My wife and I worked out a plan: we moved very close to her parents who agreed to watch our children for three days a week. I work M-F days only, no nights, no weekends. My wife works Monday, Wednesday, and Friday. Together we make enough to pays the bills, save a little, and have a bit of fun. The children are taken care of first and foremost.
Sometimes you have to sacrifice to make do for your family by moving, whatever. It's always better to sacrifice money than time from your children. As long as you are making it and saving a little and have a bit for holidays, nothing else really matters. Getting rich should never be the goal.
