In October 2017, at age 37, New Zealand politician Jacinda Ardern became the country's youngest prime minister in more than 150 years. At the time, she was questioned about her plans to have children, and she took a stand about the double standard that faced women of child-bearing age in jobs and positions of power. Coincidentally, she then governed for her first eight months while pregnant: in June 2018, Ardern gave birth to her first child, making her the first leader of a country in nearly 30 years to give birth while in office, according to Britannica.
