Ds is in yr1 primary and Ibhave heard from others that him and his friend can be quite mean to other kids. He is fine with other kids one to one but when he is with his best friend it seems it's not always kind to others. I get the impression that his best friends mum is not very welcoming of a chat about it. I have spoken to the school to see if they could be supervised better at playtime. I have repeatedly spoken to DS about it. Any tips on what strategies worked for you?
