Each era invents its own child. Over the past 500 years, conceptions of the child changed gradually from an ill-formed adult who must be subjugated to society's goals to a precious being who must be protected from unreasonable social demands. Childhood has come to be seen as a special period of life, rather than as a temporary state of no lasting importance for adulthood.

Parents who are cowed by temper tantrums and screaming defiance are only inviting more of the same.

Babies need social interactions with loving adults who talk with them, listen to their babblings, name objects for them, and give them opportunities to explore their worlds.

All in all, the communally reared children of Israel are far from the emotional disasters that psychoanalytic theory predicted. Neither have they been saved from all personality problems, as the founders of the kibbutz movement had hoped when they freed children from their parents. In any reasonable environment, children seem to grow up to be themselves. There is no evidence that communal rearing with stimulating, caring adults is either the ruination or the salvation of children.

Until the Second World War, it was unthinkable for a married woman of the working or middle class to disgrace her husband by working after marriage, because her employment indicated that he was a poor provider
