I'm sitting downstairs with the monitor on and I hear what sounds like singing. I turn up the monitor and Mr. Ian is singing to himself in his crib. Then he starts talking to himself. I can't really hear what he's saying because the humidifier fan is on in the background, but I'm guessing it's a continuation of his monologue in the car on the way home: "Daddy, where are you? Daddy, I'm coming! Big bus! DA tze-zi! (BIG car) Baby tze-zi! DA bus! Baby bus! Avi avi avi, bunny bunny bunny!" And so on...
