T.L.
Do you have a night light for her? When my oldest one was around 2 she started to act up and the first night it was so bad she slept with us. We kept the hallway light for awhile and then we told her that we got her a nightlight and she needed to sleep in her room to have it. It was a pretty fun one and that did the trick. Also, I found out that what she was watching on tv was giving her nightmares so we bought some movies special for her and that seemed to help. Good luck! My second one is at that stage now but she is just stubborn.
