All great advice. The only thing I would add again would be to get someone else to train your son. I taught both my son and daughter, sometimes with it being dad on the end of the buddy cord the kids would not take some things seriously. Completely normal I think with Dad/child training relationships. Dad's also can be more demanding then they would be for a stranger. If there is someone you trust at the field to train your son and will do it in a fun way then I would give that idea some thought. If there isn't then train him yourself with all the great advice already given. Good luck
