This anthology is a welcome contribution to the field of bi/multilingual child phonological development, offering new insights from various acquisition perspectives including bilingualism, bilectalism, trilingualism, heritage language, typical and atypical use. The cross-linguistic collection of studies spans a range of languages and diverse methodologies, advocating some novel solutions to long-standing debates.
