A groundbreaking exploration of how fatherhood transforms men’s brains, bodies, health, skills and relationships - showing that men are wired to participate in care, just as women are. 'Saxbe’s deeply researched and entertaining book fills a crucial gap in our understanding' Financial TimesIn recent years men’s attitudes to fatherhood have changed dramatically. But only now are we learning how profoundly fatherhood changes men’s brains and biology – and the effects these changes have on their health, skills, relationships and sense of purpose. In Dad Brain, one of the world’s leading researchers of fatherhood, Darby Saxbe, provides a captivating account of this new science, revealing that:• Fathers’ brains shrink and their testosterone drops• Fathers undergo a host of hormonal changes once thought only to affect women• Fathers can suffer post-partum depression but enjoy better long-term health• Fathers’ style of play makes their kids more resilient• Dads who do more housework are generally happierAbove all, Dad Brain shows that these are all crucial adaptations that enable better parenting but they only come online when fathers invest time into parenthood: the more they do, the more they change for the better. Ultimately it shows a good father is not something you are, it is something you become. ‘A terrific addition to the increasing number of fatherhood books’ New Scientist'Fascinating . . . lucid' The Times‘[An] accessible account of the latest science of fatherhood . . . fun . . . interesting . . . valuable’ Literary Review‘Saxbe wants to debunk the stereotype that parenting does not come naturally to men and . . . takes particular aim at the myth that they “lack the biology for it”’ Sunday Times
