Last night, Vinny had an amazing breakthrough. I put him on his back on a blanket down on the floor, and he began rolling around spontaneously!
Every other time he's rolled, it's been pretty much coerced. We'd put him on his tummy, he'd hate it, and roll over to his back after a lot of complaining and hurt feelings. But last night, he was a rolling champ! He rolled himself from his back to his tummy, hung out there for a while, and then rolled back to his back, without complaining, without getting upset or feeling hurt. He did it several times, too. It was amazing! He stayed in that classic baby pose (on the tummy, head up) for several minutes, smiling and giggling. And when he'd had enough, he rolled back over.
