Check him out:

This is the first time Finn has ever walked with his push toy, and he did it completely spontaneously, all on his own. I've tried standing him up behind it, and he's always just firmly refused by collapsing his legs. But look at him go now! Unfortunately, I wasn't home this morning during the excitement, but my fabulous eldest son, Kevin, was quick to grab his video camera to record the procession. And Finn was kind enough to show me his new trick when I got home.

It's funny . . . this always happens: just when I think he's never going to do something, he goes and does it, the little rascal.
