Future Gymnast?

Carter came running in the door the other day, yelling "red alert, red alert...Caleb's in trouble!" I bolted out the backdoor to check things out, and I see Caleb hanging on the beam across the top of the swingset...as I run to help him, he starts lifting himself up and scooting across the beam to get to the platform where he can get down. I wasn't sure whether to be scared or impressed. So, now, pretty much every time he goes outside to play, he climbs back up there and works his way back and forth across the beam. The pictures give you an idea of what I see out my window...I think I have a little gymnast on my hands!
