Objective To explore the aversion experiences of breastfeeding among postpartum women and their coping strategies, and to provide a reference for developing relevant nursing interventions. Methods A total of 20 parturients who attended the breastfee-ding consultation clinic from January to October 2024 were selected as research subjects using the purposive sampling method.Semi-structured interviews were conducted with the parturients adopting a descriptive qualitative research method, and the data were analyzed, summarized and refined by content analysis. Results Three themes and nine sub-themes were extracted, namely:aversive emotional experiences of breastfeeding (real-time nature, uncontrollability and specificity of breastfeeding aversion; conflict between breastfeeding aversion and willingness to continue lactation; self-denial);impacts of breastfeeding aversion on family relationships (disrupting mother-infant emotional bonding; eroding trust and expectations in marital relationships; creating communication barriers among family members);coping strategies for breastfeeding aversion (self-regulation; family support; social support). Conclusion Medical staff should dynamically assess the mental health status of parturients during breastfeeding, pay close attention to the aversive emotions they experience during lactation, and timely optimize family and social support systems for them, so as to promote healthy breastfeeding practices.
