If she can climb out then it is definitely time to transition her to a bed so that she does not get hurt. We went straight to a twin because I didn't like how high the "toddler bed" option was on his crib. Regardless, I think the method should be about the same. He picked out big boy sheets that he liked and got him a bed rail so he didn't fall out. It took us 2-3 nights of consistently moving him back to his bed before he just stayed there on his own. At bedtime we started by sitting with him for a minute, then moving closer and closer to the door over the course of 4-5 minutes, maybe. He got up in the middle of the night a couple of times, but we just put him back and did the same routine again. He always comes into our room to crawl into bed now, but as long as it is after 5 am we just let him stay because it means we get at least a little more sleep.
