I'll be watching this thread as well as it also applies to us a little. As others have mentioned, my DS has found some friends among the girls. I have encouraged him to think about games he can share with other boys his age and interests they have in common. He has zero interest in superheroes, which he finds really boring, but he does like sports. We have also asked the teacher to suggest boys that would be a good fit for him friends-wise. Good teachers do often have an idea on this stuff.
