"Unlike many picture books that seek to comfort young audiences by assuring them that their apprehensions are unfounded, Donnini’s quiet prose shows readers that worry is a feeling as valid as any other . . . the world is an increasingly worrisome place, and books like this one, that offer simple acknowledgement of this fact, are just as essential as those that offer elaborate escape. Timely assurance of the impermanence of life’s difficulties." —Kirkus Reviews
