Of course, if you have a home business, the picture is much brighter. If there is more than one child, it is definitely a full time commitment. This can't be done at night, especially with small school aged children. You can, however, do some tutoring at night for a little time, or more so, with older or high school kids. But, in general, children need their rest and good nutrition.
Home schooling is mostly a 'day' activity.
If you are doing home schooling for religious reasons, then the choice of curriculum and supplemental materials may be easier for you. It's just hard sometimes to intergrate or separate religious theology and philosophy from the educational concepts of a material world. It is hoped, just the same, that a belief in God would be included in every child's daily life and somehow intergrated into their education. At any rate, no one said that home education was going to be easy anyway. But, it can be a happy and rewarding time for you and your student.
