Someone’s got serious big sister vibes! Kourtney Kardashian posted a new photo of her daughter, Penelope Disick, hanging out with her cousin Chicago West on October 24 — and she dished about how much the 6-year-old wants a little sis in her life. Considering she’s already got two brothers, we don’t blame her for wanting to expand the brood!

“Heart explosion,” the 40-year-old mama captioned the sweetest photo of P holding Chi during the recent Armenian trip Kourt took with sister Kim Kardashian and her children. Though North West, Saint West, Psalm West, Reign Disick and Mason Disick were all in attendance for the baptismal venture on October 7, Kim’s hubby Kanye West was MIA for the special moment.

Younger sis Khloé Kardashian made sure to show love on the post, writing, “Explodes 😍😍😍😍.” Her BFF Khadijah Haqq also commented, unable to help herself from sharing her observations on the sweet pic. “P loves babies 😍,” the 36-year-old wrote. The KUWTK star certainly had a response — and TBH, we’re totally on Penelope’s side with this one.

“I get baby sister requests daily,” Kourtney revealed in her reply. Maybe one of these days, Scott Disick and the brunette beauty will find their way back to each other and give P what she’s always wanted … and that’s a big maybe. But here’s to hoping! (Yes, we’re ~Scourtney~ shippers as much as we’re Scott and Sofia Richie shippers. Deal with it.)

It’s no surprise to see P latching onto Chicago in lieu of her own little sis. In fact, the cousins seem to be hanging out quite a lot lately — and might even rival the bond between cousins Dream Kardashian and True Thompson. Penelope was spotted giving the 21-month-old the piggyback ride of her life recently at Kim’s sweet 39th birthday dinner party and it was obviously adorbs.

Honestly, we think the little girl just really gravitates toward the big sister role in general, even though she’s dying for another girl in the mix. Kourt recently shared videos of her helping her little bro, Reign, on the monkey bars, as well as carrying him around during their trip to Portifino back in July.

We stan sister love, y’all!
