This book explores young children's language acquisition in multilingual households through an original longitudinal study of the author's own children and interviews with members of other Korean-English families. The study investigates how multilingual children not only acquire multiple languages (verbal communication) but also acquire multiple strategies of non-verbal communication. In the process, it is also revealed that parents learn from children, collaboratively shaping the language of their family together in a manner that is between and beyond languages and cultures. The book explores the different types and frequency of non-verbal behaviours acquired by multilingual children and reveals how multilingual families use a range of multimodal resources to communicate effectively in a way that creates solidarity. The results of this longitudinal study are discussed within the paradigm of translanguaging and provide insight into an underrepresented multilingual population. With
