NZ's First Baby is taking over the United Nations Summit!

While PM Jacinda Ardern has been out making speeches at the United Nations in New York, New Zealand's First Baby Neve has been making headlines around the world.

Clarke Gayford has taken on super Dad duties, making sure baby Neve is happy (and quiet) while she watches her Mum make waves at the UN, but it's taken a toll.

Gayford addressed the "concerned messages" about how tired he was looking, in a tweet.

"Thank you for the concerned messages about how tired I look (fair call). Seems 'someone' is determined to maintain [NZ time].

 "We've watched so much bad late-night TV together that her mum came out at 2am and busted us watching cage fighting in our underpants."

Yesterday, he also tweeted about Neve's time at the UN, saying staff had even whipped up an ID card for her.

"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."

Potentially a good story for her 21st!

A United Nations spokesman, Stephane Dujarric, said the organisation was delighted to see Neve in the General Assembly hall.

“Prime Minister Ardern is showing that no one is better qualified to represent her country than a working mother,” he said.

“Just five per cent of the world’s leaders are women, so we need to make them as welcome here as possible.”
