La Loco I don't think the baby knows what it's saying. It's probably repeating no because it's receiving positive attention for doing so. So, five stars!
kingarthur Well, duh! But we keep asking it those sorts of questions because we get a positive stimulus from it as well which will only stop when baby gets bored with it or learns the meaning. Baby talk feedback loop, ho!
The Townleybomb I dunno, you're kind of going out on a limb on this one.
