All over the world, there are people speaking a minority language in a bi/multilingual environment and many of those people choose to shift to languages of wider communication. Family’s role is on focus, in order to preserve and maintain minority language alive. Family has a very significant role in child’s language socialization. In combination with the family language policy approach (FLP), the interest can be shifted to what can be done in order to maintain a minority language alive. This study, influenced by the language socialization and FLP approach, is focusing on Greek speaking parents raising their children bilingually in Sweden. More specific, the research aims to bring out the language practices that thirteen parents narrate they apply and the challenges they encounter in the process of language maintenance and shift. Four group interviews were conducted and the data, which were analyzed with the help of the thematic analysis, prove that language management and planning differ from family to family and cannot be static, while many factors, such as children’s agency, influence the language maintenance process.
