Carter's Milestones - Rolling Over

Carter is now rolling from his back to his tummy! When I went to get him from his nap this morning I was shocked to find him on his tummy looking at me through the bars on his crib! I have no idea how he managed to turn over, even swaddled! Later on his mat, he rolled over again from his back to his tummy! He seemed so determined to do it and happy when he did. It is so exciting to see him doing new things. I will try to get it on video.
