Cradle cap?

Abi • 22- Mommy to baby Hugo 06.03.19👶🏻💙

Hi all, little one is now 17 months, the last week I have noticed yellow flaky dry patches all over his scalp.

I always use non-perfumed baby wash and shampoo anyway as he is a dry skinned baby.

He never had craddle cap or anything as a baby and it’s only come up randomly. I had been using oil and combing bits out but is he too old for craddle cap? Could it be anything else?

Thanks ladies.
