It is the extended family and the Body of Christ. In the broader context of the family there is help available. The Bible speaks much of a three-generational model of family, for God is the God of Abraham, Isaac, and Jacob. Grandparents have a crucial role in the raising of children. But so does the Body of Christ.
Older women are to teach the younger women.
Elders are to care for the families in the church and teach them the biblical principles relevant to training children. No parents need be alone. Many so-called experts are not as well qualified as they demand that we should be. Adam Smith never took a course on economics, but his writings have been classics on the subject for a long time. Karl Marx never took a course on economics or political science, yet he has had a profound impact on both those disciplines.
