OBJECTIVES: In high-income countries, the number of women who choose to become single mothers is rising. This trend is also reflected in Denmark. The aim of this study was to explore the decision- making process of becoming a solo mother.

STUDY DESIGN: This study was designed as an explorative, qualitative study. Semi-structured interviews were conducted face to face or by telephone, to explore women's thoughts and experiences of becoming solo mothers. A systematic text condensation and interpretation were used to analyze the interview material.

RESULTS: Twenty solo mothers-to-be participated in the study and 38 interviews were conducted, before and after pregnancy. Four themes related to the journey of solo motherhood emerged from the data analysis: The dream of motherhood in a nuclear family - a shattered dream, Achieving socio-emotional acceptance, approaching motherhood with a comprehensive plan, and the fatherless child.

CONCLUSION: The nuclear family was considered as the ideal family among our participants. The decision to become solo mother was characterized by a long process of reorganizing ideas about a family. In the effort to feel more secure about being a solo parent, to control the process and reduce vulnerability, most women drew up a detailed motherhood plan, even before embarking on the project.
