Don't teach your kids programming. Answer their questions when they have them, stop them when they're doing something obviously stupid (like too many hours on the computer, staying up too late, punching/yelling at the computer, that sorta stuff), but do not actively participate. Let them have their fun. Above all, do not get them a personal computer that is located in their own room.

In other words, be a parent, not a friend or, even worse, a colleague.
