Roll Over Beethoven

Two days ago G rolled from his back to his front to play with a toy and Mark. When Mark walked to the other side of the room (excitement over football) G rolled onto his back again, taking his toy with him. Then he rolled to his belly and back again to follow Mark across the room. He kept going and traveled about 6 feet this way. The toy stayed with him as he kept moving it into his intended path. The feat of going belly to back was a new as the invention of rolling to travel!
