The bond between a grandpa and his grandchildren can be so utterly unique and special. Grandpas can be funny, do tricky tricks, know where to find the best treats, tell the best stories, know lots of interesting facts or have snuggly laps for sitting in. They can like fishing or golfing or basketball or music. Whatever your grandpa is like, we'd bet he's pretty special. These are some of our favorite books to celebrate grandpa's and how amazing they are.
