I'd say for us the biggest concerns are the social ones. We don't have a neighborhood of kids, and left to his own devices, DS would stay indoors all day. He does like to play with other kids, but doesn't have that much opportunity to do so. That said, he does have a small group of boys he likes in his class, but all year has only had two playdates, due to the other moms' schedules, the kids schedules, and whatever other reason. I think most of the other kids live in neighborhoods where there are lots of kids so their parents don't really bother with playdates that require scheduling. To DH's credit, he has asked if maybe we should move, as DS is missing out on his childhood. And it was DH who suggested homeschooling so that at least DS would be happy. I can't tell you how huge a turnaround this is in DH's thinking...
