Since you are asking this question, I feel that you have already made the decision to provide your child with a home school experience. You know your child best and should feel comfortable with this decision. There are alternatives to actually educating your children other than in your home and by you, but they will depend on the area that you live in. Several churches offer educational programs that you may want to check into, and some home schooling parents welcome additional students. If possible, you may want to provide instruction yourself.
I've included a link to education.com Find a School. You may be able to locate a home school using this feature.
