For parents raising their kids in the age of social media, a decision must be made about how they much screen time they allow their kids each day.
With plenty of evidence that growing up on social media can be detrimental to mental health of kids and teens, lots of parents worry about how often their children spend online.
Whereas some parents take a more relaxed approach, others control their kids' screen time and allow them to only access social media platforms for an hour or so each day.
But one mum in the US state of Minnesota took a unique approach to the issue of her son and social media, People magazine reports.

Six years ago, Lorna Klefsaas offered her then 12-year-old son Sivert a deal - stay off social media until your 18th birthday and I'll give you $1,800 (£1340).
She called it the "18 for 18 Challenge" - and on 19 February when Sivert turned 18, he received his cash gift.
Speaking to US news channel KARE 11, Sivert said he "didn't really have that great a concept of money" at the time, but added he bit his mum's hand off to accept the deal.
Although Lorna recognised she was asking her son to give up a lot, she said she had no doubt he'd complete the task.
She told the news channel she as "proud" of her son, who struggled with the tall order at times, but always stuck to his promise.
Lorna came up with the idea after watching her older daughter struggle with growing up on social media as a teenager.
"She got so obsessed with keeping up her Snapchat streaks that really it was affecting her mood. It was affecting her friendships," she said.
As an "intervention," Lorna decided to take her daughter off social media which left the teen "really upset."
But after seeing three weeks later that her daughter was relieved and grateful to not be on her phone all the time, Lorna decided she'd adopt the same tactic with her younger son.
When Lorna first sat down to offer the deal to her son, she thinks he was a little too young to be fully caught up in social media - which they believe made it easier for him to stick to it.
She noted she never felt the need to check up on her son, saying he was "competitive" and knew he'd stick with it to prove a point.
After receiving his reward on his 18th birthday just a few days ago, Sivert told CNN: "I wouldn't say there was ever a time where I thought I was about to break."
He added his friends always kept him updated with anything he needed to know.
But now he's finally allowed to use social media, he's created his first ever Instagram account.
While he's getting to grips with how to use the apps, he admitted there's a bit of a "learning curve" to it all.
He said: "It's hilarious. I feel like I'm like 80."
Lorna noted that, although the family is not against social media, they want their children to use it healthily.
She said: "It's about not letting yourself get weighed down by it, or addicted to it, or affected by things that people post."
