Two days ago, Grant graduated from tentative half steps to enthusiastically walking. He can take 3 or 4 steps in a controlled forward fall until his momentum overtakes his feet and he dives the last few inches into our waiting arms. And then he looks up at us and claps and claps, pleased as all get out that we are pleased. Sometimes he stands, a wobbly monolith, considering his move, and suddenly folds in half and sits, a feat he suggests to us deserves more clapping and cheers. And so we do.
