Most parents will agree: You've got to get away from the kids occasionally. That's why my wife and I indulge in "date night" once a week. We have a wonderfully reliable, and just plain wonderful, babysitter who spends a couple hours with the little ones while we're away having dinner and just catching our breath together. It's a highlight of the week for Guitar Dad.
A particularly wise colleague once told me that your family commitments must always start with your spouse. When you get that relationship right, then your relationships with your children, and with all family members for that matter, fall right into place. For me, that advice holds absolutely true. To make sure your marriage is a well-oiled machine, don't underestimate the value of leaving the kids behind once in a while. Or in our case, once a week. Every week.
