What do you call your grandparents? Silly Yaya is a children's picture book written for children who do not call their grandparents the traditional grandma and grandpa. Instead, Silly Yaya tells the story of why "Each one (grandparent) needs their own special name. From family to family, they are not always the same." Explore the book with your child or grandchild to see if the names they call their grandparents are listed in the book. Find the special spot at the end that makes Silly Yaya a Keepsake Book.
