Exactly this. My grandfather and I often go with his new son (yes, I have an uncle less than half my age) and we'll be watching our players butcher the ball time and time again, then we'll turn to little Michael who's playing with his iPod Touch. My grandfather gets all mad, but I reckon if you can get them to be happy to go to the football when they're young, the rest is easy. Once we get good, then it'll be more interesting, so as long as you can keep them happy about going to the footy (regardless of whether they watch what's going on or not), then the hard part is done.
