Celebrate the special bond between grandpas and grandchildren in this delightful New York Times bestseller that puts the kids in charge! The perfect gift for Father’s Day, Grandparent’s Day, and any day shared with Grandpa!

Here’s everything a kid needs to know to spend a fun-filled day with grandpa! Written in a how-to style, the narrator gives important tips for “babysitting” a grandpa, including what to eat for snack (anything dipped in ketchup, ice cream topped with cookies, cookies topped with ice cream) what to do on a walk (find lizards and dandelion puffs, be on the lookout for puddles and sprinklers), and how to play with a grandpa (build a pirate cave, put on a scary play).
