Promoting breastfeeding is important work for health-care personnel in the Swedish context. This promotion is multifaceted and demands the ongoing development of knowledge and competence among both health-care  personnel and patients.  The aim of the present study was to describe the nursing students’ perspectives on breastfeeding in Sweden. Data were obtained in the form of written reflections from nursing students (n=65) and examined using manifest content analysis. The results show that the factors of importance in promoting successful breastfeeding are information about breastfeeding’s benefits, traditions and cultural acceptance of the practice, and by government prohibition of infant formula. We conclude that knowledge about the benefits of breastfeeding needs to be prioritized continuously during education.
