Life’s an awesome adventure, filled with highs and lows—sometimes all in the same day. This delightful book explores the idea of life’s shifting sands. Through simple, bouncy verses and charming, colorful illustrations depicting a variety of scenarios, readers learn that some days will be filled with triumphs, friendship, and excitement, while others might deliver disappointment, hurt, sadness, fear, loneliness, and self-doubt. In other words, life isn’t static. The author and the illustrator present relatable ideas and visuals that will help children easily grasp the message. Happy days are described as yellow; sad ones are blue. The cheerful rhymes and bright, lively images—a mix of full-page art and vignettes—work together well, using the concept of opposites to help kids compare the inevitable ups and downs of daily life: “Some days are fast! Others seem slow.” “Some days are ‘Yes.’ Others all ‘No!’” Children will feel reassured by the book’s auspicious premise that no matter what’s occurred today, a brand-new tomorrow is inevitably on the horizon. Characters are racially diverse; one light-skinned child is depicted using a wheelchair. After reading, kids may want to volunteer their own ways to describe yellow and blue days.
