36-year-old Alyse Ogletree now holds the unique record for largest donation of breastmilk by an individual with an incredible 2,645.58 litres (89,457.85 US fl oz; 93,111.55 UK fl oz) as of July 2023.

"The 36-year-old, from Texas, first broke the record back in 2014 with a measurement of 1,569.79 litres (53,081 US fl oz; 55,249 UK fl oz)," reads the Guinness World Record website.

Alyse Ogletree said she always felt happy that she was able to help others with her donated milk.

“I have a big heart,” she told the Guinness World Record website.

 “At the end of the day, I’m not made of money and I can’t give away money to good causes over and over because I have a family I have to support for," she said.

She added: “If the three per ounce is accurate, I’ve helped over 350,000 babies. This record is for just under 89,000 ounces, but I also did around 37,000 to Tiny Treasures, and probably another couple hundred to close friends.”

She started donating breastmilk for the first time when she gave birth to her first child in 2010.

“Our first child, Kyle, was in the hospital, and I was filling the nurses’ freezer. A nurse asked if I was donating, which I didn’t know was possible, and that is when I learned about it," she said.

“I ended up donating everything I had saved up to that point and continued to donate for a bit," she said.

Shaina Starks, executive director of Mothers’ Milk Bank of North Texas, told the website: “Alyse Ogletree has astounded and inspired us once again through her remarkable commitment to donate an incomprehensible amount of surplus breastmilk to fragile infants. Her life-saving efforts are an undeniable testament to her extraordinary generosity and compassion.”
