What's the happiest kid supposed to do when she wakes up not feeling happy? A reassuring picture book debut about recognizing sadness and talking about big feelings. Sally is usually the happiest kid. She wakes up every morning with a bright sun shining over her bed, and she knows it's going to be a good day. But one day she wakes up feeling different and there's a gloomy cloud hanging over her instead. She doesn't know why it's there, but she doesn't want anyone to see it--not her parents, not her teacher, and not her friends--so she hides it away. But as the day goes on, the cloud grows too big and heavy for her to carry, and Sally must find the courage to let it out. In this sweet story, Sarah Bagley Steele, Elsa Pu Si Lo, and Clarice Cai offer a gentle reminder that everyone feels sad sometimes, and that's okay.
