You've probably heard the saying that we must be kind because everyone is fighting a harder battle than we realize. While traditionally the quote is attributed to Plato, we think nothing has taught the virtue of kindness more powerfully than good children's books. That's why we created this extensive list of the top children's books about kindness. Kindness is contagious and beautiful. It can make the most gloomy day sunny, dry tears and change the world. It's a powerful force that we learn how to use, though it's also innate. Kindness might be hard to describe to a young reader, but it's very easy to show. This list features story books that offer concrete examples you can share and discuss with your kids about what it means to be kind, like the importance of helping others and using kind words. Some titles also cover specific aspects of kindness, like being kind to animals. In these books, you're sure to discover favorite new characters and book quotes that will help your child understand what it means to be kind. Our list can also help you find the best books for discussing certain aspects of kindness, like how kindness incorporates showing compassion, or how developing empathy helps us be more kind, or how kindness and friendship build on one another.
