World Record for Donating Breast Milk

Elisabeth holds a Guinness World Record for the largest breast milk donation by an individual. In just three years, she donated an astounding 1,599.68 liters (or 422.59 gallons) of breast milk. To put it into perspective, that’s like filling 800 two-liter soda bottles or making over 2,200 Starbucks Venti lattes! And this doesn’t even include the milk she gave to families around the world. Over the course of nine years, Elisabeth estimates that her total milk donations have exceeded 350,000 ounces. That’s an astonishing amount of milk!

Hyperlactation Syndrome: The Rare Condition Behind the Supermom

Elisabeth’s story isn’t just about giving; it’s about overcoming a rare medical condition known as hyperlactation syndrome, which causes her to produce far more milk than the average person. Every day, she produces over 6 liters (1.75 gallons) of milk—an extraordinary amount that presents both challenges and opportunities.

This condition makes her journey through motherhood quite different from most. Elisabeth has become a local hero in Beaverton, Oregon, where people have affectionately dubbed her the “Milk Goddess” due to her unmatched ability to produce milk. Despite this, Elisabeth remains humble: “I’m just a mom with a gift I can share,” she says.

The Story of Baby Joaquin: A Heartwarming Example of Generosity

One of the most touching moments in Elisabeth’s journey was her trip to Puerto Rico after Hurricane Maria in 2017. While there, she met baby Joaquin, a three-month-old preemie who had tragically lost his mother during childbirth. His father was struggling to feed him, relying on expensive formula and milk bank shipments. When Joaquin thrived on Elisabeth’s breast milk, she promised to send him milk for an entire year.

This is just one of many heartwarming stories where Elisabeth’s milk donation has saved lives. She isn’t just a mother to her own three kids; she’s a mother to many others across the globe.

The Demanding Task of Pumping Breast Milk

Pumping breast milk isn’t easy for Elisabeth. Every day, she spends 4 to 5 hours hooked up to pumps, a process that requires dedication and skill. “Pumping is like an Olympic sport, and I’m an elite athlete, but it’s not fun. My breasts wake me up in the morning because they’re screaming, ‘Please do something about this!'” she admits. It’s clear that producing that much milk is a physically demanding task that comes with its own set of challenges, including pain, sleepless nights, and the constant pressure to maintain her milk supply.

Despite these difficulties, Elisabeth is driven by a mission much larger than her own family. She’s a dedicated donor, sharing her milk with moms in need, milk banks supporting premature babies, and even gay couples who need help.

Donating More Than Just Milk: Elisabeth’s Impact on the Community

Over the past three years, Elisabeth has donated an incredible 700 gallons of milk—double the previous world record. Her contributions have become a vital resource for the community, especially for families who need milk for their preterm babies.

Running this one-woman dairy operation isn’t cheap. Elisabeth has invested in pumps, supplies, and even electricity to keep her four freezers running. Although she earns $1 per qualified ounce of donated milk, it barely covers her expenses. “I’m not making bank here. It just helps me keep going,” she explains.

Personal Sacrifice: The Cost of Being a Supermom

Elisabeth’s journey isn’t just about the milk. It also requires significant personal sacrifice. She hasn’t had a day off in over two and a half years, and her work is far more than a full-time job. Yet her commitment remains unwavering, driven by the desire to help others.

“I’m not out to make a profit. People think I’m making a fortune, but really, it just helps sustain what I do,” Elisabeth shares. Despite the exhaustion, she’s determined to continue her mission, regardless of the physical toll it takes.

The Power of Love, Sacrifice, and Community

Elisabeth’s story is a powerful testament to the impact that rare conditions like hyperlactation syndrome can have when used for good. Through her excess milk production, she’s touched the lives of countless people, demonstrating the strength of love, resilience, and community.

“This is my way of being active in my community and giving back to humanity. It’s my labor of love,” she says. Elisabeth believes that if everyone shared this kind of mentality, the world would be a much better place. And for now, she’s determined to do her part, one ounce at a time.

Can She Pump Forever? Elisabeth’s Future Plans

Though Elisabeth is committed to her cause, she knows she can’t pump forever. She’s exploring options to reduce her prolactin levels, including medications or even a double mastectomy to stop milk production altogether. “Removing the glandular tissue would stop production, but there’s always the risk of new breast tissue forming due to hormones,” she notes.

But for now, Elisabeth is not slowing down. She is humbled by her Guinness World Record and hopes that her story will inspire others to normalize milk sharing. “I really hope that breaking this record and sharing my story will help normalize milk sharing,” she says proudly.

Frequently Asked Questions About Breastfeeding

How long should I breastfeed my baby?

Health organizations like the World Health Organization and the American Academy of Pediatrics recommend exclusive breastfeeding for the first six months of a baby’s life. After that, breastfeeding should continue alongside appropriate complementary foods until at least two years or longer, depending on the mother and child’s preferences.

How often should I breastfeed my newborn?

Newborns typically need to be fed 8–12 times per day during the first month. Breast milk is easily digested, so frequent feedings ensure the baby gets enough nutrition and helps stimulate milk production.

How can I tell if my baby is getting enough milk?

Signs your baby is getting enough milk include regular weight gain, frequent wet and dirty diapers, and appearing satisfied after feedings. If you have concerns, consult a healthcare provider or lactation consultant.

What are some common breastfeeding challenges and solutions?

Some challenges include sore nipples, engorgement, and low milk supply. Solutions include ensuring proper latch, using lanolin cream, applying warm compresses before feeding, and consulting a lactation consultant if necessary.

Can I breastfeed if I’m sick or taking medication?

In most cases, breastfeeding can continue if you’re ill, as your body produces antibodies that protect your baby. However, always check with your healthcare provider before taking new medications.

How do I store expressed breast milk?

Breast milk can be stored at room temperature for up to 4 hours, in the refrigerator for up to 4 days, and in the freezer for up to 6 months. Always label milk with the date it was expressed and use the oldest milk first.
