Recommendations Needed

My 5 month old is heavily drooling and has just started to sleep on his stomach. We have tried to turn him over but he flips right back to his tummy. He has developed a drool rash on his cheeks and nose from sleeping in his drool puddles all night/naps. I’m keeping his face as dry as possible while he is awake and have been putting ointment on it to keep dry. Any mamas have product recommendations like moisture wicking sheets, crib inserts, or anything of that nature to help keep his sheet as dry as possible?
