Many new mothers worry about their milk supply. For some, support from a breastfeeding counsellor or lactation consultant helps.

Others cannot make enough milk no matter how hard they try. These are women whose breasts are not physically capable of producing enough milk.

Our recently published research gives us clues about breast features that might make it difficult for some women to produce enough milk. Another of our studies shows the devastating consequences for women who dream of breastfeeding but find they cannot.

Some breasts just don’t develop

Unlike other organs, breasts are not fully developed at birth. There are key developmental stages as an embryo, then again during puberty and pregnancy.

At birth, the breast consists of a simple network of ducts. Usually during puberty, the glandular (milk-making) tissue part of the breast begins to develop and the ductal network expands. Then typically, further growth of the ductal network and glandular tissue during pregnancy prepares the breast for lactation.

But our online survey of women who report low milk supply gives us clues to anomalies in how some women’s breasts develop.

We’re not talking about women with small breasts, but women whose glandular tissue (shown in this diagram as “lobules”) is underdeveloped and have a condition called breast hypoplasia.

We don’t know how common this is. But it has been linked with lower rates of exclusive breastfeeding.

We also don’t know what causes it, with much of the research conducted in animals and not humans.

However, certain health conditions have been associated with it, including polycystic ovary syndrome and other endocrine (hormonal) conditions. A high body-mass index around the time of puberty may be another indicator.

Could I have breast hypoplasia?

Our survey and other research give clues about who may have breast hypoplasia.

But it’s important to note these characteristics are indicators and do not mean women exhibiting them will definitely be unable to exclusively breastfeed.

Indicators include:

• a wider than usual gap between the breasts
• tubular-shaped (rather than round) breasts
• asymmetric breasts (where the breasts are different sizes or shapes)
• lack of breast growth in pregnancy
• a delay in or absence of breast fullness in the days after giving birth

In our survey, 72% of women with low milk supply had breasts that did not change appearance during pregnancy, and about 70% reported at least one irregular-shaped breast.

The effects

Mothers with low milk supply – whether or not they have breast hyoplasia or some other condition that limits their ability to produce enough milk – report a range of emotions.

Research, including our own, shows this ranges from frustration, confusion and surprise to intense or profound feelings of failure, guilt, grief and despair.

Some mothers describe “breastfeeding grief” – a prolonged sense of loss or failure, due to being unable to connect with and nourish their baby through breastfeeding in the way they had hoped.

These feelings of failure, guilt, grief and despair can trigger symptoms of anxiety and depression for some women.

One woman told us:

[I became] so angry and upset with my body for not being able to produce enough milk.

Many women’s emotions intensified when they discovered that despite all their hard work, they were still unable to breastfeed their babies as planned. A few women described reaching their “breaking point”, and their experience felt “like death”, “the worst day of [my] life” or “hell”.

One participant told us:

I finally learned that ‘all women make enough milk’ was a lie. No amount of education or determination would make my breasts work. I felt deceived and let down by all my medical providers. How dare they have no answers for me when I desperately just wanted to feed my child naturally.

Others told us how they learned to accept their situation. Some women said they were relieved their infant was “finally satisfied” when they began supplementing with formula. One resolved to:

prioritise time with [my] baby over pumping for such little amounts.

Where to go for help

If you are struggling with low milk supply, it can help to see a lactation consultant for support and to determine the possible cause.

This will involve helping you try different strategies, such as optimising positioning and attachment during breastfeeding, or breastfeeding/expressing more frequently. You may need to consider taking a medication, such as domperidone, to see if your supply increases.

If these strategies do not help, there may be an underlying reason why you can’t make enough milk, such as insufficient glandular tissue (a confirmed inability to make a full supply due to breast hypoplasia).

Even if you have breast hypoplasia, you can still breastfeed by giving your baby extra milk (donor milk or formula) via a bottle or using a supplementer (which involves delivering milk at the breast via a tube linked to a bottle).

