Lucas loves to say NO. But we don't think he quite knows what it means. Such as when you ask him, Lucas, would you like to play with your blocks? and he says "NO!" but then brings the blocks over to play with anyways. I think he just likes the shock effect he gets sometimes.
He also said please last night without being prompted by me. He brought his blocks over and shoved them on my lap, for me to open the container. And before I could say anything, he smiles angelically and says "Pees!?".
yay!
