I'm a single parent homeschooling, and I'm only able to make it work because the situation is right. I would say a single working parent needs two or more of the following:

- Flexible job hours;

- A big homeschooler community, offering lots of kid-swap and co-op classes;

- Plenty of money to hire as much help as you need;

- Relatives who are local and eager to help with childcare.
