New Zealand Prime Minister Jacinda Ardern gave birth to a baby girl in an Auckland hospital on Thursday, becoming only the second world leader to do so while in office.

The charismatic Ardern follows Pakistan’s prime minister Benazir Bhutto in 1990 as the only women in modern history to give birth while in power but she downplayed the significance when she announced her pregnancy earlier this year.

“Lots of people juggle a lot of things in their personal and private lives, and I’m not unusual in that. Plenty of women have multitasked before me, and I want to acknowledge that,” she said when announcing her pregnancy in January.

Incidentally, Ardern’s newborn daughter shares a birthday with Bhutto.

Pakistan’s Bhutto, who was assassinated in 2007, gave birth in January 1990 to her daughter Bakhtawar Bhutto Zardari, who now describes herself on Twitter as the “1st child born to a sitting female Prime Minister”.

Bakhtawar tweeted “congratulations” to Ardern after the announcement, and shared a link to a news story on how Bhutto showed it was possible to be a mother and a prime minister.
