Baby's leg getting caught between crib slats

Brittany 💙 6/1/2020

So last night, it happened twice. He woke up screaming super loud so if course I run in there (he is in his own room). Both times he had his leg out through the crib slats. I'm afraid he's going to hurt himself. I know they make bumpers but you're not supposed to use them. He moves around all night long and flips to his belly so no matter where I lay him down for the night, he ends up somewhere else. Any advice?
