The first day of school is exciting—but it can be scary, too! Meet Rosie, a brand-new student who just happens to have butterflies in her stomach. “Silvestro and Chen take a common figure of speech and transform it, literally, into a lovely expression of a universal experience.” —Kirkus Rosie can’t wait to start kindergarten—she’s had her pencils sharpened and her backpack ready for weeks. But suddenly, on the night before the big day, her tummy hurts. Rosie’s mom reassures her that it’s just butterflies in her belly, and she’ll feel better soon. Much to Rosie’s surprise, when she says hello to a new friend on the bus, a butterfly flies out of her mouth! As the day goes on, Rosie frees all her butterflies, and even helps another shy student let go of hers, too.
