'A full-time job': Oregon mom's record-setting breastmilk production helps kids worldwide


It took 958 days to pump.

And thousands of newborns are alive thanks to her selfless work.

Elisabeth Anderson-Sierra, a 35-year-old mother of three from the West Coast, is a Guiness World Record breaker for gifting more than 350,000 ounces of her own breastmilk to premature babies around the world.

The Aloha, Oregon, resident set the record for the largest donation of breastmilk by an individual by donating nearly 1,600 liters to a milk bank between February 2015 and June 2018. 

Per Guinness, that’s the equivalent to 800 2-liter bottles of Coke.

Eight. Hundred. Bottles.

“I’ve donated more since that record too – at least 10,000 ounces more,” she told USA TODAY Thursday.

Elisabeth Anderson-Sierra, 35, is a mom of three with hyperlactation syndrome and has broken a Guiness World Record after donating more than 350,000 oz. of breast milk to premature babies around the world. She lives in Oregon with her husband and three children.

A blessing and a curse

Anderson-Sierra, has hyperlactation syndrome, a diagnosis she called both a blessing and a curse.

According to the National Institutes of Health (NIH) the syndrome is a condition where breast milk overflow occurs because of increased milk production.

“My body creates a significant amount of the hormone called prolactin which drives milk production,” Anderson-Sierra said.
