Here are the latest new things: Theo spent a lot of time today humming. It would start with an open mouth, but then he’d close it and the sound came out as HUH-mmmmmmmm.
The other new thing is that I’m pretty sure I saw him looking at his own hands. Daddy had propped him up in the Bumbo while we unpacked after our trip today, and the little man had his hands resting on the chair bit that comes up between his legs. He was looking down as he had his hand palm down, fingers relaxed. Then he looked at the other hand. This is the first time I noticed him noticing his own hands.
