That is terrific news about the new school! My son sounds a lot like yours. As a result of some famil moves, he attended two different preschools, Kindy in one place and then we moved again. What became clear was that he is selective about who he engages with. The second preschool wasn't much fun for him. It was hightly structured and... rather sterile. Well run, though. Some kids really loved it, but it didn't work for him, and there weren't many kids he could relate to. He met some other boys in kindergarten who while not academically similar, enjoyed his sense of humor and had simialr imaginations. Suddenly he started having a grand time with the kids - but he still wandered away to play by himself when he needed some quiet.
All was well, socially, at least.
I hope your sons' new school does the same thing for your DS, and he finds children and teachers to connect with.
