Kids would be 13, 8, 5
I think I would have to find something flexible, maybe 7am- 3pm. Bus drop off for little ones is 2:45, and for middle school is 3:50.
DH doesn't mind being sole provider, but would be willing to see how it goes with me working. I have done contract work at various times (10 hours a week or so) while having the kids home, but not in the past two years.
If I did this I would have strict rules: frugal on the work wardrobe, no eating out or convenience foods (maybe would require simpler meals and weekend prep work), no extra work expenses. Entire pay would go towards 401k max, taxes, savings. I don't want lifestyle inflation.
Of course summer would be another issue.....
