Consider this - no career gives you as many weeks off as teaching, (and before those of you that want to argue jump in with the "it's not paid time off" argument it's still TIME AWAY FROM WORK). Most civilian gigs (as I call them) give you a few days, (Christmas, New Years), and 2 to 4 weeks off. You work 48 weeks a year. If you are after family time the middle school route where you have a few weekends and evenings but gives you 13 weeks of not having to be at work might give you more time than you think.
If you are happy with music and teaching I would explore those options.
