A grandfather rabbit celebrates the birth of a new baby bunny and recounts the many adventures they will have. Grandpa—complete with bushy, white brows and gray, furry coat—is delighted when his grandbunny is born. Sweet prose follows the cotton-tailed duo. “Life is much better / with you, little one, / cutie pah-tootie, / my bundle of fun.” They fly kites together, tell jokes, and burrow together in the ground. A large cast of woodland creatures scampers through the pages to watch the two bunnies frolic and play. Soft autumnal hues and piles of crunchy leaves warm this sentimental ode. Not tipping to saccharine too much, Grandpa gives wise words of advice: “Be brave and take chances, / have fun and enjoy, / each moment, my love, / my pride, and my joy.” As with the previous works by this author-and-illustrator team (Grandma Loves You, 2013 and Grandma’s Christmas Wish, 2014), a special section to write a letter from grandpa to grandchild and include a photo is appended in the back. A beloved grandparent gift purchase to be sure but also a toddler-friendly inclusion to an intergenerational storytime. (Picture book. 2-4)
