Chrysanthemum by Kevin Henkes

Chrysanthemum is a young mouse who loves her unique name until she is teased about it by her classmates. Her main tormentors are three mice named Jo, Rita, and Victoria, who ridicule her for being named after a flower and point out that her name is so long it barely fits on a name tag. Chrysanthemum expresses her sadness to her parents, who comfort her with her favorite meals and a game of Parcheesi while her father secretly reads a book on child psychology. One day, her class meets the pregnant music teacher named Mrs. Twinkle, who help them with an upcoming musical. Chrysanthemum is assigned to be a daisy, which makes Jo, Rita and Victoria tease her once again. However, Mrs. Twinkle confronts them, and reveals that her first name, Delphinium, is also long and inspired by a flower. The three then apologize, and Chrysanthemum’s confidence in her name is restored. Later, Mrs. Twinkle gives birth to a daughter, whom she also names Chrysanthemum.
