Breastfeeding is a significant public health issue, offering well-established benefits for both mother and child. The experience of breastfeeding is shaped not only by biological and social factors, but also by the quality of medical and emotional support received after childbirth. The general practitioner (GP) plays a pivotal role in continuity of care, yet their involvement in providing breastfeeding support is not well understood.To explore the meaning of the GP–parent relationship in supporting breastfeeding through an approach that focuses on lived experiences.A qualitative interpretative phenomenological analysis (IPA) was conducted with six mothers living in XXX who had exclusively breastfed their full-term children under the care of a GP. Participants were recruited via posters in medical practices, social networks, and personal contacts. Data were collected through non-directive interviews, which were recorded and fully transcribed. Analysis was performed according to IPA stages in symmetrical triangulation between two researchers until data saturation was achieved.Breastfeeding was found to be a complex experience, incorporating physical, emotional and social elements. The GP–mother relationship fluctuated between recognition and misunderstanding, depending on the physician’s capacity to listen, validate emotions, and customise guidance. Mothers valued relational qualities such as empathy, trust, and recognition of their expertise as mothers, perceiving these qualities as therapeutic in themselves. Conversely, a lack of acknowledgement or a prescriptive stance from the GP often reinforced maternal guilt and isolation.This study provides an original exploration of the breastfeeding experiences of mothers in relation to their GP. Its methodological strengths include in-depth, rich interviews; a reflexive stance; and rigorous triangulation. The study highlights relational factors that shape breastfeeding and supports the public health relevance of the topic. However, limitations relating to sampling, contextual specificity, timing, researcher influence and the lack of clinical observation mean that there are several avenues for future research.This study highlights the importance of the relationship between GPs and mothers in determining whether they continue to breastfeed. The GP’s role extends beyond providing medical advice to encompass offering emotional and symbolic support. Training programmes should therefore integrate experiential and phenomenological approaches to strengthen the relational foundations of primary care.
