A few months ago I'd have said good luck! I hadn't had a night that a kid wasn't in my bed in ages. I have changed that though. You just have to keep putting her in her bed. She's old enough to understand that she needs to sleep in her bed. I had a few bad sleep nights but they both stay in their bed now. When sh comes in imediately take her back to her bed and tuck her back in. If you give in even once you'll be back to square one. Stick with it and she should be in her bed all night in no time. She's much older then my kids that were having the problem so to help her along you could promise her a new toy or a trip to a movie if she stays in her bed every night for a length of time(a week or 10 days). Hope this helps.
