He's rolling, rolling, rolling.......

Well here he is the rolling boy. He rolled over the first time 2 weeks ago, and then really didn't seem interested. Now this week this is all he's doing. I can't leave him alone on the activity mat anymore. He gets himself over, lifts he head and looks around, and then starts screaming when he realizes he can't get back over. In the pic. I got him looking up and checking out the world, but I was there to turn him back before the tears started flowing.
