I have two early primary age DS. Neither DH or I have any interest in football (watching or playing), as a result football has never been any part of their lives. I discovered recently that the oldest (7) doesn’t even know the basic vocabulary of football (to score a goal etc). They are active in other ways but never kick a ball around (and don’t do other team sports other than at school).
I worry a bit that we’re depriving them of something which is almost a basic life skill, especially for boys.
YABU - yes they should at least have basic footballing skills
YANBU - just let them run and climb trees and the things they already enjoy
