My name is Joan Friedman. I'm a psychotherapist, a twin specialist and an author. I've written a book called, "Emotionally Healthy Twins." It's a guidebook for parents of twins. And I'm also finishing my second book called, "My Twin, Myself," which addresses the challenges that adult twins face as they mature. I'm the mother of five adult children, ranging in age from 30 years to 22. I've three boys and two girls. My last two were fraternal twin boys and that really peaked my interest in becoming a twin expert, and given that I'm an identical twin myself, I've devoted and committed myself to many, many years of educating and helping people raise twins. I credit my husband for having a very large family, which has been wonderful, raising five unique individuals and we've somehow managed with a quirky combination of empathy and control.
