Don't have kids so I can't comment on that, but I reserve time for fun. I almost without fail reserve friday night as a night out with either my wife or friends doing something that's not related to work/tech/programming. I love programming, sometimes I even want to spend friday night doing it, but none the less it's good for my long term mental health to get away and do something else. I spend a few hours on the weekend learning 'long term' stuff, like math or technology not related to my job. I try to do this in a coffee shop or outdoors so it's a pleasant experience. A little over half the time I eat lunch while wokring but I never work through dinner. That's time for socializing or with friends, even if I have to go back to work.
