Progress staying on "place"

Tucker is suddenly making real progress staying on place. This has been hard for him to learn, but the past few days he will stay there without a correction for up to 15 min. Although there's always something he can see that he wants (even though there are toys on place with him). I think his neck has stretched out a couple inches - he hangs his head off place and tries to reach the item without his feet touching the floor - quite a contortionist. Then he sighs and gives me the big-brown-eye-treatment: "I'm soooo booorrrrred!"
