This smile is a gas

Allison took this quick snap of Tobin smiling the other day. Everyone we talk to seems to say that at three weeks old, it's probably just gas. But then, not everyone has such a strong genetic disposition for wry humor and knowing grins. Me? I think he knows more than he's letting on. Maybe he's smiling at his gas and the reactions he's about to generate with it. There's just too much evidence in this picture for me to chalk it up to gas alone.
