He has never crawled and perfected the art of bum shuffling. He can walk round the furniture really quickly so am sure he'll take off on his own soon but if I lie him on his back, he's like a tortoise. He can't roll over or get out of that position. Great if I want him to stay put but he just doesn't like being on his tummy. What does worry me is that once he starts walking, how is he going to recover from the inevitable falls? Any thoughts or comments appreciated.
