Many families with children separate all around the world. In France, for instance, nearly 200,000 children per year are affected by the divorce of their parents. After divorce, just over seven out of ten children (73%) live only with their mother and visit their father on alternate weekends. This phenomenon begs the question of the short- and long-term fate of these children, particularly in light of research showing that the active involvement of both parents in children’s lives is vital to their development and well-being.
