The Lorax by Dr. Seuss
Of course The Lorax is great, it is by Dr. Seuss. It is a wonderful story that reminds us that the world we live in is beautiful, that every living thing is connected, and that we need to conserve our natural resources. But what's more is that it rhymes and offers us awesome words and phrases like "where the Grickle-grass grows," "his Snuvv, his secret strange hole in his gruvvulous glove," the "Whisper-ma-Phone," and "Brown Bar-ba-loots" in their "Bar-ba-loot suits." Reading this book to Baby is a verbal joy.
