“We were talking and Brad told me he had a thing for big-breasted women, and that size had always been a factor in his relationships,” Mulford said. “I thought it was the perfect time to bring up adult breastfeeding — and see if he’d be interested.”

It was “like a light switch flicked in [Leeson’s] head,” Mulford said. Before long, Leeson was doing his own research on ABR.

“At that moment I knew that I had a partner for life,” Mulford said. “We both wanted the same thing out of the relationship — a magical bond that only breastfeeding can achieve.”

Mulford said it’s been 20 years since she gave birth and last breastfed, and said the process involves pumping and dry feeding to get her body to begin producing milk.

In a 2012 Reddit “Ask Me Anything” thread, a woman in an adult breastfeeding relationship answered users’ curious questions, and insisted the practice is “not infantilism.” The woman, posting under the online handle “sassymilkmaid,” explained that “it’s both sexual and emotional” for her boyfriend.
