Hi Kristen,
I have found putting baby oil on her scalp daily, sometimes even a couple of times throughout the day, has taken care of the cradle cap. My hairdresser swears by using Paul Mitchell Baby Shampoo. She would put it on the baby's head at the beginning of the bath and let it sit there while she finished bathing her. She would then rinse it off. I have also read doing the same with regular dandruff shampoo, letting it dry, rinsing it off and then using a baby brush to slough it off. I would not use a finger nail but a brush might be a littler gentler. Good luck.
