A Gift That Goes Beyond Your Own Baby: Understanding Donor Breastmilk and Human Milk Banking
October is a wonderful time to talk about something that doesn’t always get the attention it deserves: donor breastmilk and human milk banking.
For some mothers, breastfeeding comes with an unexpected bonus, they find themselves producing more milk than their own baby needs. There may be a freezer slowly filling with bags of milk, or perhaps you are regularly expressing and wondering what to do with the extra.
Instead of letting that milk go to waste, there may be another option: donating it to a human milk bank. It is a beautiful way for one mother to support another family, and potentially make a real difference to a tiny baby who needs it.
Why does donor milk matter?
Human milk banking exists primarily to support babies who are particularly vulnerable, including premature or medically fragile babies whose own mother's milk is temporarily unavailable or insufficient. For these babies, human milk can be especially valuable. Their little bodies are still developing, and breastmilk provides nutrients as well as components that support their immune system and gut health.
Donor milk is not simply collected and handed to another baby. There is a carefully controlled process behind every donation. Donor mothers are screened, milk is collected and stored according to the bank's requirements, and donated milk is processed and pasteurised before it is supplied to eligible babies. HMBASA provides guidance for human milk banking centres in South Africa, including standards around the collection, handling and processing of donor milk.
So, yes, that bag of milk in your freezer really can become part of something much bigger.
Could I be a breastmilk donor?
This is one of the most common questions mothers ask. The answer is: possibly!
Milk banks have specific screening criteria, so being a breastfeeding mother with extra milk does not automatically mean you will be accepted. Each bank will assess your circumstances and guide you through its screening process.
Individual milk banks may have their own requirements and processes, so always check with the milk bank before assuming you are eligible. And perhaps most importantly: you don't need to be producing litres and litres of milk to have a meaningful conversation about donation. If you have a genuine oversupply and your baby is well fed and growing appropriately, speak to a milk bank about whether donating may be an option for you.
What happens after you decide to donate?
The process may look slightly different depending on which milk bank you use, but it generally starts with screening. You may be asked about your health, lifestyle, medications and breastfeeding journey. Blood tests may also form part of the screening process. Once approved, the milk bank will provide guidance on expressing, storing and transporting your milk.
Your milk is then handled according to the bank's safety procedures. For example, HMBASA describes a process where donated milk is screened, frozen, collected and then pasteurised before being frozen again until it is needed.
This is important because donor milk is intended for vulnerable babies. Safety comes first.
Where can you donate in South Africa?
There are several human milk banking services and networks around the country.
South African Breastmilk Reserve (SABR)
SABR supports breastmilk donors across South Africa. You don't necessarily have to live close to a milk bank, depending on your location, collection from your home, a local drop-off point, a partner facility or courier arrangements may be possible.

Netcare Ncelisa Human Milk Banks
Netcare's Ncelisa programme provides screened and processed donor breastmilk to eligible premature and medically vulnerable babies in neonatal intensive care. Netcare currently has milk banks and collection sites through its network, with donated milk supporting babies in both private and public-sector hospitals.
Milk Matters
For mothers in Cape Town and surrounding areas, Milk Matters is a community-based milk bank with depots throughout the Western Cape. Mothers can use these depots to collect sterile containers or drop off frozen breastmilk.
Human Milk Banking Association of South Africa (HMBASA)
HMBASA is an independent non-profit organisation that provides guidance to human milk banking centres across South Africa and promotes standards and best practice in human milk banking. Its website also provides information about milk donation and links to milk banks.
And where does SACLC fit in?
A question we often hear is: "Can my lactation consultant help me with donating milk?" Absolutely, while the milk bank itself is responsible for assessing and approving donors, a trained SACLC consultant can be an important source of breastfeeding and expressing support along the way.
For example, a lactation consultant can help you understand whether what you are experiencing really looks like an oversupply, support you with comfortable and effective milk expression, talk through your baby's feeding and growth, and help you navigate concerns about pumping, storage or maintaining your own breastfeeding relationship. This is particularly important because donation should never come at the expense of your own baby.
Your baby's needs come first.
If you're expressing huge amounts because you're trying to "build a stash", experiencing discomfort, or pumping much more than your baby needs, it's worth speaking to a trained lactation consultant before simply deciding to donate everything.
A few things to remember before donating
Don't compare your donation to someone else's.One mother may donate a few hundred millilitres while another donates several litres. Every approved donation can contribute to the milk bank's supply.
Don't pump simply to become a donor.Donation is generally intended for mothers who have excess milk. Your own baby's nutritional needs and your breastfeeding relationship should remain the priority.
Don't donate privately to another baby without appropriate screening and safety processes.Human milk banking exists for a reason. Milk intended for vulnerable babies needs to be carefully screened, processed, stored and tracked.
Speak to your healthcare team if you have questions.Your lactation consultant, midwife, doctor or the milk bank itself can help you work out what is appropriate for your circumstances.
Ask. Learn. Get screened. And if you're eligible and it feels right for you, consider giving your extra milk a second life. Because sometimes, one mother's "extra" can be another baby's much-needed gift.
