The first lockdown of the COVID-19 pandemic resulted in school closures and homeschooling for families across the world. This provided a unique scenario to investigate multilingual family language interaction, and specifically, challenges and opportunities for home language (HL) use. This study is rooted in Family Language Policy (FLP) research, building on previous models of language policy as language beliefs, practices and management, as it addresses the effects of the lockdown on the use of, and exposure to, HLs. An online survey was used to assess the language beliefs, practices and management in a sample of families in Norway, a country with a significant and complex linguistic diversity. Our results indicate overall positive attitudes towards multilingualism in Norway, which are associated with an increased use of, and exposure to, Norwegian and HLs during the lockdown. Furthermore, we find a unique presence of English in multilingual families in Norway, especially across online spaces. Lastly, our study shows that the perception of multilingualism as a source of well-being is associated with positive effects of the lockdown in the use of HLs during the pandemic. We contend that this result can be taken as an example that, even in dire times of despair, families can find opportunities to promote multilingualism and language maintenance.
