June 21 (UPI) -- New Zealand Prime Minister Jacinda Ardern gave birth Thursday to a baby girl -- becoming the second world leader to give birth while in office, and the first in more than a quarter-century.
Adern, 37, posted a photo online of the child, her first, with partner Clarke Gayford.
"Feeling very lucky to have a healthy baby girl that arrived at 4.45pm weighing 3.31kg (7.3lb) Thank you so much for your best wishes and your kindness. We're all doing really well thanks to the wonderful team at Auckland City Hospital," the post read.
Adern, elected in October, announced in January she was expecting a child.
Ardern, New Zealand's youngest prime minister since 1856, shared her thoughts about motherhood during an interview with Radio New Zealand.
"I am not the first woman to multi-task. I am not the first woman to work and have a baby; there are many women who have done this before," she said.
