The father who live streamed his wife giving birth didn't actually realise the whole world could see.

Have you ever accidentally posted something to Facebook?

A photo you didn’t realise had something embarrassing in the background?

Your child – playing with your phone – has pressed the post button after snapping off a video of their little brother on the potty?

The accidental “like” when you were snooping on your ex’s new partner?

What about accidentally live streaming the birth of your child?

Whoops.

The birth was watched around the world. Via Facebook.

That’s exactly what happened to Californian father Kali Kanongata'a who made headlines earlier this week when it was reported that he had live streamed his partner giving birth.

Right around the world, more than 120,000 times people have now watched his partner Sarah Dome give birth to their little boy, Ngangatulelei HeKelesi. They watched each groan and push they urged her on, they "liked" this incredible moment in her life time and time again.

She went viral.

In a time of social media, some said it was peak oversharing. That it was a private moment.

“The internet has been hard at work making profound video content like watermelon crushing and newspaper eating,” journalist Renata Sellitti wrote in Esquire magazine.

“But it's fair to say we've officially hit max web oversharing mode and should slowly back away from the ledge… It's still crossing the line to show footage of her knees up around her head to the Facebook world at large.”

Others said it was beautiful.

“It used to be that the birth of a child was a community event and all were involved and the children were not sheltered from it, but learned from the experience,” said one man.

But it now turns out that the oversharing part wasn’t actually intentional and that new mum Sara didn’t even know the birth was being broadcast.

Kanongata'a, 36, told People that he only realised the video was being shared with the world when his cousin from Tonga commented "Keep pushing" and he then saw the viewer count.

"I thought it was just going to my family and friends!"

The Californian dad says he had only initially wanted his family in Tonga to be a part of the experience but once he realised he decide to keep going.

Kanongata'a said that "for a second” he hesitated before leaving it for all to see.

"There's a lot of negative stuff on Facebook and so I thought this would be positive.

"I figured as long as I kept it PG – this is a birth – it's something to be happy about."

His partner Sarah Dome has admitted that she never knew he was recording, as she was you know too busy giving birth.

But said later it was “pretty cool”.

"I wanted our baby to remember it,” Kanongata'a, also known as Fakamalo Kihe Eiki, told CBC News. “It's something for him to remember when he grows up.

"There is nothing to hide about having a kid, it's a blessing and just to share it with people, I think it's just an amazing thing."

Kanongata'a told People that he and his partner see it as a positive.

"I know some people are mad that it's not private, but I'm from the island [of Tonga], and years ago, we would have water births in public. I wasn't too worried about hiding anything because our culture has done this for thousands of years."

Usually not by accident though.
