Oh, and I forgot the other thing that actually concerns me as well. While he cannot communicate basic needs and wants, he knows all of his alphabet (letters and the sounds they make) and points out letters everywhere. If we are reading a story, he rarely listens, but when he does come and sit, he will be pointing out letters instead of listening to the story. Now he is starting to learn numbers and shapes as well. Parents are thrilled and while I agree that this is amazing, it concerns me that he is able to do this before actual communication.
