On the same day New Zealand made big strides towards outlawing military-style guns, smaller steps were being made at the home of the Prime Minister.
Stay-at-home dad Clarke Gayford says Neve Te Aroha Ardern Gayford has begun crawling.
"For her 9 month birthday today we received the gift of crawling," he posted on social media site Twitter on Thursday night. "While her mum got her the gift of having a safer country to grow up in."
Earlier that day, Jacinda Ardern announced changes to the country's gun laws that will see potentially hundreds of thousands of firearms made illegal.
The announcement came six days after a gunman opened fire in two Christchurch mosques, killing 50 and injuring 50 more.
Neve Te Aroha was born on June 21, 2018. Ardern was the first New Zealand Prime Minister to give birth while in the nation's top job.
Responses to Gayford's tweet were a mixture of congratulations and tongue-in-cheek warnings from other parents.
"Congratulations Neve on your milestone. And thank you for letting us all borrow your mum so much this last week," said @SkarsgardsKiwi.
"If Neve is anything like her mum, that baby is gonna be one amazing woman," said @NozainN.
"I trust she consulted a committee of advisors before taking any important steps.... Sorry couldn't resist," joked @MayaOfAuckland.
