I have spent time with many children from all walks of life. Some of them have been facing hardship other than their learning differences. Sometimes they have divorced/divorcing parents. These children fall into two categories:
1. Their parents put the children's wellbeing first and foremost
2. One of the parents is an alienating parent
Children from category 1 recover from their parents' split fairly well. Children from category 2 have ongoing problems.
There is no legislation in place in Australia to stop alienation, yet it is a form of child-abuse. In extreme cases, the alienating parent (usually with a narcissistic personality disorder) succeeds in permanently separating the target parent and child. The consequences are often tragic.
