For anxious new parents who constantly wonder if they're raising their child right, here are 70 essential insights covering sleep, temperament, crying, play, and psychological development for children ages 0-2. "I don't know why my baby cries so much." "My baby fusses terribly at bedtime." "My child is so difficult and sensitive it's driving me crazy." "I feel depressed just looking at my baby." "My child is so afraid of strangers." "When angry, my child throws things and bangs their head on the floor." "My child's speech seems delayed compared to peers." "Why is my child so restless?" "When should we start potty training?" "Could my child possibly have autism spectrum disorder?"... Dr. Shin Eui-jin, one of Korea's foremost experts in child development, has organized 70 essential parenting insights that parents of children ages 0-2 need to know, centered on key themes like crying, sleep habits, temperament and personality, and play and learning. For first-time parents, everything about raising a child feels unfamiliar and overwhelming. Countless websites offer parenting information, but there's no way to know if that information is accurate or truly right for your child. For new parents who feel lost as they step into the world of parenting, Dr. Shin has drawn on 25 years of clinical experience counseling over 600,000 patients, well-established developmental theories, and her own hard-won experience raising two challenging sons, to compile accurate information and practical solutions to parents' most pressing questions. This newly expanded edition, published to mark the milestone of 300,000 copies sold, includes a special section on "10 Warning Signs Parents of Children Ages 0-2 Should Never Miss," allowing parents to self-check their child's developmental progress. For parents who want to raise their children well but struggle without knowing how, this book offers guidance to turn to whenever they hit a wall. "Why do they cry? Why won't they sleep? Why won't they eat? Why is their speech delayed?" A clear, accessible guide to the psychological development that's easy to overlook when focusing only on visible growth. Dr. Shin explains that there's really just one reason parenting feels so hard: parents don't understand their child's developmental process and psychological state. Especially from birth to age two, it's a critical period when parents need to respond positively to their child's behavior, smile, hug, soothe, and try not to crush their child's will even when they're being quite stubborn. Only then can a child develop a positive self-image and secure attachment with their parents, allowing them to step out into the world with confidence. If parents remain unaware of these developmental characteristics and instead focus solely on mechanical milestones and habit training like "by such-and-such month, they should be doing this," the child may lose something far more important for their future: self-esteem and a positive, happy outlook on the world. This book brings together everything about a child's psychological development that's easy to miss when focusing only on visible growth. When your child cries inconsolably, insists everything is "mine," acts out excessively, or can't seem to break a bad habit like thumb-sucking—for these everyday parenting challenges, this book carefully walks through exactly how parents should wait patiently, and when and how to step in, offering practical solutions every step of the way. This book holds the key to raising your child well without hurting their feelings. "Tomorrow's parenting doesn't have to be scary anymore!" Dr. Shin Eui-jin's realistic, clear-eyed parenting guidance to help you break free from the daily stress of raising a child. Even when parents are well-informed about child development, day-to-day parenting is never truly easy. Parenting challenges are never solved with a single effort—they require consistent, ongoing work. And when postpartum depression or the guilt of working parenthood is added to the mix, the joys and rewards of parenting can feel like they belong to someone else's family. Dr. Shin herself, as a mother who raised two challenging sons, knows firsthand how difficult and exhausting parenting can be. Perhaps that's why she offers this 'warning': don't try too hard to be a perfect parent. If you're feeling overwhelmed, she advises taking time to rest outside before coming home, actively seeking help from those around you, and recognizing that even if you spent everything you earn in your child's first three years on their care...
