Boys are way more troublesome than girls. A well-behaved, self-disciplined girl and an idle, aimless boy are poles apart. As such, there is no one-size-fits-all approach for raising kids. Parents should strike a balance between “let go” and “plan for kids,” shifting between free-range and elaborate parenting. Gai Zhaoquan, a famous expert in English for kids, writes this book focusing on the upbringing of boys, based on her years of research, observation, and analysis. Gai used to interview hundreds of parents for her study in English for kids and have witnessed the growth of many children. Taking her own son as an example, Gai introduces in a detailed way her decade of experience in raising kids from the perspectives of physical health, parent-child relationship, character-building, communication skills, and academic record. Suggestions included in the book, being reader-oriented, are all universal, sensible, and practical, taking into account the fact that children are born different.
