My eldest children, 12 and 10, are so competitive, in general but especially with each other. Not in a way that feels healthy/going to spur them on to achieving stuff type of competitive.
We can't play family board games or card games without tears or fighting. The eldest in particular dislikes being beaten I think he feels it has upset the natural order of things if he's not best cos he's been used to being fastest, strongest etc. it makes him awful to play with but also means he gets really frustrated and upset about things like his younger brother doing better in a music exam or getting further in a video game.
I am very conflict avoidant and tend to avoid competition because I dislike external pressure, dislike failure, dislike the sense of being in conflict even in a game. So I recognise I'm maybe not best places to handle this...but how can i help them deal better with competitons, and have a more normal/healthy reaction to losing?
