DS has just started primary (4yo) and is finding it hard to make friends. I have suspected that this is because he doesn't know how to "play" well with others in a unsupervised setting. Today, after an incident in the playground this week, I went along to watch what went on. As I stood, unobserved by the edge of the playground, I saw him hassle other kids, play fight and generally act in a silly way. Most of the others his age were not acting like this. He is actually a really lovely little boy and it breaks my heart to see him being so bad. How do I encourage him to play nicely, and how on earth will he make friends if he carries on acting like an numpty?! Any advice ?
