Sam McBratney is the author of the best-selling Guess How Much I Love You and many other books for children. Of this book he says, "People often ask authors where their ideas come from, and often authors say they don't know. But I do know about this one. Once upon a time, my wife and I had three small children — two boys and a girl, just like in the story. And when they were young, we used to tell them a story very like You're All My Favorites." Sam McBratney lives in Northern Ireland.
Anita Jeram is the award-winning author-illustrator of I Love My Little Storybook. She also illustrated Kiss Good Night and other books by Amy Hest, Guess How Much I Love You by Sam McBratney, and many other picture books. Recently, her son asked her which one of the children in their family was the best — himself, his brother, or his sister. She explained they were all equal in her eyes, and he came back with another question: "Okay, then, who's the cleanest?" Anita Jeram says, "There's always one in every family." She lives in Northern Ireland.
