Hi guaint -thanks but I have already read that. It's really good. Especially this bit:
"The narcissist also uses favoritism and gossip to poison her childrens' relationships. The scapegoat sees the mother as a creature of caprice and cruelty. As is typical of the privileged, the other children don't see her unfairness and they excuse her abuses. Indeed, they are often recruited by the narcissist to adopt her contemptuous and entitled attitude towards the scapegoat and with her tacit or explicit permission, will inflict further abuse. The scapegoat predictably responds with fury and equal contempt. After her children move on with adult lives, the narcissist makes sure to keep each apprised of the doings of the others, passing on the most discreditable and juicy gossip (as always, disguised as "concern") about the other children, again, in a way that engenders contempt rather than compassion.
