Aims and objectivesTo describe women's experience of not breastfeeding in a breastfeeding culture.BackgroundBreastfeeding represents a fundamental cultural value in Norway and many other countries, and a mother may often have intense emotions about breastfeeding her child. Political and health authorities in many countries have given high priority to encourage breastfeeding among mothers. However, breastfeeding can be challenging and sometimes affects mothers’ mental health and the joy of interaction.DesignQualitative design.MethodsIndividual semistructured interviews with 12 mothers. Qualitative content analysis was used to analyse the interviews.ResultsThree main categories emerged from the data: (1) desire to adapt to Norwegian culture, (2) feeling as though one was breaking the law and (3) lack of and unbalanced information. The mothers in this study wanted to breastfeed, both to do the best for their child and to fulfil cultural expectations. They knew about the advantages of breastfeeding. When breastfeeding was stopped, they needed social support because they felt it was difficult to do the opposite of what was most common in the culture.ConclusionHealthcare workers should consider the mother's individual situation when providing breastfeeding guidance. Information about the advantages should be adequately balanced and nuanced to prevent shame and guilt. Healthcare workers should have sufficient knowledge about how to ensure that infant formula is used correctly.Relevance to clinical practiceHealthcare workers should pay attention to the mother if she has limited social support, and they should organise peer support. Healthcare workers must ensure that mothers get balanced information about the benefits of breastfeeding and about the differences between breastmilk and infant formula. To ensure that infant formula is used correctly and to reduce stigma, healthcare workers should have sufficient knowledge about formula feeding and health authorities could provide information about how to prepare infant formula.
