Ever wonder why rationality and compassion seem to go out the window when dealing with your partner? A couples therapist and psychiatrist explains it all in this revelatory book about the divide between our adult and toddler brains. Too often, conflict in intimate relationships reactivates our least-regulated "toddler" side, bringing out the instinct to assert our own will. Drawing upon decades of experience in working with troubled marriages, Dr. Stosny shows how to overcome these destructive impulses and nurture a more loving attitude.
