For too long, we’ve thought of fathers as little more than sources of authority and economic stability in the lives of their children. Yet cutting-edge studies drawing unexpected links between fathers and children are forcing us to reconsider our assumptions and ask new questions: What changes occur in men when they are “expecting”? Do fathers affect their children’s language development? What are the risks and rewards of being an older-than-average father at the time the child is born? What happens to a father’s hormone levels at every stage of his child’s development, and can a child influence the father’s health? Just how much do fathers matter? In Do Fathers Matter? the award-winning journalist Paul Raeburn overturns the many myths and stereotypes of fatherhood as he examines the latest scientific findings on the parent we’ve often overlooked.
