I wish I hadnt just read this before I try to go to bed LOL sorry but I have goosebumps. If she stands and starts walking backward I would get concerned.

Having said that, my DS has done this before. Except he would be standing in his cot, leaning on the rail so only his littl eyes were peering over the edge. Totally silent, scared the hell out of me the first time because I was looking for a sleep bub laying down and saw eyes staring at me.
