Eczema or cradle cap

Baleigh • After having 2 rainbow babies, pregnant with #3 😊

Does this look like Eczema or cradle cap? It’s very thick and rough. She has other rough patches on her face but not as bad as this one. Her 4 month isn’t until October 15, so should I call the doctor earlier and bring her in?

I’ve tried breastmilk straight on it, milk bath, baby dove lotion, aquaphor ointment and coconut oil.
