This grown woman just wants to be a baby.

Jess, a 21-year-old based in Lakeland, Fla., loves to wear nappies, drink from sippy cups, and sleep in an oversize cot pretending she’s an infant. She also role-plays with her 24-year-old boyfriend, David, whom she calls “Daddy.” As a sexual-abuse survivor, Jess says this has helped her make peace with her past.

“Age play is really my best escape, and it allows me to reclaim the innocence of my childhood and have it play out the way I always wanted,” Jess tells Barcroft. “Aside from that, though, regressing and being ‘little’ just fits with my personality.”

Jess and David have been together for four years and engage in a practice known as Daddy Dominant/Little Girl, which is a type of BDSM relationship. She wears animal-printed PJs and sometimes urinates in her diapers.

“For us, it is more about enjoying the dominant/submissive dynamic in our everyday lives,” she continues. “I enjoy the feeling of David being a protector and a person that I can depend on to look after me and he likes feeling needed.”
