Elisabeth Anderson-Sierra, based in the US, has made an incredible impact on the lives of premature babies.

With hyperlactation syndrome causing her to produce excess breast milk, she holds the world record for the largest individual donation of breast milk.

Since February 2015, Elisabeth has been donating to a milk bank, benefiting countless infants.

In a heartwarming video shared by Guinness World Records on Instagram, Elisabeth showcases her dedication.

She estimates donating over 350,000 ounces in the past nine years.

Though she admits the condition is challenging, she remains committed to helping others.

With bottles filled to the brim, Elisabeth shares that her milk production occurs every few minutes.

She has donated locally and worldwide, particularly focusing on infants labeled as "failure to thrive."

Witness the incredible journey of a selfless mother providing nourishment and hope to those in need.
