Sibling love! Kourtney Kardashian shared the sweetest video of Penelope Disick asking Mason to help her out so she can carry Reign. “Once upon a time in Portofino,” the mom-of-three captioned the footage and a slew of Instagram photos from their luxe vacation to Italy. During their time in Europe, the Keeping Up With the Kardashians stars also met up with the rest of the famous family to celebrate Kylie Jenner‘s 22nd birthday during their trip. The Poosh founder isn’t shy about sharing adorable moments of her kiddos but this latest video is just too pure.

“Can someone put Reign on me?” the 7-year-old asked in the video posted on August 15. Big brother Mason, 9, stepped in to help lift their youngest sibling, 4. Reign seems unbothered by being forcibly stuck on his sister and said in the sweetest little voice, “Mas, you’re strong.” OMG, our baby fever is truly out of control with these kids.

Kourtney and her baby daddy, Scott Disick, seem to be having a blast raising their three children. Although they are no longer romantically involved — Scott is in a committed relationship with Sofia Richie — the exes are still extremely close and get along better than ever. They’ve worked hard for their amicable friendship and realized that their children come first.

“The truth is, my problems shouldn’t affect the kids,” the Talentless founder, 36, told Us Weekly on June 24. “Just because their mother and I couldn’t make it as a perfect, romantic couple shouldn’t have anything to do with the kids. They don’t deserve our mistakes, so we figured out a way. We still need to be as honest and as good to each other as if we were together. Let’s raise these children together and that’s it.”

The parents officially split in 2015 but never got too far away from each other. “We live a few miles apart and it’s simple,” Scott added.

We can always rely on the Disick family for our weekly dose of cuteness. Until next time!
