The first question people will ask is, what are your (and your husband's) eventual goals for the family? If you want to save enough to have one or both parents home with kids, the answers will be different from those if you want to have sufficient FU money for disaster insulation, but don't care about early retirement.
That said, my answer sort of depends on where you are financially. I am not a "hard-core to the finish line Mustachian;" personally my answers vary with circumstances. For me...
If you are accumulating consumer debt rather than paying it (or are so tight monthly that you're in danger of it), have debt in collections, or are unemployed without a good-size stash--hard-core mustachianism and no whining--beans and rice, free library DVDs, the cheapest cell phone you can find (and, oh yeah, put that extra time you have into bringing in income, whether it's a side hustle or a better job). My recollection is that's not your situation.
If you are paying down consumer debt or a car loan, and building your emergency/FU fund (some people would also include paying student loans in this category)--still fairly hard-core Mustachianism. Maybe you have Netflix, or go out for the occasional coffee, or browse thrift stores for cute sweaters, but you may also continue to work one afternoon a week at the second retail job, etc. You stick with the job that brings in a solid income even if something else looks tempting (although of course you can always look around to see if there's something better with commensurate or increased pay).
If you are paying down the mortgage or accumulating to retire, and have a solid FU fund, it really just depends on your long-term goals and we can't really answer that for you. How much do you want retirement versus job satisfaction versus consumer goods and experiences? (There's not a right answer to this...this board is going to have a natural tilt toward people who want out of the workforce, but there are plenty of people who have a vocation and feel the best use of their life is to work at it, especially when the FU fund takes economics out of the equation.)
Of course some people will choose to stick with hard-core Mustachianism throughout the process and hit their goals much quicker.
Good luck with the decision!
Oh right, and personally I tend to be a "mitigated risk" person. I do take risks (multiple cross-country moves, once without a job) but I try to make sure I have a safety net in place first. For instance, the time I moved without a job, I had free housing with family while I was looking, and lived super cheap in the meantime.
