What Is the Theme of "Tales of a Fourth Grade Nothing"?

Judy Blume's 1972 children's novel "Tales of a Fourth Grade Nothing" centers around an older child learning to handle sibling rivalry from his toddler brother, even when something he loves dearly is taken from him. The protagonist in the story is nine-year-old Peter Hatcher.

Peter's brother Farley Hatcher, whom Peter calls "Fudge," is an annoyance to his older brother and gets away with his bad behavior, making Peter feel like a nobody in the family. He is expected to overlook his baby brother's antics and to adjust to all the bedlam Fudge brings into his life. This becomes particularly hard when Fudge swallows Peter's beloved pet turtle. Fudge recovers, but the turtle dies. Peter has to learn how to handle his feelings about the loss of his pet and his brother's role in it.
