This poetic picture book introduces readers to a collection of baby animals doing what comes naturally--nursing. The luminous illustrations and lyrical text give children a glimpse into the worlds of 13 different mammal babies. Compelling childhood facts broaden the reader's knowledge about each species.

The overarching theme of breastfeeding inspires conversations about parenting, biology, habitats, survival, and more, making this book an engaging choice for young children as well as elementary school readers. An extensive Teacher's Guide, available for free download in English and Spanish, enhances the book's content, increasing learning opportunities.
