Every baby is a unique individual from the moment of birth, with their own likes and dislikes, strengths and sensitivities. One baby might find it hard to settle to sleep another may fall asleep easily, but might find being undressed distressing. Similarly, babies differ in what they find soothing and comforting. Only by being finely tuned to a baby's unique communications can an adult fully understand that baby and provide appropriate care. This book is based on evidence about the development of communication in infants collected in research institutes around the world. By using picture sequences from video footage, this book provides captivating illustrations of key aspects of infant experience. Together with an accessible text, these illustrations provide a window into the rich and complex social world of babies. The knowledge and understanding gained from this book will help all those concerned with the care of young infants to relate more sensitively and responsively to the babies who depend on them. It will also enrich their own experience and enhance their enjoyment.
