When Mr. Neill was correcting the proofs of The Problem Child, he realized suddenly that he had written the wrong book. "There isn't a problem child," he said, "there is only a problem parent." That was some years ago, and then he had no time to tell the problem parent what he thought of him . . . and her. Now the book of the parent has been written. Mr. Neill has been called the only genius in modern education. The Problem Parent is a wise book, full of new ideas of value because they are the results of long experience in child and adult psychology. It is a book that will shock the die-hards into thinking and the go-aheads into action.
