We started a reward chart. For every night she sleeps in her big girl bed, she gets a sticker. When she fills up each row (which would be a week if she does it every night), she gets a new book. It's been working really well. We didn't have the problem with her sleeping in our bed, it was more about her staying in her big girl bed when we transitioned from the crib. She was also a little bit older, I think a few months after she turned 2, so I am not sure if the chart might be too early or not, but I am sure worth a shot! Good luck!
