It is also easy to lose sight of the fact that once your kids are in their teens, they really start living their own lives much more so than in the past. You don't see that you are going to say goodbye to your days as the family's benevolent dictator, waking up in the morning and declaring "today we go to the museum" (or on a hike, or to the workshop to build something together, or ...) so make the most of those formative years while you are still the sun their world revolves around!
