Freaking out what should I do

He will literally cry and scream if I pull the burp rag away 😭 I’m not sure I’ll be able to sleep tonight

He usually lays flat on his back and no burp rag but he’s refusing to let go 😭 he just starting doing this today during nap time right when I lay him down he automatically turns to his side and it kinda scares me he’s 7 months but he’s not really active on his belly or lays down much (when he’s up he always sits everywhere he’ll never just lay down and relax not his thing) unless he’s sleeping so he doesn’t do tummy time he hates being on his belly so I never enforced it and he will flip from his belly to his back but the other way around
