No way to pull them out now and possibly homeschool? It can be much cheaper than private schools. And spending one on one time educating your own children can bring quite a bond that will instill more than just facts and knowledge.
Unfortunately, our daughter was not a good student. She would make an awful teacher. If I was older and retired, I would do it, but I'm not, and I have to work, so that won't work. I have met several kids that have been taught at home. I am very impressed.
