Audio
He really started talking better in September after about five months of speech therapy, at two years and ten months. I have other pieces of audio from earlier that I will include eventually and I continue to gather more recent selections (he is, of course, like any other kid once they start talking, improving by leaps and bounds). These will be forthcoming in later updates.
Addendum (7/20/05): I've accumulated quite the backlog of audio archives that I still have to weed through. I hope to have some for the next update of the site, which will hopefully not be six months again.
8/8/06: Well, I was right; it wasn't six months. It was a year. I haven't really had an opportunity with the audio and have been focusing more on the video we've taken of Noah. Maybe some year I will put some of that up. We'll see.
