There is no such thing as co-parenting with a narcissist as they have no concept of teamwork or even cooperation. Perhaps the title would be more accurate if it read, “Parenting In Spite of a Narcissist”. Most often there is little to no “co-parenting” that occurs when your ex-spouse is a narcissist. You spend your time and energy undoing the damage that the narcissist has done to the children. Narcissists see their children as extensions of themselves and are simply objects meant to fulfill the narcissist’s needs. Keep your expectations low for them as parents. They don’t have “normal” maternal or paternal instincts and are incapable of putting their child’s needs first.
