He's on a Roll

This is what Luke has been learning to do recently:





Those videos were taken a couple weeks ago. He's getting much better now. Now he can roll from on his belly to on his back, and vice versa. Up until yesterday he was still having trouble switching between the two, but he seems to have gotten the hang of it now. He still has some trouble going from on his back to on his belly; he rolls onto his arm and it gets stuck, making it harder for him to prop himself up afterward. This usually frustrates him, and then he starts crying after a while.
