Book excerpt: Dr. Warshak's thoughtful, commonsense approach questions the practice of routinely awarding custody to mothers and shows why children often fare best in the care of the same-sex parent. In conventional custody arrangements, mothers are overburdened, fathers are reduced to a superficial presence in their children's lives, and children experience a deterioration in their relationship with each parent. Dr. Warshak shows why we have no grounds for discriminating against.
