My daughter always wants to be the first and wins in everything. When someone else is better than her, she becomes a very sore loser. How do I teach her the spirit of sportsmanship?

Hi, I can so relate to your daughter as I was like that in childhood. The best way is to have a casual chat with her that losing is not a bad thing but what matters is to step up. You can show her movies like Pursuit of Happyness :)
