cradle cap

Amy
My baby girl is 4 weeks old and has cradle cap just above and on her eyebrows and on her scalp. It's quite a big amount. She's had it for almost a week now but to start with I just left it alone. I then started using coconut oil as my midwife suggested but it hasn't made a difference. 
I don't want to use anything to harsh as she's so little but any suggestions would be brilliant and if you know if it works well or not.
