Back to tummy

Over this past weekend, Nathan finally learned how to roll from on his back to tummy. All the baby books that I have read say that baby's usually learn how to roll from tummy to back first. Heh heh...he's backwards.
"Your baby may be able to kick himself over, from his tummy to his back, as early as age 2 to 3 months. It may take him until he's about 5 or 6 months to flip from back to front, though, because he needs stronger neck and arm muscles for that maneuver."
It was funny to watch (and hear). I was napping beside him, and then I woke up to him grunting and making funny noises. He was on his side trying to get that arm out of the way so that he can flip to his tummy.
