Julie Fogliano has spent her entire life reading children's books. Now she stays up way too late writing her own books while eating cereal. She lives in the Hudson Valley with her husband and their three children. They make her very tired, but give her lots of good ideas. So far she has authored And Then It's Spring, for which she won the Ezra Jack Keats Award, If You Want to See a Whale, When Green Becomes Tomatoes, recipient of four starred reviews, and Old Dog Baby Baby with art by Chris Raschka.

Christian Robinson's award-winning books for young readers include Josephine: The Dazzling Life of Josephine Baker, which was a Coretta Scott King Honor Book as well as a Sibert Honor Book, and Harlem's Little Blackbird, which was an NAACP Image Award nominee. His Newbery Medal and Caldecott Honor book Last Stop on Market Street was a New York Times bestseller, and School's First Day of School (written by Adam Rex), has earned seven starred reviews. When's My Birthday? is his second book for Roaring Brook Press.
