"K, pay attention to me!"

Eli can say many words and he is starting to even form a few word sentences. But he still loves to "jibber jabber." He will sit there and go on and on in his own made up language telling me this excited and animated story. He even uses his hands and lots of body language. And if I turn away even in the slightest to wipe the counter or fold laundry he yells out, "momma....momma....MOMMA!!!!" He has to have your 100% undivided attention or he gets mad.

He has also started to use the words "K" and "move." When you ask him a question, like; "Do you want an apple?" He would actually reply, "no" or "nose" or "uh huh." (All sounding like no, but he really means yes). But now he replies with "K!" "Eli do you want to clean your room?" "K." "Eli do you want to watch NEMO?" "K." "Eli do you want to take a tubby?" "K!" As for move, when he wants you to go somewhere with him he orders you to "MOVE!!!!" He loves to play "ping pong" so he will come over to me and say, "hand" (then he will grab for my hand), say "ping pong," and if you don't get up and head towards the ping pong table, he shouts "MOVE!!!!" Where does he learn this?
