Baby dry skin!!

Alejandra • Baby Boy Thiago was born September 23, 2016💙
My son is three months and his skin has become so much more dry to the point it's come almost flaky on his back, I have to moisture him morning, afternoon and night. And every three days we give him a bath with aquaphor wash. We're currently using aveno eczema cream, and I don't think it's cutting it. Do you guys have any recommends?
