The blogger and her husband, Jonathan, have been sharing their lives on their YouTube channel – which now has over a million subscribers – for years.
The Saccone-Jolys took the stage at the PEOPLE and Entertainment Weekly panel at VidCon 2015 on Saturday, where Anna explained that her husband's skills in the editing room made letting the world watch her give birth an easy decision.
"I think because Jonathan is good at editing I didn't have any fears on that because it just felt like something natural. We've been vlogging every single day for the past five years so it would've been strange not to vlog it," the online reality star told fans.
Jonathan chimed in to let audience know that the infamous video was cut down for public consumption. "There's two versions of both birth videos," he said. "There's the version everyone has seen and there's the other version."
The Irish couple also revealed that one of the 2.7 million people who watched the 2012 video, titled "Lives Changed Forever," is one its stars: their daughter Emilia, 3.
"She's watched her own birth video, and I'm like, 'That's you!' And she's like, 'It's a baby,' and I'm like, "No that's you!' "

Two years later, the Saccone-Jolys filmed the birth of their son, Eduardo.
When asked if the parents think their children will ever resent the publicity, Jonathan joked, "They're going to hate us inevitably, so why not just have a good time?"
Anna, however answered more seriously, saying, "We're in control as their parents. We kind of try and think, 'Okay we're not going to show tantrums. We're not going to show things that they might be embarrassed about.' We're quite careful about that."
