The view that women are better parents than men has shown itself to be true (throughout) history. This is not to say that men are not of importance in child- rearing indeed, they are most necessary if children are to appreciate fully the roles of both sexes. But women have proven themselves superior parents as a result of their (conditioning), their less aggressive natures and their generally better communication skills.
From the time they are little girls, females learn about nurturing. First with dolls and later perhaps with younger brothers and sisters, girls are given the role of carer. Girls see their mothers in the same roles and so it is natural that they (identify) this as a female activity. Boys, in contrast, learn (competitive) roles far removed from what it means to nurture. While boys may dream of (adventures), girls' conditioning means they tend to see the future in terms of raising families.
Girls also appear to be less aggressive than boys. In (adulthood), it is men, not women, who prove to be the aggressors in crime and in war. Obviously, in raising children, a more patient, gentle manner is preferable to a more (aggressive) one. Although there certainly exist gentle men and aggressive women, by and large, females are less likely to resort to violence in attempting to solve problems.
Finally, women tend to be better communicators than men. This is shown is (intelligence) tests, where females, on average, do better in verbal communication than males. Of course, communication is of (utmost) importance in rearing children, as children tend to learn from and adopt the communication styles of their parents.
Thus, while it is all very well to suggest a greater role for men in raising children, let us not forget that women are generally better suited to the parenting role.
