You can get paid for breast milk by donating to a for-profit milk bank, which typically pays between $1 and $4 per ounce. The most established route is through corporate donor programs that collect milk for premature and medically fragile infants. There are also peer-to-peer selling platforms, though these carry significant safety and legal concerns.
For-Profit Milk Banks: The Most Common Route
For-profit milk banks are companies that purchase breast milk, pasteurize and process it, then sell specialized products (like shelf-stable milk and fortifiers) to hospitals for premature babies. These companies pay donors directly and handle most of the logistics for you.
Prolacta Bioscience, through its Tiny Treasures Milk Bank program, is the largest and most well-known for-profit buyer. They currently pay $1.20 per qualified ounce. That may sound modest, but if you’re consistently producing a surplus, it adds up. A parent pumping an extra 20 ounces a day could earn roughly $700 a month. The broader market range across for-profit companies runs from about $1 to $4 per ounce, depending on the buyer and volume.
Non-profit milk banks, by contrast, do not pay for milk. Organizations affiliated with the Human Milk Banking Association of North America (HMBANA) only reimburse expenses like shipping costs and storage bags. If your goal is specifically to earn money, you’ll want to focus on for-profit programs.
What the Screening Process Looks Like
Every legitimate milk bank requires health screening before accepting you as a donor. The process generally involves three steps: a phone interview, a written health history signed by your healthcare provider, and blood work. The blood tests screen for HIV-1, HIV-2, HTLV (a rare virus that can pass through milk), hepatitis B, hepatitis C, and syphilis.
You’ll typically be disqualified if you use tobacco, regularly drink alcohol, take certain medications, or have a history of specific infections. Each company has its own detailed list of exclusions, so it’s worth applying even if you’re unsure. The screening is free, and most programs walk you through every step.
How Storage and Shipping Work
Once you’re approved, you’ll pump and freeze your surplus milk at home. Proper storage is critical, both for the baby who will eventually receive it and for your milk to pass quality checks. Milk stored in a standard home freezer (at 5 to 15 degrees Fahrenheit) stays viable for about six months. A deep freezer set to 0°F or below extends that to 12 months. Avoid storing milk in the door compartment of your freezer, where the temperature fluctuates every time you open it.
Many for-profit programs provide shipping supplies or arrange pickup. If you’re shipping yourself, the milk needs to stay frozen throughout transit. That means packing it in a cooler with about two pounds of dry ice, layered with newspaper for insulation. Seal the milk in zip-lock bags first, then nestle them on top of the insulated dry ice. Label the cooler inside and out with your name and donor ID. If shipping by air, you’ll need to declare the dry ice as a hazardous substance and note that the contents are a bodily fluid, per airline regulations.
Peer-to-Peer Selling: Higher Pay, Higher Risk
Some parents skip the milk bank entirely and sell directly to other families through online classified sites. Prices on these platforms tend to be higher, sometimes $3 to $4 per ounce or more, because the buyer is purchasing directly without a corporate middleman.
The safety concerns here are serious, though. A study from Nationwide Children’s Hospital found that 75 percent of breast milk samples purchased online contained bacteria at levels high enough to cause illness in infants. Researchers found fecal contamination in multiple samples, likely from poor hand hygiene, and even detected salmonella in a few. Nearly one in five sellers didn’t include any cooling method in their shipment, meaning the milk arrived at unsafe temperatures. Buyers on these platforms have no way to verify whether the seller’s health information is truthful, whether the milk has been handled hygienically, or whether it contains drugs or medications.
The FDA recommends against feeding infants breast milk obtained through informal sharing or online sales. Milk banks registered with the FDA are inspected as food manufacturers and must comply with federal food safety standards. Peer-to-peer sales have none of those safeguards. If you choose this route, understand that you’re operating in a largely unregulated space, and both you and the buyer assume the risk.
Steps to Get Started
- Check your supply. Most programs want donors who produce a consistent surplus beyond what their own baby needs. You don’t need to be producing massive quantities, but a few extra ounces a day is a realistic minimum.
- Apply to a for-profit program. Tiny Treasures (Prolacta Bioscience) is the easiest starting point. Their application is online, and they’ll guide you through the phone screening and blood work.
- Get your provider’s sign-off. You’ll need your doctor or midwife to review and sign a health history form confirming you’re a good candidate.
- Complete blood work. Some programs arrange this at a specific lab; others send you to a local draw site. Results typically come back within a couple of weeks.
- Start pumping and freezing. Once approved, freeze your surplus in the bags or containers the program specifies. Keep your pump parts and storage containers clean, and wash your hands thoroughly before every session.
- Ship on schedule. Most programs set up recurring shipments. Follow their packaging instructions exactly to avoid having milk rejected for temperature issues.
Realistic Earnings
At $1.20 per ounce through Prolacta, the math depends entirely on how much surplus you produce. Someone pumping an extra 10 ounces per day earns about $360 a month. At 25 extra ounces per day, that’s closer to $900. These numbers assume every ounce qualifies. Milk can be rejected if it arrives thawed, if it was stored too long before shipping, or if it doesn’t meet quality testing standards.
The earning window is also limited to however long you’re breastfeeding and overproducing. Most donors participate for somewhere between 3 and 12 months. It’s supplemental income, not a salary, but for parents already producing more than their baby drinks, it turns a freezer full of milk into money while helping premature infants who need it.
