With a mock security pass that lists her as the "First Baby" of New Zealand, three-month-old Neve Te Aroha has made her United Nations debut when her mother - Prime Minister Jacinda Ardern - spoke at a peace summit in the General Assembly.
Her partner Clarke Gayford, who is the baby's full-time caregiver, sat with the New Zealand delegation and held Neve as Ardern spoke in New York on Monday.
Ardern (38) is only the second elected leader to give birth while in office, after Pakistan's Benazir Bhutto in 1990.
Gayford posted a photo on Twitter of Neve's security pass for the annual gathering of world leaders in New York this week.
He added: "I wish I could have captured the startled look on a Japanese delegation inside UN yesterday who walked into a meeting room in the middle of a nappy change. Great yarn for her 21st (birthday)."
Ardern is New Zealand youngest Prime Minister and the first to take maternity leave while in office.
The United Nations was delighted to see baby Neve in the General Assembly hall, UN spokesman Stephane Dujarric said.
"Prime Minister Ardern is showing that no one is better qualified to represent her country than a working mother. Just 5 percent of the world's leaders are women, so we need to make them as welcome here as possible," he said.
Ardern is breastfeeding and cannot be away from her baby for extended periods She was grateful for Gayford's help.
"I'm lucky. I have an incredible support network around me. I have the ability to take my child to work. There’s not many places you can do that," Ardern told a Social Good Summit in New York on Sunday.
"Unless there is a culture that accepts that mothers and children are part of our workplaces, then we won't change anything. So if I can do one thing and that is just change the way we think about these things, then I will feel pleased that we have achieved something," she said.
When the event moderator remarked that the baby was backstage and very peaceful, Ardern quipped: "Wasn't at 3:30 this morning."
