Most children who attend a classroom school private or government, Christian or secular, classical or traditional are pulled toward their peers. They bond with their peers, and they are drawn away from their parents. The authority of the parents is undermined subtly and perhaps quite unintentionally, but nevertheless unavoidably. Oh, sure, the child stills loves mommy and daddy. But the heart, the affections, the attentions, the very life of the child becomes bound up with his peers.
Parents lose the hearts of their children.
If you had asked us in 1985 why we homeschooled our children, we would have responded that we wanted our kids to get a good education. We wanted them to learn Latin and Greek. Today, we would tell you we Homeschool because we don't want our kids to be socially bonded to their peer group. We want to keep the hearts of our children where they ought to be, with their parents, until it is time for them to marry and to leave home. We parents need the sanctification which comes from teaching our children, and our children need the same from us.
