In this book designed for readers in transition from picture books to chapter books, second grader Freddy is stuck in the middle. Judy Blume’s The One in the Middle is the Green Kangaroo, illustrated by Amy Aitken, sensitively handles the frustrations of a child who feels he is too big to play with his baby sister Ellen, but too little to play with his older brother, Mike. He has to wear Mike’s hand me downs, and share a bedroom, all leaving Freddy feeling a little displaced, with no identifiable merit. The production of a school play seems to hold out hope of distinction for Freddy, but he learns that the play is only for fifth and sixth grade students. This children’s novel ends happily though, when it turns out there is a special part for Freddy after all. The One in the Middle is the Green Kangaroo should speak to young readers perplexed by family dynamics, who are eager to prove themselves.
