In a feel-good concept book, the Geisel Award-winning illustrator of See the Cat gives young children a vocabulary for naming--and managing--their emotions. From delight to disgust, excitement to fear, worry to confidence, boredom to curiosity, feelings can shift in a heartbeat. Mike Wohnoutka's simple words and tender, nuanced illustrations follow three young children as they traverse emotional highs and lows over the course of a school day. The wide spectrum of emotions covered--far beyond happy and sad--invites readers to share their own contradictory, unpredictable, ever-present feelings. Vetted by an expert in the science of children's emotions, this day in the inner life of three kids encourages first steps toward emotional literacy and is a satisfying narrative that ends with the adorable trio converging after school in the park--ready for play!
