I often tell TJ to do something 30 million times but he won't do it.
Then say "five" to start a countdown - "four, three, two, one." Nothing really happens at one. A time out, possibly.
I usually don't get to 4 before he does it, whatever it is I want him to do.
So, Julia is looking at a book. Count the dogs, I tell her and she says "three, two, one."
