Jive,
Your kids are only young once. I suggest you make your son your priority. Kids need as much of your time as possible. Just being with them, doing whatever, IMO, is so much more important than having your wife being able to walk around with a couple of C notes in her pocket.
IME, I quit gigging up until my daughter was about 12. There's just so much to do with your kids that, if you're able, I suggest reducing your gigging to the minimum and spending the extra time with your family. Now I have two grandkids and they get all the support and love that they can handle. Teaching them is a great honor for me as they will carry on for me into the future.
Not only from experience, I have a degree in Child Development and my wife has 2 degrees in the mental health field. She works with families/children. She works with kids who all need love and support to turn their lives around.
Best to you and your family,
Stumbo
