Konrad has found his thumb

As a teething four-month-old, Konrad will chew on anything you put within a couple inches of his mouth. Today he sucked on his thumb for several minutes. I tried to get him to take a pacy for the first couple months, but then I gave up...since he doesn't cry much, why should I try to pacify him? We'll see if he remembers this important digit (Lukas was a thumb sucker, but Natalie uses a pacy).
