11 monther getting legs stuck in crib slats

Meredith • Mother to my rainbow baby girl 10/21/16 and 1 on the way due 1/4/19 🌈🌈

How do I fix this? I have one of those breathable bumpers but she's so wiggly getting herself to sleep she frequently puts legs over that and through slats.. most of the time she can get herself unstuck but it freaks me out! Any ideas?
