Can I suggest that you call your state offices and find out if there is any respite care funds available?
In Oklahoma they used to come through OASIS but then the state took them over and of course that made it much more complicated and took longer for the checks to get to the people that watched the kids for us.
We got $300 every 4 months or $400 every 3 months. I simply can't remember which for sure.
We "hired" a care giver when we needed someone to watch our grand kids. There is also a division that is specifically funded and for families with special needs children. When that caregiver was done we put down how many hours they'd watched the kids and filled in the amount we wanted them to have out of our funds. Then that person signed the bottom and put their information in the appropriate places.
Then we would mail the form in. In a few days, when OASIS handled it, that person would get a check in the mail for that amount. When the state took it over it was a couple of weeks or longer. But they eventually got the check for the full amount.
They were responsible for paying their own taxes or anything they needed to do. They were contract labor and they were paid the full amount owed, any amount within our funds that is.
If we paid them the full amount we had in there then we weren't able to pay anyone else any money.
We paid a L. from church to watch our boy every Wednesday so I could go volunteer, my husband couldn't keep up with the boy and this L. was amazing with him. We paid her $20 or $30 for 4 hours depending on if we took food for them or not. At her home.
When we took both grand kids over we paid her $30 or $40, again, if we took food with the kids and brought enough for her to eat too we paid her less.
Anyway, there should be funding available for you to have where you can get some respite care for all the kids.
