Daley Ponderings

In situations where it's fun to count down (jumping, etc.) Jonathan will now say, "one... two..." He doesn't seem to want to say three, but the first two are very clear.
We were playing outside today, on our furniture cart, riding it down the very gentle incline of our "yard." When I pushed off, I'd say, "one two three go!" A couple of times, he said it himself, "one two" and off we went!
