Skin tips for 5mo old

Dominique • Myles John 3/8/16. Micah Robert 6/29/17 baby girl due 10/8/20

I have been putting aquaphor on his cheeks which seems to help them not be so chapped but it does not last very long.

For his neck I’ve tried AD diaper rash cream and the aquaphor but it just stays wet. Any tips on how to clear up the rash and dry/chapped skin??

He’s teething really bad and no stops drools and always chewing on his hands (which are also chapped)
