There’s nothing sweeter than sibling love! Kim Kardashian took to Instagram on Monday, December 16, to show off how much her firstborn, North West, and newborn, Psalm West, adore each other in a new photo.

The 39-year-old simply captioned the sweet snap of her two kids with a red heart. In the pic, North is hugging her little bro, who is lying next to her. Cue the awws!

By the looks of it, North has been adjusting super well to being a big sister — especially since her parents Kim and Kanye West welcomed Psalm in May. It turns out, making sure North transitioned well to having another sibling was a priority for Kim.

“North always wants to be center of attention, which is why Kim’s making a huge effort to ensure her eldest doesn’t feel left out, especially now there’s four of them competing for her attention!” a source exclusively told Life & Style in May.

“She’ll let North pick out onesies and other cute baby clothes for Psalm to wear so that she feels involved, and has organized a no-expense-spared birthday party for her next month,” the insider divulged at the time. “So far there haven’t been any jealousy issues, North adores Psalm and treats him like a little doll.” We can totally see that!

In addition to having Psalm, Chicago and Saint as siblings, North is also pretty close to her cousin Penelope Disick. So close, in fact, that she considers Kourtney Kardashian and Scott Disick‘s little girl as her own sis.

“North and Penelope call each other sisters, that’s how close they are,” another insider exclusively revealed to Life & Style in June.

The source continued, “They want to do everything together. It’s hard to take them anywhere separately. They call each other on the phone, they beg for playdates most days and they’ll have sleepovers on the weekend.” We love how tight-knit this family is — goals!
