Well Rubie has been rolling back to front for a few days now. I'm forever going and turning her back when she has had enough because she can't roll front to back. Today I left her for about 30 seconds when I went to get her bottle and I heard a bang and a cry. She had somehow managed to get from the middle of the living room to the edge and had banged her head on the tv unit!!! How she did it I will never know, she moved about 3 feet!!!
