Single motherhood is a growing phenomenon in South Africa, as it is in the world at large. The concept and structure of a family have changed over the last few decades and no single definition will suffice to describe or define it anymore. Various factors impact on the psychological wellbeing of the single mother. The psychological wellbeing or mental health of the single mother can influence her parenting abilities. The aim of this study is to explore the lived experience of a single mother with three dependent children, to gain a deeper understanding of her experiences as a single mother and the meaning she attaches to it. The point of view of this research is from a constructivist-interpretivist paradigm and from an ecological systems theory approach. This qualitative research study uses a single case study method with unstructured interviews to explore the participant’s experiences. Interpretative phenomenological analysis is used to analyse data, to identify main and sub-themes from the collected data, and to compare these themes with identified themes on single motherhood from existing research. The participant’s lived experience reveals that financial hardship is not the main contributing factor to stress experienced by this single mother. The accumulative effect of diverse stressors and the lack of social support due to prejudice and stigma seem to have a greater effect. This study generates questions around the stigma of single motherhood in South Africa. The reading of this text could raise the reader’s awareness of the challenges faced by single mothers and of prejudice against them. Single mothers are not less capable as individuals of handling the challenges of motherhood and parenting, but they are often exposed to more demands and stressors, compared to partnered mothers. Changing our perspectives on single motherhood can reduce prejudice, offer more social support and improve access to other needed resources.
