We have a problem with one kid on our small estate and our children, they are all 9/10. When this one particular child is not out there are no issues, as soon as they are on the scene we have my children being ganged up by the rest of the kids. This afternoon this one kid has been climbing on my wall to shout abuse at my children playing in the garden and then this afternoon shouting at them at the front window when they were inside. I have this on doorbell camera. I went out and told them to clear off but I can't put up with a whole summer of this. My children have the right to play out too and certainly in their own house without being bothered. I want to go and speak to the parents but my OH says not to escalate and let it blow over but its been months of this.
