The Female Narcissist and Her Children
The prime rule of narcissism: the narcissist uses anything available to obtain his (or her) Narcissistic Supply.
Children happen to be more attached to the female narcissist because women are still the primary caregivers and the ones who give birth. It is easier for a woman to think of her children as her extensions because they once indeed were her physical extensions and because her on-going interaction with them is both more intensive and more extensive.
This means that the narcissistic woman fights to maintain her most reliable source of supply: her children. Through insidious indoctrination, guilt formation, emotional extortion, deprivation and other psychological mechanisms, she tries to induce in them a dependence, which cannot be easily unraveled.
