Kourtney Kardashian’s Kids Will Never Stop Being Adorable, and We’re Ready for a Spin-Off

Anyone who’s ever seen an episode of Keeping Up With the Kardashians knows that when Kim and Kourtney Kardashian‘s kids make an appearance, it’s hard to concentrate on anything else! Of course, we’ll always have a special place in our hearts for Mason Disick — Kris Jenner‘s first grandbaby and perennial Kourtney and Kim Take New York scene-stealer — but we’ve also grown to love Kourt’s other children, Penelope and Reign, whom she shares with ex-boyfriend Scott Disick. Get to know more about the adorable tots below!

Mason Dash Disick: Age 8

Though Mason often appeared on KUWTK (and its spin-offs) in his early years, since he began school, we’ve seen less and less of him on camera. Born on Dec. 14, 2009, Mason was famously pulled out by Kourt during his delivery — a moment that was captured for the E! reality show.

As for his unique name? When the brunette beauty first found out she was expecting a baby, she wasn’t technically dating Scott at the time, but the pair reconnected over the pregnancy. In an interview with Life & Style back in 2010, the parents explained how they came up with the name Mason Dash.

“The first time I started looking at baby names, Mason was the only one I liked,” Kourtney admitted. “It was the only one that stuck with me. Right before he was born, I told my aunt we were thinking about going with that for a name. She told me that Mason means the same thing in English that Kardashian means in Armenian — stone worker. Another aunt told me my great uncle used to use the name Mason when he made dinner reservations, because Kardashian was too long. When I heard that, I thought, ‘Oh my god, it’s meant to be.'”

And, contrary to popular belief, his middle name is not in honor of the famous sisters’ boutique. (If that were the case, she would’ve had to name her daughter after her children’s store, Smooch!) “Dash is not for my clothing store, as some people have suggested online. That would be stupid,” Kourtney said. “Dash is short for Kardashian, and it was my father’s nickname.”

Penelope Scotland Disick: Age 5

Kourtney had Penelope on July 8, 2012, and her birth was documented for the seventh season of KUWTK. When Mason met his sibling for the first time, his mama said, “Her name is Penelope,” to which the then two-year-old adorably responded, “No, her name is sister.”

At the time, momager Kris revealed to E! News how Kourt and Scott came up with the moniker. She revealed that the couple simply thought both names were cute and Kourtney’s grandma, MJ, was actually the one to suggest Scotland — an ode to her dad’s first name.

These days, P has a super adorable friendship with her cousin, North West! The duo — who are less than a year apart — often share milestones together. Most recently, the Kourt and Kim continued their tradition of having joint birthday parties for their daughters and threw an adorable Moana-themed bash! There were a ton of super fun activities for the kids, including a petting zoo, a tropical-themed bounce house, and party characters dressed up as the film’s stars Moana and Maui. Uh, where was our invite?!

Reign Aston Disick: Age 3

As for Reign Aston — who shares a b-day with older brother Mason (Dec. 14) — Kourtney almost used his regal name for her other kids. “I actually had the name on our list with Mason,” the 38-year-old told People magazine. “Then with Penelope, I had it on the list, but spelled R-A-I-N.” Third time’s the charm, it seems. “Once I found out I was having a boy, we just changed the spelling again,” she explained.

Sadly, Mason, Penelope, and Reign’s parents are no longer together. After nine years of dating, Kourtney and Scott are not together after officially calling it quits in July 2015 — just six months after the birth of their second son. Scott entered rehab shortly after for drug and alcohol abuse. On an episode of KUWTK, he admitted to the Kardashian clan, “It’s been a really hard time going from, like, having all of you guys, to having nobody… I f–ked up. I made the worst decision I could have ever made in my life.”

Though he pined after Kourtney for more than a year, the 34-year-old moved on in 2017 with 19-year-old Sofia Richie — daughter of music icon Lionel Richie. Needless to say, the pair’s age difference has the singer spooked. “C’mon, she’s 19,” he previously told Life & Style. “She’s going to go take the turn and get through it and come out the other side… It will course itself.”

That being said, Sofia has already met Scott’s kids. When Kourtney and Scott split up, she set a rule. “She told him he had to be in a relationship with someone for at least six months before letting her near the kids,” an insider exclusively dished to Life & Style. Scott finally reached that milestone with Sofia, “so Kourtney gave Sofia her blessing to meet the kids.” First, though, Kourt “insisted on a one-on-one meeting,” the insider continued. “She needed to ensure Sofia is responsible enough to play stepmom — and Sofia passed the test!”
