Damien moves a lot.
He scoots down his track on his tummy, but also, especially lately (over the past week or two) has been getting around on his back.
He likes to kick a lot when he is on his back (especially kicking me to get my attention) but sometimes he actually lifts his bottom off of the floor, or pushes off of things to do sort of a "backward scoot" in the supine position.
Hence, putting him on his back to limit his mobility (such as when I don't want him to go anywhere, like for diaper changes) is not exactly all that effective anymore.
Damien is 2 months, 2 weeks old [11 weeks]
