TIPS?! Advice?!

Sa
Our little girl recently started scooting/crawling in her crib at night... so much so that we out her at one end and in half a minute she's moved to the other end and pressed herself up against the mesh bumpers/crib rails. She then cries because she's stuck and uncomfortable. 
Has this happened to anyone else? Did it last long? Any tips?! She's normally such a GREAT night time sleeper, and this is throwing everything off 👎🏻
