This volume is a welcome contribution to the growing literature on family language policies and heritage language maintenance. Through the lens of the Polish diaspora in Australia, it presents a comprehensive and captivating account of the dynamics of family language policies, illustrating how they are constantly negotiated, contested and formed by both parents and children.Elizabeth Lanza, University of Oslo, NorwayThis is the first comprehensive study of the Polish community, one of the well-established yet understudied groups that make up multicultural Australia. The book explores the community’s attitudes, beliefs and practices to maintain the heritage language against the backdrop of limited institutional support. Piotr Romanowski has produced a rigorous yet highly engaging contribution to the flourishing field of Family Language Policy, as well as a model to study other ethnolinguistic communities. Susana Eisenchlas, Griffith University, AustraliaThis research is a valuable interdisciplinary examination of heritage language transmission ecology within a group of Polish immigrant families in Australia. Piotr Romanowski traces current tendencies in transnational families’ Family Language Policy, such as minority-language parents' legitimising of flexible happylingual practices as well as minority language support by majority-language parents. Importantly, the book demonstrates an essential shift in emphasis from traditional Family Language Policy research "on" or "about" children to research "with" children. This significant work of scholarship will become essential reading not only for researchers in multilingualism but also for scholars of family and ethnic studies, as well as child development. Mila Schwartz, Oranim Academic College of Education, IsraelThis book makes a solid and important contribution to not only the burgeoning literature about Family Language Policy but also our general understanding of linguistic, sociocultural and educational practices in an increasingly multilingual world.
