[REBROADCAST] For most of us, the bickering and battling with our brothers and sisters when we were children become amusing pieces of our family history. But for others, unresolved hurts and jealousies accompany us into adulthood and have a lasting influence on all our relationships — particularly those with our families. How do our earliest relationships — those with our brothers and sisters — become toxic in adulthood? Why is it important to resolve them and how can we do it? Psychotherapist JEANNE SAFER has been working with adults and their siblings for many years and she’s detailed her experiences and her suggestions in her book, “Cain’s Legacy: Liberating Siblings from a Lifetime of Rage, Shame, Secrecy and Regret.” Marty talked to her last year about how to heal those childhood wounds.
