Hi, readers. This book was written by my professor at 筑波大学(心理学系). He has written many books and articles, but this book seems to be quite popular among parents. Professor Sugihara died last year. He was a tremendous influence in my life, not only for believing in me, and giving me a chance to become a child psychologist in Japan, but also becauase of his amazing personality. I have missed him very much.
