A 30-year-old transgender man, Kaci Sullivan, has become the first person in the world to give birth while living as both genders, four years after he began the transition from female to male, after welcoming a baby, 5 years after having his first child as a woman.
The business student conceived with partner Steven, 27, after a break from taking male hormones. He underwent a C-section following seven days in labour before welcoming Phoenix, who weighs a healthy 8lbs 9oz.
The couple have not revealed the baby's sex and say the child will be raised as 'gender neutral' until being old enough to decide its sexuality. Kaci already had one child, five-year-old Grayson, with his ex-husband, who he gave Birth to while living as a woman before coming out as Transgender. 📸: SWNS
