2 is a little. 0 is nothing. 1 is not enough. Well, sometimes... 1 sun is a lot. 1 dog is a lot. 2 can even be too much. And when it comes to rain clouds, 0 is perfect. It's curious, but true. It all depends on what you're counting! Bestselling and critically acclaimed author Muon Thi Van offers an innovative and thought-provoking look at the question, How many is enough? Simple page by simple page, young readers are shown examples of how, when counting things, the smallest numbers - 0, 1 and 2 - can mean a little, a lot or just the right amount.
