"[Lange] might be the most influential design critic writing now." -The Los Angeles Review of Books

From building blocks to city blocks, an eye-opening exploration of the ways children's playthings and surroundings affect their development-now featuring the author's Pulitzer Prize-winning essays.

Parents obsess over their children's playdates, kindergarten curriculum, and every bump and bruise, but their toys, classrooms, and playgrounds are just as important. These objects and spaces encode decades-even centuries-of ideas about good child-rearing versus bad. What is the Good Toy? Is it wooden, plastic, or even digital? What do youngsters lose when seesaws are deemed too dangerous and slides are designed primarily for safety? How can our built environment help children cultivate self-reliance? In these debates, parents, educators, and kids themselves are often caught in the middle.

Now, Pulitzer Prize-winning design critic Alexandra Lange reveals the surprising histories behind the human-made elements of our children's pint-size landscape. Her fascinating investigation shows how the seemingly innocuous universe of stuff affects kids' behavior, values, and health. Along the way, she reveals how years of decisions by toymakers, architects, and urban planners have helped-and hindered-American kids' journeys toward independence. Seen through Lange's eyes, everything from the sandbox to the street becomes vibrant with meaning. The Design of Childhood will change the way you view your children's world-and your own.
