In this episode of The IBCLC Mentor Podcast, Margaret Salty dives into the latest research articles from her Google Scholar alerts, exploring how recent findings can enhance the practice of IBCLCs. Margaret breaks down complex research into actionable strategies for lactation consultants, focusing on how these insights can improve breastfeeding outcomes. Whether you're a seasoned IBCLC or just starting your journey, these episodes will keep you at the forefront of evidence-based lactation care.

Margaret discusses a study by Thomson & Garrido (2025) that explores how human milk influences the gut microbiota in preterm infants and its potential for optimizing microbial development. The study highlights the role of human milk in establishing a healthy gut microbiome and the long-term benefits for preterm infant health.

Thomson, P., & Garrido, D. (2025). How human milk shapes the gut microbiota in preterm infants: Potential for optimizing early-life microbial development. Microbiome Research Reports, 4(12), 1–11. https://doi.org/10.20517/mrr.2024.86

Practical Takeaways:

• Advocate for breast milk as the primary nutrition source for preterm infants.
• Educate NICU staff and parents about the impact of human milk on microbial development.
• Support donor milk programs to ensure preterm infants receive optimal nutrition.

This study by Hanumantharaju et al. (2025) analyzed how gestational age and lactation stage impact the microbiota of human milk. The findings suggest that preterm milk has lower bacterial diversity, emphasizing the need for targeted nutritional and probiotic support for preterm infants.

Practical Takeaways:

• Support early milk expression for mothers of preterm infants.
• Encourage sustained breastfeeding for optimal microbial diversity.
• Promote further research on regional variations in milk microbiota.

Margaret reviews a study by Faria et al. (2025) that examines how early breastfeeding initiation impacts obstetric outcomes, comparing data from before and during the COVID-19 pandemic. Findings reinforce the benefits of immediate skin-to-skin contact and early breastfeeding for both mothers and infants.

Reference:

Faria, A. P. V., et al. (2025). Obstetric outcomes in breastfeeding women in the first hour of delivery before and during the COVID-19 pandemic. BMC Pregnancy and Childbirth, 25, 24. https://doi.org/10.1186/s12884-024-06975-1

Practical Takeaways:

• Advocate for uninterrupted skin-to-skin contact immediately after birth.
• Support policies ensuring early breastfeeding initiation, even in pandemic conditions.
• Educate healthcare providers on the long-term benefits of early breastfeeding.

This birth cohort study by Feldens et al. (2025) investigates the relationship between tongue-tie (ankyloglossia) and maternal breastfeeding confidence. The study found no significant differences in breastfeeding self-efficacy between mothers of infants with and without tongue-tie, suggesting that non-invasive lactation support should be the first-line intervention.

Reference:

Feldens, C. A., et al. (2025). Ankyloglossia and breastfeeding self-efficacy in newborns: A birth cohort study. BMC Oral Health, 25(64). https://doi.org/10.1186/s12903-025-05444-1

Practical Takeaways:

• Assess breastfeeding challenges holistically rather than assuming tongue-tie is the primary cause.
• Prioritize latch optimization, positioning, and parental education before considering frenotomy.
• Work with multidisciplinary teams to provide well-rounded lactation support.

Staying updated with the latest research is essential for providing the best care as an IBCLC. By integrating evidence-based strategies, you can enhance breastfeeding support and outcomes. Tune in each week as we explore more insights from the world of lactation science.
