I was at a local attraction today with DS (8) and DD (5). DD was playing with a large xylophone type instrument. A smaller child- I would say around 3/4 came over and tried to pull it out of DDs hand. As I was close by, and could see no other parent, I intervened by holding the stick part firm and saying “No- DD has this right now- once she is done you can have a go”. The child started yelling and trying to bite my hand. Which was ineffective as I moved out the way and blocked the child from both DD, myself and the instrument. A angry mum then came storming across huffing about us not allowing her child to play and took the child elsewhere. I feel she was mostly annoyed at having to get herself up off the bench and parent. Would you have handled this differently?
