Roll over

Jesse started rolling from his back to his tummy less than a week ago, and already he makes it look so easy. Someone told me it's harder for babies to roll from back to tummy and usually they go from tummy to back first. Jesse hasn't gone tummy to back yet, but his little legs are moving and kicking so hard he scoots himself forward on his tummy. His arms just haven't caught up to coordinating with the legs yet. We will soon have a crawler.
