The best advice I can give is that you teach your kids to stay away from TVs and videos as much as possible! But you have to teach by example, they have to see you reading, or taking up tennis, or bicycling, restoring furniture, taking music lessons. As for manners, the best way to teach is by example too: insist on saying please, thank you, holding doors for others. I know it’s easier said than done, but there are no shortcuts.
