Jake is almost four months old now, and when he gets hungry, he snacks on the most available thing to him, his hand. But for the first couple of months of his life, he did one of the most optimistic things imaginable. He would wake up from a nap, decide he was hungry, and just open his mouth and turn his head repeatedly from side to side, Stevie Wonder-style, waiting for some food to drop in.
THAT'S optimism. (But it was well-founded, I guess, because some food always did drop in, just like he expected.)
