Honestly, it feels like just yesterday we were watching Kourtney Kardashian literally pull her own baby out on national television. Fast forward to early 2026, and that "baby" is basically a full-blown teenager navigating middle school. Time is weird. If you've been keeping up with the Kardashians since the E! days, the math probably doesn't quite add up in your head.
The family has changed a lot. We’ve gone from the Scott Disick era to the Travis Barker "Kravis" era, and the household is now a chaotic, beautiful blend of ages. If you are trying to figure out how old are kourtney kardashian's kids right now, you aren't alone—the ages range from toddlers in diapers to teenagers who are officially taller than their mom.
The Original Trio: Mason, Penelope, and Reign
Most of us still associate Kourtney’s kids with Scott Disick. They had three children together before their final split in 2015, and those three have grown up entirely in the public eye.
Mason Dash Disick: The 16-Year-Old Trailblazer
Mason is the one who started it all. Born on December 14, 2009, Mason is 16 years old.
He’s arguably the most private of the bunch these days. While his younger siblings are all over TikTok, Mason has spent the last couple of years staying mostly off the grid. It’s kind of a vibe. He’s a sophomore in high school now, and from the rare photos we see, he’s basically a mini-Scott with a streetwear obsession. He celebrated his Bar Mitzvah a few years back, which was a huge moment for the family, and since then, he’s been living that low-key teen life.

Penelope Scotland Disick: The 13-Year-Old Fashion Icon
Then we have "P." Penelope was born on July 8, 2012, making her 13 years old.
She officially entered her teenage years last summer, and you can really see it. She’s famously become Kourtney’s "mini-me," often seen rocking vintage band tees or showing off her surprisingly sophisticated skincare routine on social media. People have been freaking out lately because, at 13, she is already appearing to tower over Kourtney, who is famously the shortest of the sisters at 5'0". Penelope is definitely the creative soul of the family, often leading the charge on those viral TikTok dances.
Reign Aston Disick: The 11-Year-Old Wildcard
Reign is the youngest of the Disick siblings, and he’s currently 11 years old.
He was born on December 14, 2014—yes, he shares the exact same birthday as his big brother Mason. Talk about efficient planning. Reign has always been the funniest one to watch because he truly does not care about the cameras. He’s the kid who will make a face at a paparazzi or shave his head into a mohawk just because he feels like it. He’s at that age where he’s still a "kid" but definitely starting to get that signature Disick attitude that Scott is known for.

The Newest Addition: Rocky Thirteen Barker
After years of Kourtney being "done" with having kids, she and Travis Barker welcomed their first child together in late 2023. This changed the family dynamic in the best way possible.
Rocky Thirteen Barker: The 2-Year-Old Miracle
Rocky was born on November 1, 2023. As of January 2026, he is 2 years old.
His birth was a huge deal for the couple, especially after Kourtney was so open about her difficult IVF journey and the emergency fetal surgery she had to undergo. Rocky is still a toddler, so he’s not doing the red carpet thing just yet, but Kourtney occasionally shares glimpses of him on Instagram. He’s basically the baby of the entire Kardashian-Jenner-Barker empire right now, and the older kids seem completely obsessed with him.
The Barker Step-Siblings
You can’t really talk about Kourtney’s kids without mentioning her step-kids. The Barker side of the family is much older. Landon Barker is 22, Alabama Barker is 20, and Atiana De La Hoya is 26.

It’s a massive gap. You’ve got a 26-year-old and a 2-year-old under the same family umbrella. That makes for some pretty interesting holiday dinners. Kourtney has talked a lot about the "blending" process, noting that it took some time for everyone to find their place, but they seem to have settled into a rhythm where the older kids act like mentors to the younger ones.
Why Everyone Is Still Obsessed With Their Ages
There is a reason why people keep searching for how old are kourtney kardashian's kids. It’s because their ages mark the timeline of our own lives. If you remember watching Mason’s birth on TV, you’re likely realizing that you’ve also aged about 16 years since then. It’s a bit of a reality check for the audience.
Also, the Kardashians are the masters of the "rebrand." As each kid hits a new age bracket, their public persona changes. Mason went from being the cute toddler to the "cool" teen. Penelope went from the quiet daughter to the Gen-Alpha trendsetter.
Quick Reference: Kourtney Kardashian's Kids Ages (Jan 2026)
- Mason Disick: 16 (Born Dec 2009)
- Penelope Disick: 13 (Born July 2012)
- Reign Disick: 11 (Born Dec 2014)
- Rocky Thirteen Barker: 2 (Born Nov 2023)
What To Keep An Eye On
As 2026 progresses, expect to see Mason potentially hitting more milestones—like driving or looking at colleges (which feels insane). Penelope is also deep into her "teen" era, so her influence on TikTok and lifestyle trends is only going to grow. Kourtney has been very vocal about "slow living" and attachment parenting, so while the kids are famous, she tries to keep their daily lives somewhat grounded—or as grounded as you can be when your aunt is Kim Kardashian.
If you are trying to keep up with the specific dates for their birthdays, just remember that December is the "power month" for this family. Between Mason and Reign sharing the 14th and Rocky being a November baby, the end of the year is basically just one long party at the Barker-Kardashian house.
To stay updated on the kids' latest milestones, you should follow Kourtney’s lifestyle brand, Poosh, where she often shares her "non-toxic" parenting tips, or keep an eye on the family's Hulu series, which continues to document their transition into this new blended life.
