I love traveling with my kids individually. We connect differently than when they're with their siblings.

Just 18 summers and 18 spring breaks — that's really all you get when it comes to vacations with the littles (and honestly, those first few don't really count). When you think about it this way, you start to understand how important and precious downtime with them is. Not that they won't want to hang with you when they're in college and launched. But honestly, you can't bet on it.
