Babies and engineers have more in common than you think.In this book, Alexander highlights the unlikely similarities between babies and engineers. Like engineers, babies ask questions, enjoy building, and learn from their mistakes. Black's bold, colorful illustrations feature diverse babies and both male- and female-presenting adult characters with a variety of skin tones and hair colors, effectively demonstrating that engineers can be any race or either gender. (Nonbinary models are a little harder to see.) The story ends with a reassurance to the babies in the book that "We believe in you!" presumably implying that any child can be an engineer. The end pages include facts about different kinds of engineers and the basic process used by all engineers in their work. Although the book opens with a rhythmic rhyming couplet, the remaining text lacks the same structure and pattern, making it less entertaining to read. Furthermore, while some of the comparisons between babies and engineers are both clever and apt, others—such as the idea that babies know where to look for answers—are flimsier. The book ends with a text-heavy spread of facts about engineering that, bereft of illustrations, may not hold children's attention as well as the previous pages. Despite these flaws, on its best pages, the book is visually stimulating, witty, and thoughtful.A book about engineering notable mostly for its illustrations of diverse characters. (Board book. 1-3)
