Fascinating reading. We have two school age children, and two who are not yet school aged. We would like to home school, but have the same concern others here have articulated (and other HN posters have answered, partially) regarding socialization.
One concern I have is that an oft-given solution to socialization is "church," but we are not religious and do not plan to become so. This limits options somewhat, and also makes us unlike (our perception of) other home-school families.
Would be glad to hear other suggestions from others who might have had this experience (i.e., being non-religious homeschoolers).
