Complex Thought

I made an earlier post about how Kole knows many words but not many multi-word thoughts. We've been drilling him on things like "milk - please" when he wants milk. He knows milk and please, but has yet to connect the two, no matter how much we prompt. Same with "crackers - please" and so on. It's one word, then a short time later, the other.
Tonight he finally figured something out and made a connection. His first complex communication is a little payback to his mother, since his first word was "Da Da", and at least a good month or two before he said "Ma Ma".
Tonight's two-word thought while being put to bed: "Nite-nite, Ma Ma".
