I'm possibly getting to that place too, considering options.
Being a teacher's aide is a good option too. Then there's summers and holidays off with your kids etc. The requirements depend on the school/district. Some private schools don't require coursework, they realize experience with kids is valuable. Other districts require some coursework, but it's not much.
Being a school bus driver, providing respite for families with disabled kids (agencies hire for this, it's usually hourly).
Best of luck to you!
