A new ultrasound study by Dr Zoya Gridneva sheds light on how shape during established lactation

In this ultrasound investigation of 34 lactating women (1–6 months postpartum), we explored how maternal adiposity, breast anatomy, and milk production interrelate.

Key takeaways:
• Glandular tissue representation (GTR) varies widely among individuals and is linked to milk production.
• Milk duct number and diameter, along with mammary blood flow, appear to influence 24-hour milk production.
• Higher adiposity correlates with reduced breast growth during pregnancy, lower GTR, and lower milk production.
• Later menarche and reduced pubertal/pregnancy breast growth associate with reduced ductal structure and lower milk output.
• Findings suggest antenatal lactation assessment and targeted interventions in high-risk women could help maximize lactation potential.

Why it matters:
• Improves understanding of the anatomical and physiological underpinnings of lactation.
• Highlights potential modifiable factors (e.g., adiposity) and informs approaches to support breastfeeding success.
• Opens avenues for personalised lactation care and earlier interventions for those at risk of low milk supply.

This study is published in J Imaging (2025) and is part of ongoing work from UWA’s Centre for Human Lactation Research and Translation.

A new study from Dr Lisa Stinson on the cohort shows that the human milk is dynamic and shaped by real-world factors. Using full-length 16S rRNA sequencing on 266 milk samples from 208 mothers (3 weeks and 3 months postpartum), researchers found:
• Substantial inter-individual and temporal variation in milk microbiota
• Milk bacterial composition and diversity linked to maternal, socioeconomic, and breastfeeding factors
• Intrapartum antibiotic prophylaxis and exclusive breastfeeding markedly influence the milk microbiome, even months after delivery

Key takeaways:
• The milk microbiome is not static; clinical and lifestyle factors can modulate which bacteria are transmitted to infants.
• Understanding these drivers could inform to maternal and infant health during the critical early months of life.

If you’re curious about how delivery-related antibiotics and breastfeeding practices shape early-life microbial exposure, this is a landmark multi-ethnic Asian cohort study worth a read. https://buff.ly/awvuWtB

A new study explores low milk production after birth

Drs Nicole Manshanden and Joost Velzel from Noordwest Ziekenhuisgroep in The Netherlands collaborated with our Centre at The University of Western Australia to complete this study. Nicole on your first ‘first author’ paper!

Researchers looked at 136 breastfeeding mums to compare those with lower milk production in 24 hours (less than 600mL) to those with normal production.

Key takeaways:

- About 1 in 4 mums reported they had experiences a lower milk production.
- Some mums with low milk production had impaired breast development, or ‘breast hypoplasia’ that can cause low milk supply.
- Some mums had experienced low production in the early weeks after birth but were able to develop a full supply, while others were not able to increase their supply and had a low 24h measurement at ~3 months
- Many mums with low supply invested a lot of time and energy into trying to increase their supply, and said that getting help from a breastfeeding consultant was the most useful support.

Bottom line: Low milk production is complex and a common concern amongst breastfeeding mums. In many cases, it’s hard to explain or fully fix, so personalised help and more research are important.

One of the groups PhD students, Xuehua Jin, has just returned from a two-month research training in Vienna, thanks in part to receiving the ISRHML Trainee Expansion Programme Travel Award.

During this time, Xuehua trained with Professor Benedikt Warth’s team at the University of Vienna, where she gained extensive hands-on experience in liquid chromatography–mass spectrometry (LC-MS). Xuehua successfully measured a wide array of xenobiotics in human milk samples, generating a valuable dataset that will now be further analysed here at the UWA Centre for Human Lactation Research and Translation.

This work contributes to project goals by:
- Comparing detection rates and concentrations of xenobiotics between women with low vs. normal milk supply
- Investigating differences across maternal adiposity groups
- Estimating infant intake and exposure using milk intake data

Thanks to the team in Vienna, we look forward to advancing the data analysis in the coming months and uncovering new insights into maternal and infant health. Great work Xuehua! 😀

🤱 World Breastfeeding Week 2025: Supporting Breastfeeding After Caesarean Birth 🤱

Important research from our group in Australia sheds light on the unique challenges faced by families after caesarean birth - and what healthcare providers can do to help!

📊 The reality: Less than 50% of mothers who had caesarean births experienced skin-to-skin contact during their first breastfeeding attempt. Emergency caesareans particularly impacted both birth experience and breastfeeding initiation.

🚧 Key barriers identified:
• Pain and reduced mobility after surgery
• Rushed or conflicting care from staff
• Limited physical help with positioning baby
• Delayed first feeding opportunities

✨ What makes the difference:
• Unrushed, patient care from healthcare teams
• Full partner support - having your support person actively involved
• Physical assistance with lifting and positioning baby
• Early skin-to-skin contact when medically appropriate

💙 For families: If you've had or are planning a caesarean birth, know that breastfeeding IS possible! Advocate for:
• Partner presence and involvement
• Pain management that supports mobility
• Patient, individualized care
• Early breastfeeding support

Every birth story is different, and every feeding journey deserves support. Whether your baby arrived via caesarean or vaginal birth, planned or unexpected - you deserve compassionate care that helps you reach your breastfeeding goals!
