As a healthy, energetic member of the baby-boom generation, Ian Haysom did not consider himself a typical granddad. He was too cool, too active, and too young (well, young at heart) for such a role. But after retiring, Ian knew there was no going back. Before long, this grandfather of three was discussing the subtleties of ear hair growth with a toddler, reading the same bedtime story on a loop, perfecting the art of the underduck, and beaming with pride as his three-year-old granddaughter sang along to the Beatles. Grandfathered is Ian's hilarious, heart-warming tribute to his grandkids and a joyful exploration of the exhausting, entertaining, and endlessly rewarding role of the twenty-first-century grandparent.
