The purpose with this study is to find out the experience of growing up in a family where the biological parents, has taken the assignment as family child caregiver’s. We have taken the help from the following question formulations to immerse ourselves in the subject. How do the biological children experience their relationship to their parents? How do the biological children experience their relationship to the children who are placed in their home? How do the biological children experience their participation in the family home? How do the biological children experience the need for support from outside the family? We have used a qualitative research method and interviewed six respondents with help from a semi-structured interview guide to get the respondents unique experiences told. In this way the respondents own perspective is presented in a phenomenological way, without coloring their stories with our own naive theories. We have processed the material with help from topics that affect our question formulation. Sibling relationship, relations to parents, participation and support from social welfare and also the family home assignment. The results from the interviews are introduced with help from the Attachment theory, KASAM, Systems theory, literature and research in the subject. Our conclusions are that the biological children have had a participation in the decisions concerning the family home. We have also established that the biological children in our study rarely had to take responsibility for the children placed in their home. The result also shows that the biological children experience varying relationships to the children placed in their home. Some respondents describe it as a sibling relationship while some describes their relationship to the placed children more like a friendly relationship. Our respondents experiences to their parents are good with some exceptions during some particular troublesome periods in their growth. Everyone told us that they could talk to their parents about most of the things regarding the family home but they also said that they felt the need of a person outside the family to talk to, like some support from the social services.
