Abstract

Breast pumping is a central part of infant feeding for many parents, yet professional guidance often gives limited attention to psychosocial and experiential aspects. Online communities offer valuable insight into how parents describe and navigate these experiences. Large language models provide new opportunities to analyze large volumes of online discussions.To identify and describe major thematic patterns in online discussions about breast pumping and infant feeding, with a focus on sensory concerns related to stored milk and their links to parental distress.Four subreddits related to pumping and breastfeeding were selected, and 107,447 relevant posts, extracted from November 2010 to December 2024, were retained in the analysis. Relevant content was identified using a combination of keyword matching and semantic similarity. Eleven binary-coded questions covering practical, experiential, and psychosocial topics were developed. Llama 3.1 8B was used for systematic classification. Ten questions achieving classification accuracy above 75% were retained. Multiple correspondence analysis was used to explore underlying thematic dimensions. A Supplementary keyword co-occurrence analysis examined discussions of sensory changes in stored milk.Four main dimensions were identified, explaining 52.5% of total variance. Dimensions 1 (16.2%) and 2 (13.6%) differentiated discussions focused on feeding decisions and emotional experiences from those explicitly addressing sensory changes in expressed milk. Dimensions 3 (11.8%) and 4 (10.9%) distinguished concerns about perceived effects of pumping on milk quality from practical and work-related aspects of pumping. In r/ExclusivelyPumping, frozen milk storage was discussed in 7.8% of posts, while 2.7% mentioned sensory concerns (taste, smell, soapy, metallic, sour). Among posts referencing lipase, 43.0% also discussed frozen milk stash, and 21.1% mentioned scalding as a preventive strategy.These findings suggest gaps in current guidance on milk storage and quality and highlight the need for more targeted support and interventions for pumping parents. Although sensory changes in stored breastmilk were mentioned relatively infrequently, they emerged as a distinct theme in pumping-related discussions. The frequent co-occurrence of lipase concerns with frozen milk stashes reflects a recurring situation in which parents discover sensory changes only after substantial effort has been invested in building a stored milk supply.Copyright © 2026 Kaloudis, Silpe, Mourelatou, Damian-Medina and Bountziouka.

对于许多父母来说，母乳喂养是婴儿喂养的重要组成部分，然而，专业指导往往对心理社会和体验方面关注不足。在线社区为我们深入了解父母如何描述和应对这些经历提供了宝贵的视角。大型语言模型为分析海量在线讨论提供了新的契机。本研究旨在识别和描述关于母乳喂养和婴儿喂养的在线讨论中的主要主题模式，重点关注与储存母乳相关的感官问题及其与父母焦虑的联系。我们选取了四个与母乳喂养和母乳喂养相关的Reddit子版块，并保留了2010年11月至2024年12月期间的107,447条相关帖子进行分析。我们结合关键词匹配和语义相似性来识别相关内容。我们设计了11个涵盖实践、体验和心理社会主题的二元编码问题。我们使用Llama 3.1 8B进行系统分类。最终保留了分类准确率超过75%的10个问题。我们使用多重对应分析来探索潜在的主题维度。一项补充关键词共现分析考察了关于储存母乳感官变化的讨论。分析确定了四个主要维度，解释了总方差的52.5%。维度1（16.2%）和维度2（13.6%）区分了侧重于喂养决策和情感体验的讨论与明确讨论挤出母乳感官变化的讨论。维度3（11.8%）和维度4（10.9%）区分了对吸奶对母乳质量影响的担忧与吸奶的实际操作和工作相关方面。在r/ExclusivelyPumping版块中，7.8%的帖子讨论了冷冻母乳储存，2.7%的帖子提到了感官问题（味道、气味、肥皂味、金属味、酸味）。在提及脂肪酶的帖子中，43.0%也讨论了冷冻母乳储存，21.1%的帖子提到了用热水烫伤作为一种预防策略。这些发现表明，目前关于母乳储存和质量的指导存在不足，并强调了为吸奶父母提供更有针对性的支持和干预措施的必要性。尽管关于储存母乳的感官变化的提及相对较少，但它在与吸奶相关的讨论中却成为一个显著的主题。冷冻母乳储存中脂肪酶问题的频繁出现，反映了一种反复出现的情况：父母往往在投入大量精力建立储存母乳后，才发现母乳的感官变化。版权所有 © 2026 Kaloudis、Silpe、Mourelatou、Damian-Medina 和 Bountziouka。
