Baby Crib Problems😐

So our 6 month old has been sleeping in her crib every night and for every nap since Sunday.(3 Step Sleel Solution ala baby boot camp😅) She is getting used to being in her crib a lot but will sometimes wake due to her foot being caught in between the bars. I know I can't use bumpers yet but is there any solution to this? It happened twice last night, sleep moves around sooo much! TIA
