Picked on or not able to participate is part of the same grouping that goes on in schools. For the most part is little to do with how much they are enabled or not to fit in.

Before being a parent I'd have inclined to agree with GP. The experience of seeing my kids progress, and their differing experience, through school leaves me believing it's nearly all down to personality. That of course is far harder for parents to influence. Course a kid with a sensitive disposition might well blame the lack of the right things as the reason to feel an outsider.

The one certainty is parenting ain't easy. :)
