A Name, A gift, And A Case Of Baby Brain: Jacinda Ardern

Welcome to the world, baby Neve!

New Zealand Prime Minister Jacinda Ardern has left hospital with her baby daughter, saying her newly expanded family is “sleep-deprived but super well”.

Ardern spoke briefly to media outside Auckland City Hospital on Sunday alongside her partner Clarke Gayford, revealing the name they had chosen was Niamh Te Aroha Ardern Gayford -- or Neve Gayford for short.

The name has Irish origins, and means in various forms “bright”, “radiant” and “snow”.

Ardern explained Te Aroha was a rural town in the Waikato region of New Zealand where her family is from.

"Te Aroha ... was our way of reflecting the amount of love this baby has been shown before she even arrived," she said.

Proving that she's not that different from mums everywhere, Ardern had the briefest moment baby brain, accidentally referring to Prince Harry and Meghan Markle as the Duke and Duchess of Essex. Though actually the Duke and Duchess of Sussex, today, the PM could be forgiven.

Arden became New Zealand’s first female leader to give birth while in power on Thursday.

It’s the couple’s first child together, and comes eight months after the 37 year old was sworn in as Prime Minister.

“It’s a real pleasure to introduce our little one to you all and to New Zealand,” Ardern said on Sunday, thanking both hospital staff and members of the public for their “kindness, warmth and care” over the course of her pregnancy.

“The kindness has been overwhelming. We just want to thank the members of the public who have sent us messages of kindness and best wishes,” the Prime Minister said.

“To me, in those moments, we just saw a reflection of how open and generous New Zealanders are.”

Arden is the first elected world leader to take maternity leave, handing over the reigns to Deputy Prime Minister Winston Peters for six weeks, and only the second to have a child while in office -- both roles she has spent months downplaying.

"I do not want to create a false impression that all women should be super-human or superwomen,” Ardern said recently. And to another local TV station: "The thing to keep in mind is: I'm not dead."

Along with our well-wishes, Australia gifted the newest family member a pair of RM Williams booties.

Made of Kangaroo leather and retailing at $145, here's hoping little Neve's feet don't grow too quickly.
