Corbins new tricks

So Corbin seems to be doing something new every week. He has started sitting up and making raspberries and grabbing at things more. The last several weeks he has been rolling over to his back when we give him tummy time and we finally caught him on tape. Here are two pictures from this week and also a video of him rolling over. He also seems to like bath time now and last night he was kicking and splashing for 20 minutes.
