I wondered if anyone had some words of wisdom about a friend's child who is borderline bullying my child who is two years younger. She turns a blind eye to a lot of behaviour as her daughter is very challenging but the other day my child was so upset and it turns out this girl had hit him and called him names in front of others and turned them into a gang against him. He has very low self esteem as it is and now I don't want to see them any more but this is very difficult to manage as she wants to do stuff quite often! Feel trapped!
