Cot probelms

Me

How do I stop my daughter from getting stuck in the corner of the cot? She moves around a lot when she’s asleep. And for the past 2 weeks at least twice a night she cries cause she’s gotten stuck and I have to get up to move her. We have the mesh bumpers on because her legs used to get stuck but she still manages to squeeze into it and can’t figure out what to do.
