Coco has a new way of drawing faces. He makes a circle for the head; two dots for the eyes; then two sides of a triangle for the nose, to which is attached an arc of a circle for the mouth. (I'd post a picture but the camera is in France with Julie.)
When I said, "That's really cool. How did you figure that out?" he answered, "Five-year-olds know a little bit of stuff."
An example of what he knows: "Theo A. says that two plus two is three. But two plus two is one."
There you go.
