Good news: DS2 was really trying so hard to play with the other children on the camp site this weekend. He kept running up to them and standing there laughing and smiling. He even gave a ball back to a boy who asked for it. I probably should have intervened a bit to help him join in more effectively - the other kids were obviously a bit nonplussed because he wouldn't reply to them - but I just thought I'd abandon the helicopter parent bit for once and watch from the sidelines. And there was a Dad playing who (I think) sussed out that DS2 had SN and was giving him the ball and encouraging him to kick it, and holding off the other kids to give DS time - so thank you, Dad, whoever you were!
