This is an accessible, practical guide to preventing and managing children's allergies and improving their immune systems. Childhood allergies are booming, affecting almost one in five Australian kids. But what if there was a way to prevent allergies in the first place? What if simple lifestyle changes in the critical first 1000 days could change your baby's life? For families across Australia, eczema, asthma, hay fever and food allergies are constant anxieties, sometimes with devastating consequences. Leading gastroenterologist Dr Vincent Ho has taken a deep dive into the exploding medical field of gut health and explains that from conception to birth, and from breastfeeding to the introduction of solid foods, small steps go a long way in preventing allergies and fortifying your baby's immune system. Dr Ho cuts through the scientific jargon to provide strategies for allergy management and treatment, and shows you how to strengthen your child's gut health for the long term - all before they begin to walk. This book is packed with sensible advice, surprising scientific discoveries and even a nutritionist-approved nine-week infant meal plan to help parents navigate the introduction of common allergenic foods. Practical, easy-to-follow and utterly eye-opening, this book is essential reading for every parent and parent-to-be.
