My little boy is learning how to response

He will be ONE in 3 weeks time, and his birthday celebration is in 2 weeks time. How time flies. From a crying infant to a walking, blabbing baby.

Ernest has learned to response to words and actions:
1) When u say ball ball, if he is not holding to one, he will do the throw action and say a mispronounced 'throw' in chinese. If he's holding onto one, then he will raise it up to show it to you.

2) When u say sit, and hit a spot, he will walk over to roughly that spot and sit.

3) When u say lie down, and hit a spot, he will walk over to that spot and lie down, face down.

That's all I can remember or know.... will update if anything else.
