When a little girl wakes up on the first day of school, the butterflies in her stomach feel positively giant-sized! She really wants her mom to stay with her, on this first day. As she and her mom make their way to school, Mom explains how the butterflies are a thing. Everyone gets them (including parents) and they are a sign of something exciting happening—that we're about to learn and grow from a new experience and they can help us through it. So with the butterflies as her guide, the girl soars into her first day. Beloved children's songwriter Justin Roberts brings one of his most popular songs to the page, alongside beautifully tender illustrations by Paola Escobar, in a story guaranteed to help readers of all ages reframe their first-day nerves as first-day excitement.
