Given Freudian assumptions about the nature of children and the biological predestination of mothers, it is unthinkable for mothers voluntarily to leave their babies in others' care, without guilt about the baby's well-being and a sense of self-deprivation. Mothers need their babies for their own mental health, and babies need their mothers for their mental health--a reciprocal and symbiotic relationship.

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. Young children become more cooperative with parents who confidently assert the reasons for their demands and enforce reasonable rules. Even if there are a few rough spots, relationships between parents and young children run more smoothly when the parent, rather than the child, is in control.

A healthy newborn has been delivered in a more or less satisfying fashion. The baby is feeding well, has short nails and a clean bottom, and has not drowned. What now?

Not until Freud's writings became popular did descriptions of infants center on relationships with their mothers. The idea that children have feelings of any lasting importance for their development is a very recent invention (or insight if you wish).

Children are just different from one another, especially in temperament. Some are shy, others bold; some active, others quiet; some confident, others less so. Respect for individual differences is in my view the cornerstone of good parent-child relationships.

Fortunately for common sense, psychological research has shown that babies with more than one attachment are less distressed whenmother leaves to go to work. They are more content and playful in the presence of other adults, meaning that they feel secure with people other than Mother.
