Different From Simple Estrangement
Families can become estranged for many reasons, including basic conflicts and misunderstandings. In GAS, the estrangement is the result of one or more persons actively working to turn a grandchild against a grandparent.
Usually this takes the form of blocking grandparents’ access to grandchildren, combined with verbal attacks against the targeted grandparent. Of course, grandparents cannot know what is being said about them out of their presence, but when previously affectionate grandchildren become distant or fearful, that could be a red flag.
