Rob found a program through the school system that evaluates kids for free. It seems to be designed for the diagnosis of learning disabilities, but they also do speech analysis, so Rob brought him in.
They found Jay thoroughly delightful and said his vocabulary is very advanced (apparently "suddenly" isn't a word typically used by four-year olds). They also determined that his intonation is at the proper stage for his age. However, one lady commented that he had a "little southern twang."
So now we wonder if that is why his Yankee parents don't always understand him!
