Have you ever been told that raising your child to speak multiple languages will harm their development? Are teachers or other professionals suspicious of your efforts? Are you sometimes unsure if you are helping your childa (TM)s language development, or are you uncertain where to start? It is increasingly recognised among researchers that, far from harming a childa (TM)s development, being exposed to multiple languages from birth or early childhood can result in linguistic, creative and social advantages. The authors, all multilinguals themselves, parents of multilingual children, and researchers on language and multilingualism, aim to provide advice and inspiration for multilingual families across the world. The latest research on multilingualism and the authorsa (TM) own experiences are used to provide a friendly, accessible guide to raising and nurturing happy multilingual children.
