When Alecia-Jane Twigger gave birth to her first child last year, she encountered unexpected emotional and practical challenges with breastfeeding despite growing up in a family where it was normalized. The experience was demanding, requiring multiple hours of feeding daily and accompanied by feelings of overwhelm driven by hormonal responses. Twigger, who founded the Cambridge Lactation Lab in 2024 to advance research on human milk, found the support system inconsistent. While some groups and NHS services provided useful aid, others offered outdated advice or were stretched too thin to help effectively.
Historically, the UK has had low breastfeeding rates compared to other countries, but recent data shows improvements. The latest infant feeding survey for England in 2024 indicated that 58 percent of women breastfeed to some extent at six months, up from 36 percent in 2010. Exclusive breastfeeding at this age increased from 1 percent to 26 percent, though survey limitations suggest this may not represent the full population. Notably, a significant proportion of women—72 percent in 2024—stop breastfeeding earlier than they wished, often citing perceived low milk supply.
Recent scientific research is beginning to explore potential biological reasons behind low milk supply, a subject that has historically been underinvestigated. Studies from the United States, Australia, and the UK have identified factors including enzyme deficiencies, chronic inflammation related to conditions such as obesity and diabetes, genetic influences, and impacts from rising cesarean section rates. Innovative tools, such as sodium-level measuring electrodes in breast milk, have been developed to detect early signs of supply issues. These findings challenge longstanding assumptions, suggesting that between 10 and 20 percent of women may face physiological barriers to milk production, higher than previous estimates of 2 to 5 percent. This raises important questions about whether some mothers have been unfairly blamed or made to feel inadequate.
Psychological aspects of breastfeeding also receive attention. Professor Amy Brown of Swansea University studies the emotional toll, including grief and shame, experienced by women who struggle. She emphasizes that the lack of clear diagnostic tests stands in contrast to other medical issues and highlights the coexistence of physiological and support-related problems. Support variability remains a concern, with disparities between regions and service providers. Some NHS areas, such as Hull, have seen increases in breastfeeding rates through coordinated efforts that combine professional and volunteer support, but inconsistency persists nationally. This has led many women to seek private consultants, often at significant personal cost.
Experts agree that breastfeeding difficulties often stem from a complex interplay of biological and social factors. There is ongoing debate about the effectiveness of common interventions like triple feeding—a demanding combination of breastfeeding, pumping, and bottle feeding—and the potential impact of gestational diabetes and maternal BMI on milk supply. Research continues into diverse topics such as environmental effects on breastfeeding in different climates and the influence of breast milk on the infant gut microbiome.
Advocates argue that greater investment in trained professionals and consistent, evidence-based support is essential. Legislation currently progressing in the UK Parliament—the Infants, Parents and Carers Bill—aims to increase resources for breastfeeding support akin to the Sure Start centres phased out in 2010. For mothers like Twigger, having a biological diagnosis for low milk supply could reduce stigma and guilt, offering opportunities for early intervention in future pregnancies. While scientific advances provide hope, the critical missing element remains accessible, informed support to turn knowledge into practical help for new mothers.
