Coconut oil !
If you are breastfeeding or still have some milk, use your breastmilk!!
Coconut oil. Or Vaseline. It's cheap and effective. I use baby oil for babies dry scalp.
I used baby aveeno as my dd was very dry at a couple days old and within 3 days there was no more dry skin hope this helps :)
I use baby oil gel. Works like a charm
