When I was mid-40s and my kids were 10-14 I stopped working for a while. I was very burnt out and tired from balancing work and family. I really needed the break.
For the first year or 2 I mostly improved my skills in things that interested me and that would help me become a successful freelancer.
I did a couple of volunteer projects for no fee to give me a portfolio and experience. I did an evening class and attended some cheap local conferences.
I also just did all the other home stuff more slowly, went to the gym, got a dog, saw friends etc.
That time off gave me the mental space to decide what to do next. It helped me get over the burnout. I really enjoyed the time I got to spend with my kids, and help them through some tough times.
Since then I've gradually increased my freelancing so that I now earn a good income but also have the flexibility to be there when my kids or friends need me. I still have some job satisfaction and the knowledge that I could go out to work again if necessary.
My oldest is now at college and I don't want her graduating with massive debt, so much of my income goes to her college costs. I'm assuming I'll do that for my younger two.
What's left I put away in a private pension.
Not sure if that answered your question, but your situation really resonated with me.
