Really kid? Just sit already

So I have NO IDEA what I am going to do with this kids while I am trying to watch CC practice baseball... He doesn't sit still. The practice was an hour and Mark and I were beat from chasing him around. He tries to sneak on the field and steal the balls. He doesn't get nor does he accept, that it's CC's turn to practice. And since baseball is his most absolute favorite thing in the whole wide world, I need to come up with something to occupy him.

So far this is all we can come up with....
