false

Khan has already learned the meaning of "No.". I've said it- sometimes shouted it- pretty much constantly since he achieved mobility. Fingers in a socket: "No." Lamp cord: "No." Dumping out cat's food bowl: "No." Rolling over during diaper change: "No no no no no!".

One magical day, Khan went for the Nintendo Wii. I snapped, "No!"

And...he stopped. He froze, turned, and looked at me.

Then he grinned and lunged for it.

(Wiis are surprisingly hardy despite their small size, if you want to know.)

So he knows what "No." means, he just...chooses not to obey it. It's a start. I guess.

But from the way he giggles when I snatch him away from whatever mortal danger he's approaching, I think we still have a long way to go.
