Let your athlete lead the emotions
As adults, we have more context over game situations—we clearly see when kids make bad plays, miss opportunities, etc. But from the kid’s point of view, especially younger children, they don’t always process the game this way. In other words, it might not be a big deal to them that they’re losing because they’re still having fun. That’s why it’s always best to let the kids lead the emotion. If they’re pumped after a game and in a good mood, roll with it.
