Although fears are commonly expressed for the health of Western society, it is still fortunately true to say that the majority (albeit a shrinking majority) of our children grow up in reasonably stable families where they receive care which is 'good enough' from both parents.1 Developmental psychology is sufficiently advanced for us to know that such children are likely to enjoy mental health in that they are free of incapacitating neurotic symptoms, and that they tend to become secure, self-reliant adults who display social maturity through their ability to be helpful and co-operative with others.
