Yellow, scaly, flakey skin on little ones eyebrow. Is this cradle cap?

Yep, agree with polar mummy. Definitey looks like cradle cap. It's pretty harmless but if it bothers you, you can apply coconut oil as suggested or lotion.

You can also apply baby oil and gently massage in, after the oil dries up, the skin will come off easily.

Looks like cradle cap. Use coconut oil on it.
