Times of transition can provoke informal learning that is both potentially transformative and often unacknowledged. New mothers living in a new country are in effect undergoing a double transition, and thus are in a position to possibly undertake a great deal of informal learning. This research focuses on migrant mothers living in Sweden and aims to understand their perceptions of their own learning at open preschools (öppna förskolor), or drop-in centers for young children and their caretakers. Through a small-scale qualitative study using semi-structured interviews, eight migrant mothers living in Solna municipality shared their memories and opinions about open preschools. The data was analyzed using thematic analysis and examined in light of Wenger’s (1998) social theory of learning and community of practice framework. The mothers overwhelmingly identified open preschools as places of support, with some also perceiving them as places of learning. Nonetheless, the findings show a great deal of informal learning related to mothering and mothering in a new country. There was a complicated relationship between supports and barriers to learning, reflecting the nuanced nature of communities of practice. In short, open preschools gave the participants a place to engage on their own terms with the intellectual work involved with forming their identities as migrant mothers. They also, however, encouraged the development of mothering identities that are in line with dominant Swedish discourses about gender and childrearing. This study proposes nevertheless that open preschools play a vital role in supporting parental learning and easing the transition to life in Sweden for migrant mothers.
