Kourtney Kardashian is opening up about social media rules in her house and why she deleted her son Mason‘s secret Instagram account.

During a Q&A session with her friend Sarah Howard on Instagram Live on Wednesday, Kourtney shared that 10-year-old Mason — whom she shares with Scott Disick along with daughter Penelope, 7, and son Reign, 5 — didn’t ask his parents for permission before creating an account on the social media platform.

“I see a lot of comments about Mason’s Instagram being deleted,” the mother of three said.

“He didn’t ask us,” she said, adding that while he doesn’t have a smart phone, he does have an iPad and a computer for school.

“I did delete it because Scott and I just felt like he isn’t [old enough],” she continued. “He’s 10. I think there’s an age limit with Instagram, I think it’s 13.”

The Poosh founder added that she doesn’t want her kids to be exposed to the bullying that often accompanies social media.

“I think the thing that really worries me with kids is, people can be so mean,” she said, adding that it is “really easy to get consumed with it” as well.

Kourtney said that she and Scott “feel like it’s not the time” for Mason to join Instagram just yet.

“I made it private and then [Mason] turned it back to public without me knowing… so I just [deleted it],” she said. “It’s gone, it’s deleted.”

Kourtney has previously said that she wouldn’t call herself a “strict” mom, but that “I love to communicate with my kids, and I constantly check in and try to talk things through instead.”

In an E!-exclusive vlog from 2012, she said, “We just communicate, and I know that [Mason] may not always agree with my decision.”
