The Milk Makers by Gail Gibbons

You probably drink milk at almost every meal. But have you ever wondered where it comes from?
Cows eat special feed to make good milk. But after the cow is milked, there are still many steps the milk must go through before it reaches you. This book describes them all. And you'll be surprised to find how many other things you eat and drink come from milk, too.
Gail Gibbon's unique style makes this a fascinating book for children and adults alike.
