Description A living, breathing, real-world handbook—tested over 10 years on the front lines of parenting. The system no one ever taught you about raising kids. "Why isn't there a Nobel Prize for parenting?" I asked myself this question countless times after becoming a mother. The answer is simple: parenting is incredibly difficult and complex, yet no one ever recognizes it as real work. Even hiring someone for just one hour costs money and requires careful vetting. This isn't something you can just wing with instinct alone—it's clearly a highly skilled, professional job. A paid job. And yet, there has never been a proper, structured, practical manual for it. So I created one. The real system behind parenting that no one ever explained—a living handbook, ready to hand off. Sleep training, weaning, discipline, scheduling, attachment, and even mental health—this book brings together the standards proven over 10 years with a million parents. This is one of the most important jobs in all of humanity, yet no one has ever treated it as actual work. This isn't just another collection of tips. It's not a transcript of a lecture, nor a trendy grab-bag of hacks. Built on structured thinking learned at MIT, this book maps out every parenting situation and has been tested and proven in the real world—a true practical handbook, ready to pass on. You no longer have to struggle through it alone. This is the book that finally gives the project of parenting a clear direction and a solid standard: Ttokge Yuga All-in-One. [Recommendations] "Turning parenting from guesswork into a system. Ttokge Yuga was the practical strategy guide that reset my parenting and gave me real confidence." — Kim Sun-a (Ttokge Yuga 6–12 Month Membership Member) "Parenting felt overwhelming and exhausting. But a big part of that struggle came from not having any clear standards to follow. There were days when love alone wasn't enough to get through. In the middle of that confusion, I'd cry and ask myself, 'Am I even doing this right?' Every time that question came up, this book always explained why and showed me what to do. I felt like I was reading a record of 10 years of the author never giving up—trying things firsthand, hitting obstacles, coaching parents one-on-one, and finding real answers." — Choi Yeon-su (Ttokge Yuga 0–3 Month Membership Member) "When parenting felt impossible, I wished someone who had already been through it could be right there beside me. This book feels like that hand. The author's relentless 10 years of research and effort, the sincerity and direction behind real solutions found in the trenches—these are what get me through each day now." — Moon Jung-yeon (Ttokge Yuga Consulting Member) "10 years. A million parents. This is now K-parenting—a record of someone who made it through, and a living strategy guide." — Kim Min-ji (Ttokge Yuga 3–6 Month Member) "Parenting is a series of choices every single day. Anyone can search for information. But making the judgment call—that's on the mom. That's why direction matters. This book shows you that direction." — Seol Hyun-jung (10-Year Fan of Ttokge Yuga, Early Reader) "This isn't just a parenting book. It's a life reset manual—for organizing who you've become as a mother, understanding your child, and designing your family's future together." — Lee Eun-chae (10-Year Fan of Ttokge Yuga, Early Reader)
