Since he is wrestling for Tongie, the first thing you need to teach him is to give wet willies to Clayton Himple and Asher Huseman....ha!
Seriously, just be positive, make it fun and focus on learning technique. Don't worry about the winning and losing, that will come soon enough. The Tongie team is a great group of folks and Coach Goebel does a great job with the kids!
Good luck and have fun.
