My ds (5 and going in to year 1) is very eager to win everything but afraid of competition, to the extent that he often won't get involved when he might lose. He is able academically and reasonably good physically, so there is no obvious reason he shouldn't take part, but he can get very intense, even about party games, when other children seem much happier just to have a go. Any advice on how to manage this? I'm worried he's going to lose out.
