My DS goes to the same holiday club as a boy he used to go to nursery with. They are both 7 now. They have both been going to this club since they started primary school. At first I was pleased about this but recently this other boy seems to be getting quite aggressive. During the last school holiday he got my DS in a headlock & was hitting him on the head. Last week he pushed DS in the face. Yesterday I arrived to pick DS up to find this boy and another kicking footballs at DS whilst he was sat on the floor which resulted in DS crying. Today DS told me that another boy had knocked some cards out of this boy's hands and this boy wrestled the other one to the floor, got on top of him and started hitting him in the face. There have also been a few other instances of not very nice comments made to DS.
Would I be out of line to ask the manager of the club what they are doing about this boy's behaviour? Or am I overreacting??
