To chime in with a slightly related story on this.
Living in Japan has sort of de-sensitized (is that even a word???) to how retentive some Americans are with alcohol. Here, it's just another fact of life. If a person gets drunk every night with his co-workers, he doesn't have a drinking problem, but instead he is considered a great socializer. I've been on trains at 6:00am in the morning heading to Kyoto (about 100 miles away) and had people behind me cracking open a brew.
I'm amazed at how uptight America is with alcohol every time I go back to the states. I'm nearly 30 years old and I ALWAYS get carded when buying beer. On my last visit I bought a local beer at the corner store, was gonna walk to my parents' home with it, about a 5 minute walk, crack it open right on the front step and enjoy summer breezes and great beer. The lady at the counter was like "Do you want a bag for that?" And I was like..."huh? NO! There's no shame in drinking great beer." Her reply was "Amen to that!"
Anyway, my little cultural rant on that. Spending any time with your kid, as long as you are not endangering them, is the best time to me. I consider brewing to be like cooking and showing kids the ropes in the kitchen is one of the biggest favors you can do them in life. Brew on!
