Pooped while sleeping

Sh

So this is the second time my son has pooped in his sleep and gotten pretty awful diaper rash from it. The first time it was more his butt though and this time it’s his penis 😭 it’s SO raw and red and he barely lets me touch it. It’s a tiny bit better than this morning but not by much.

My plan is to give him a bath with some

Epsom salts, let him air dry and then use Vaseline on it. Anyone have any other tips? Anything to keep an eye out for?
