Why does your schedule prevent you from working 8 to 5 every day? Is it child related? If the only options are the 8 to 5 type, don't let that stop you from looking and applying. There are ways to work around the child care challenges.
I work 9:30 to 6:30 most days. It's not ideal, but I am here in the morning to get the kids ready for school, make their lunches and get them on the bus. The kids to go to an afterschool program, and my husband picks them up. So it is doable.
I teach at a university, so I don't have all the same days off that our kids do, but I do have the summers off and a break at Christmas. Have you considered looking for a job at a local school? There are lots of jobs, and many would allow you to have most of the same days off that your kids have as well as summers off.
If you really want to stay home, you could consider opening your own daycare.
