Intergenerational trauma and subsequent impairment of trauma survivors parenting of their children is explored. How to engage these parents in integrative family and systems treatment (I-FAST) and how to simultaneously help with their parenting impairments and their trauma symptoms is described. Four cases are examined in detail, covering four types of treatment situations. In Cases 1 and 2, helping a trauma survivor parent when they are requesting help for their problem teenagers, but not for their trauma-related difficulties is described. In Case 3, helping a trauma survivor mother focus directly on resolving her trauma symptoms as a method for helping her seriously impaired daughter is described. In Case 4, focusing on serious dissociative symptoms of a mother, which only developed after the successful resolution of her son’s difficulties is described.
