Book excerpt: This transformative book looks at one of the most undervalued aspects of childhood, joy. Using the latest neuroscience and biochemistry this book shows that joy, far from being an abstract concept, is one of the key motivators for every aspect of learning and development throughout childhood and something we ignore at our peril. The book gives concrete strategies for increasing the levels of joy in our children and highlights the catastrophic damage that a decline in joy can cause in our children especially in a post pandemic world. Suitable for anyone who works with children, this book puts forward a compelling argument that Joy is profoundly important for all of our children and can fundamentally help our children to thrive.
