for mothers with more milk than they expected
Do you have more milk than your baby needs?
You've been pumping faithfully, sometimes at 2am, and you’ve built up an impressive freezer stash. If you're wondering what you might need and what to do with the rest, you are not alone. There's an answer, and it's a good one.
Extra Milk Isn’t Always an Oversupply
Extra Milk Happens for Many Reasons
Extra milk happens for many reasons. Milk production runs on supply and demand, so when more milk leaves than your baby drinks, your body reads that as demand and keeps right up. Many moms simply make a little more than their baby needs, or have milk left over during weaning or after feeding patterns change.
what a small daily surplus becomes
4 oz a day → 120 oz a month
You may not notice a few extra ounces a day, until the day the freezer won't shut. Over a month that's about 20 bags. Over six months it's a lot of freezer space.

Check the ones that sound familiar. Most moms with extra milk find they're nodding at more than one.

Nothing here is saved or sent anywhere. It's just for you.
the part that's easy to miss
This is real work, and you’re doing it.
Having extra milk – whether from your natural capacity, your pumping rhythm, or the changes that come with weaning – can be a lot to manage. The fullness, the washing and labeling, often on very little sleep, is a labor of love. You’re producing something precious to nourish your baby – and maybe enough extra to help other families who can’t.
Most moms who reach the end with a full freezer don't regret the pumping. They regret finding out it could have made a lifesaving difference. They regret losing any of that hard work after it was too late.
When you're ready to see what happens to milk that gets donated: Who receives donor milk
questions donors ask
The things most moms want to know first.
Do I have to donate a certain amount?
No. Whether you have a full freezer, or plan to give a little at a time across your whole breastfeeding journey, every ounce counts. One ounce provides up to three feedings for the tiniest NICU warriors.
Can I donate milk I've already pumped?
Usually, yes. If you recorded the pump date on your storage bags, milk can typically be donated up to nine - twelve months from that date when it has been stored properly in a freezer. Your donor specialist reviews the storage guidelines with you and flags any exceptions based on your health questionnaire.
Do I have an oversupply?
Extra milk does not necessarily mean clinical oversupply.
If persistent fullness, recurrent clogs, pain, or feeding difficulties are part of what you are experiencing, an IBCLC (International Board Certified Lactation Consultant) or your healthcare provider can help you assess what is happening and what to do next.
How long does the process take?
Most donors go from first contact to first donation in about 20 days, and many donors finish in half that time. You can move faster still by scheduling your blood draw early and letting your doctor know to expect a fax from The Milk Bank. The steps exist to meet every safety and health check, so a fragile baby can receive the milk with confidence.
Why is there a cost for donor milk?
The Milk Bank never profits from your generous donation. The cost covers the screening, testing, pasteurization and cold chain that turn a gift of milk into medicine safe enough for the most fragile babies. Hospitals pay this processing fee similar to blood donations, and outpatient families have access to a Medical Relief Fund based on need.
What happens to my milk after I donate it?
It becomes lifesaving nutrition. After intake, your milk is weighed, recorded under your Donor ID, and kept frozen. In the lab it is analyzed, pooled with milk from other donors, portioned, sealed, bar-coded, and pasteurized to remove any harmful bacteria. One bottle from each batch is sent offsite for a final microbiological test. Once approved, the pasteurized donor milk goes to babies in hospitals and at home.
Where do I actually drop it off?
There are Milk Depots across the community, so there may be a site near your home or work. If not, The Milk Bank ships you the supplies to send it in at no cost to you.
Still have a question that isn't here? Email milkdonor@themilkbank.org, book a call with a donor specialist, or phone 317.536.1670 and ask for donor relations.
when you're ready
Your baby always comes first.
Screening is free, and so is the lactation support that comes with it – including milk storage bags if you need them. Most donors are approved in about 20 days, and many finish in half that time. Every ounce counts, and the milk in your freezer could be the reason a baby goes home. Not sure yet? See your options for extra milk.
