Hi M.- couple of suggestions. First, the cry it out method did not work for me either and I am not a fan, it is cruel. I would just keep going in there and reassuring her. My son went through this and we transitioned him to a toddler bed and that was the ticket. At 16 months she should be okay. My husband and I, at night, would put him to bed, put a gate at his door so if he woke up he wouldn't leave his room if he got out of bed, it also assurred us he would not wander if we didn't hear him right away. The freedom to get up and not be trapped helped. When he did get out of bed we put him back over and over and over again. Eventually he stayed in bed, but he had the freedom to move around if he wanted to. The crib, at some point, becomes like a little cage for an active toddler who wants mommy. In a toddler bed, you can sit on the bed and hug her without pulling her out of bed, you can get closer to her, which is what she wants. Try it, you might be surprised. Good luck
