Here is a long (ish) video clip of me "spying" on him during one such loooooonngggg quiet spell. I thought you might enjoy. It gets more interesting around 45 seconds or so, if you want to skip ahead. Also, I really have no idea what he is saying. Most of it is jiberish with a few "real words" peppered in.
And no, that is not his bedroom. He is still camped out in the office in his pac'n'play because his room is ripped apart from the mold and water leak upstairs. We are waiting as our landlord and the upstairs neighbors argue over who is responsible to pay for fixing it....something tells me it may be a while before Caleb's room is liveable again.
