Trinity,
I Apologize for being so tardy in my response.
DS is in a very small montessori program with about 5 elementary aged students and about 20 preschoolers. He is one of the oldest in the school. This is why he lacks contact with his age peers.
Second, his interests are very broad. We are currently encouraging his desire to learn Chemistry and marine biology with books and some help from a local college Professor. He has an amazing fantasy life full of raptors and dragons that interact with him and each other in a very detailed and involved way. He is currently dictating to me their stories and I'm typing them in to the computer.
Third, I read everything I can find. Hoagies has been a primary source of information as well as SENG. I've read just about everything I can find on the web or in the bookstore.
I'll try to give more details another time.