Olympian Tom Daley is the most decorated diver in Britain’s history. He is also an avid knitter. At the Paris 2024 Olympics Daley added a fifth medal to his collection – and caught the world’s attention knitting a bright blue “Paris 24” jumper while travelling to the games and in the stands.

At the Tokyo Olympics, where Daley was first spotted knitting, he explained its positive impact on his mental health.

It just turned into my mindfulness, my meditation, my calm and my way to escape the stresses of everyday life and, in particular, going to an Olympics.

The mental health benefits of knitting are well established. So why is someone famous like Daley knitting in public still so surprising?

Knitting is gendered

Knitting is usually associated with women – especially older women – as a hobby done at home. In a large international survey of knitting, 99% of respondents identified as female.

But the history of yarn crafts and gender is more tangled. In Europe in the middle ages, knitting guilds were exclusive and reserved for men. They were part of a respected Europe-wide trade addressing a demand for knitted products that could not be satisfied by domestic workers alone.

The industrial revolution made the production of clothed goods cheaper and faster than hand-knitting. Knitting and other needle crafts became a leisure activity for women, done in the private sphere of the home.

World Wars I and II turned the spotlight back on knitting as a “patriotic duty”, but it was still largely taken up by women.

During COVID lockdowns, knitting saw another resurgence. But knitting still most often makes headlines when men – especially famous men like Daley or actor Ryan Gosling – do it.

Men who knit are often seen as subverting the stereotype it’s an activity for older women.

Knitting the stress away

Knitting can produce a sense of pride and accomplishment. But for an elite sportsperson like Daley – whose accomplishments already include four gold medals and one silver – its benefits lie elsewhere.

Olympics-level sport relies on perfect scores and world records. When it comes to knitting, many of the mental health benefits are associated with the process, rather than the end result.

Daley says knitting is the “one thing” that allows him to switch off completely, describing it as “my therapy”. https://www.youtube.com/embed/6wwXGOki–c?wmode=transparent&start=0

The Olympian says he could

knit for hours on end, honestly. There’s something that’s so satisfying to me about just having that rhythm and that little “click-clack” of the knitting needles. There is not a day that goes by where I don’t knit.

Knitting can create a “flow” state through rhythmic, repetitive movements of the yarn and needle. Flow offers us a balance between challenge, accessibility and a sense of control.

It’s been shown to have benefits relieving stress in high-pressure jobs beyond elite sport. Among surgeons, knitting has been found to improve wellbeing as well as manual dexterity, crucial to their role.

For other health professionals – including oncology nurses and mental health workers – knitting has helped to reduce “compassion fatigue” and burnout. Participants described the soothing noise of their knitting needles. They developed and strengthened team bonds through collective knitting practices. https://www.youtube.com/embed/dTTJjD_q2Ik?wmode=transparent&start=0 A Swiss psychiatrist says for those with trauma, knitting yarn can be like “knitting the two halves” of the brain “back together”.

Another study showed knitting in primary school may boost children’s executive function. That includes the ability to pay attention, remember relevant details and block out distractions.

As a regular creative practice, it has also been used in the treatment of grief, depression and subduing intrusive thoughts, as well countering chronic pain and cognitive decline.

Knitting is a community

The evidence for the benefits of knitting is often based on self-reporting. These studies tend to produce consistent results and involve large population samples.

This may point to another benefit of knitting: its social aspect.

Knitting and other yarn crafts can be done alone, and usually require simple materials. But they also provide a chance to socialise by bringing people together around a common interest, which can help reduce loneliness.

The free needle craft database and social network Ravelry contains more than one million patterns, contributed by users. “Yarn bombing” projects aim to engage the community and beautify public places by covering objects such as benches and stop signs with wool.

The interest in Daley’s knitting online videos have formed a community of their own.

In them he shows the process of making the jumper, not just the finished product. That includes where he “went wrong” and had to unwind his work.

His pride in the finished product – a little bit wonky, but “made with love” – can be a refreshing antidote to the flawless achievements often on display at the Olympics.
