SummaryNorway s population was in April 2016 estimated to be 5 223 300 persons (SSB, 2016b). The Norwegian Directorate of Integration and Diversity (IMDI), estimated that in 2015, 13% of the entire Norwegian population were people with a migration background (IMDI, 2016); many of these being preschool aged children. With 90.4% of all children between the ages of 1 and 5 participating in day care (SSB, 2016a); many migrant children are represented among the day care population. Even though the body of research in relation to diasporic, migrant and mobile childhoods is growing, there are reasons to be critical as much of it fails to capture the situated and contextualised nature of newcomer migrant children s negotiations of identity, home and belonging .In Norway, early childhood day care is promoted as one of the best integrational arenas in which migrant children (including those seeking asylum and refugees) can receive early intervention aimed at easing their transition into future school and society. However, with an intervention focus on future integration, entering an ethnic and culturally diverse early childhood environment, such as day care, can be cha llenging for many reasons.

The research approach is anchored within the interpretivist/constructionist research paradigm and in line with the underlying principles of the sociology of childhood. The theoretical background draws on but is not limited to sociology, cultu ral studies and social With particular interest on how, in everyday life, newcomer children s personal problems are interlaced with structural issues , the thesis highlights the complexity of in particular ii these two girls everyday social struggles, adapting to a highly dynamic and evolving environment. This thesis reveals the girls as being active participants in their multilayered and complex transition s characterised by continuous negotiations of identity, home and belonging.The overarching aim of this thesis is to contribute to the early childhood migration discourse, using its findings as a means to strengthen the care environment for newcomer migrant children and building respect for childhood diversity. Through detailed qualitative analysis of small sample sizes of selected empirical data, the data are used to illustrate aspects of the two newcomer girls everyday worlds. The four articles written for and presented within the thesis address the intersection between what facilitated the girls integration and inclusion in everyday social reality by highlighting how equal opportunities for integration and inclusion depended on not only the girls ability to negotiate identity, home and belonging with both peers and practiti...
