My DS is 6 and is a terrible loser. He plays on a grass roots football team, and he’s good, but he gets very upset if his team are losing. He starts sobbing, will stop playing and refuse to join back in. He is very competitive by nature and has a short fuse naturally so it’s not surprising, but I’m finding it so hard to help him cope. I often do role play with his teddies, where they’ll race or play a football match and one will lose, I model gracious losing, we’ve read lots of feelings books (he has big feelings anyway).
