My daughter has taken to participating in what I like to call 'cot gymnastics'. In layman's terms she has taken to sleeping in an array of weird and interesting positions. Sideways, diagonally, on her front with her little legs hanging through the bars and my favourite her head at the bottom of the cot, buried in her teddies.
It would seem that her fidgeting and constant movement is not just contained to daylight hours. It's anyone's guess what position she will be in when I go to check on her later. If she was standing on her head it wouldn't surprise me.
