Madi's sleeping habits

So madi has decided that sleep is not for her. There are days when she doesn't think she needs a nap or needs to go to bed. This particular night she didn't think she needed to go to bed. We had put the kids to bed and had gone downstairs to watch tv. About nine o'clock brady thought he heard something and looked upstairs to find this. She had gotten out of bed but didn't say anything to us, becasue, if she gets out of bed we take away the binki. Instead she decided to sleep at the top of the stairs. She is so stubborn, she gets it from her dad!
