Good luck! That is wonderful that your ds will have seven other kids from the other family to give him a social group right off the bat.

What online math tutor are you using, if you don't mind my asking? (pm if you'd rather and are willing to share.) I have been tutoring a dear friend's child in math this year b/c she is getting to the point with math where my friend doesn't feel able to teach it. I may not be available to do so next year as much as she would like/need, though, and I am trying to pass on other ideas for her as well.
