THE HEART-STOPPER

One of Tobin's favorite things to do is to lean his shins against something while standing up. Once his legs are wedged up against whatever, he starts bouncing and flailing his arms and gigiling like a crazy person.
The part that gets us, is he likes to go up about 5 or 6 stairs and then do the little crazy dance. We of course go racing over, and he in turn makes a break up the rest of the stairs. He never falls, but how long can that last?
Ah, the experience that is raising boys.
