I have 3 kids as well... all young. 8yo, 6yo, 4yo. 10 minutes a day is one thing. 5 hours on a weekend is a big deal. Weekends are the only days I have a large enough chunk of time to brew. For my own sanity, I try to set aside some time every weekend for me to do something. Some weekends I go to the gun range. Others, I go for a hike. And others, maybe I brew. But every time I take "me time" I have to keep in mind that it's going to take away from something else I could be doing. Some of these things I can do with the kids... they love to help brew and I am sure to keep them away from the hot wort, so I let them measure ingredients, or maybe bottle on bottling day. They can join me on my shorter hikes (and we can bring our dog on these too.. bonus). There are times though, that I just need to be in my own head without worrying about anything else. Fortunately for me, my wife is very understanding about it, and she gets her time as well.
