One, Two, Grandpa Loves You: A Picture Book (Hardcover) (ISBN-13: 9781419765087)

Shelly Becker is the author of One, Two, Grandma Loves You, which School Library Journal called "a pure, cadenced classic" in a starred review. Her other books include Even Superheroes Get Scared, Even Superheroes Make Mistakes, Even Superheroes Have Bad Days (a 2018 Blue Spruce Award Nominee that Kirkus Reviews called "an action-packed romp"), and Mine! Mine! Mine!, which has been included on many Top Five and Top Ten lists of books that teach the concept of sharing. Becker lives in Toronto, far away from her three wonderful grandchildren, who live in New Jersey. When they can't be together in person, they keep in touch by speaking on the phone and sending plenty of pictures and videos.
