If you haven’t seen this article, it’s a very good analysis by a psychiatrist regarding what Parental Alienation Syndrome really is.

If you don’t believe PAS exists, or you’re not sure if the Dad you’re talking to is telling the truth about what’s happening to him and his kids, maybe this is a good place to start. This is very, very real.
