair. She seemed okay but I read that combing it out may cause irritation. I put a bit of baby oil in her hair and she seems content.

How did you get rid of your baby's cradle cap?
