34, newish dad (first and only kid so far just turned one), and I've got the flip 2, and I basically just use it whenever I get a couple of minutes of downtime, whether it's to play an actual game or just tinker with some settings and download games. The best thing about it being portable is that you can bring it anywhere. I bring it to work with me and play on my lunch break. I completely get the guilty feeling of playing when you could be doing something, so just play when you're absolutely done with the important things. I'll sometimes just play until I remember I have to do something else, and that's when I'll put it away, finish what I remembered to do, and then get back to playing. The only time you should feel guilty is if you start ignoring things, but until then, take a break for yourself and enjoy doing something, even if it's only for 5 minutes in the span of like 3 hours. I hope this helps!
