2 Small tidbits:
Anytime we're watching TV, or a movie (and there's been FAR too much of that around here recently), and the music gets dark / slow / ominous Jack says:
"Something bad's gonna happen!" And sometimes adds "A monster is coming!"
Sometimes I haven't even noticed the change in tone, but Jack senses it immediately, enough to verbilize it. Very intuitive.
And when my boy needs to leave his food to go to the potty, he says some variation on this:
"I have to go pee pee. Don't touch my banana!" This morning he said "I have to go pee pee. Nobody don't touch my cereal!"
He's definitely a Wagner.
