Big Bird and Little Bird explain their preferences for all things big and little. For example, Big Bird likes mountains, while Little Bird likes molehills. My daughter loves reading this book. Partly because my husband has a really funny squeaky voice for Little Bird, but mostly because it's just a fun book. I think this book is good for teaching young children about opposites and I like how it ends with the two birds admitting that there is one big/little thing that they both love....each other. ( )
