"doh on!"

This evening when I put E to bed...

E (pointing at the hallway): "On!"
Me: "Do you want the light on?"
E (nodding head): "On!"

I get up and turn on the light and then close his door almost all the way, then go back to say goodnight.

E: "On!"
Me: "The light is on."
E (pointing to the door): "Doh on!"
Me: "Door open? You want the door open?"

He used his words! And put two of them together on his own without any prompting! Yes!!!! YOU ROCK, E!
