We've conciously made time each day to spend reconnecting, typically about an hour and a half after the kids are settled for bed. Previously, we were living what WWME called the "married singles" lifestyle, where each of us would go do our own thing in the evening, usually not even in the same room. Now, we try to do some of the routine shopping together, leaving S15 in charge of the brood while we slip out, and in the evenings try to be at least in the same room so we can chat as we go about our things if our schedule isn't allowing focused time together.
