My dh was against homeschooling originally. He wanted dd7 to go to a private school. We both agreed that the public schools in our state were not an option. He made the tactical error of giving me an ultimatum that if I wanted to homeschool I would have to handle everything related to it. As soon as it was out of his mouth he realized that there was no way he could handle everything related to dd attending school(especially the drive to drop her off and pick her up). He also realized that he did not want the job of getting dd ready in the morning since he has trouble getting himself up and ready in a timely manner.
As a compromise I enrolled dd in Kumon so she would get a limited "school" experience and started teaching her. She is now about 2 years ahead of where she would be if she were in a private school and dh is definitely supportive of homeschooling.
