It’s a brother-sister thing. Kim Kardashian shared the most hilarious series of photos that showed North West making a sassy face at Saint, who gave it right back to her. In the mix was baby Psalm looking peaceful as ever on his big sister’s lap. The Keeping Up With the Kardashians starlet has been open in the past about their sibling rivalry, and it’s equal parts adorable and entertaining.

“It was going so good,” the 38-year-old jokingly captioned three photos on August 20. The first one showed the spunky 6-year-old looking calm while cradling the newborn, 3 months. Side note: We are swooning over how much Psalm looks like Chicago! Saint, 3, then struck a silly pose by throwing a peace sign up in the air in the second snap. The third picture shows the sibs ending the serene moment by making sassy faces at each other.

This was a very ~relatable~ moment to all the parents out there, and fans flooded the comments complimenting how gorgeous the reality starlet’s kiddos are. “North’s lashes!!! God bless your babies they’re beyond perfect,” one person gushed. Another user added, “Kim your children I cannot,” while someone else echoed, “Cuteness overload.” Of course, people couldn’t help but point out how funny their reactions were in the third photo. “They all have that Kanye face mastered down,” one comment read. Even Khloé Kardashian chimed in and wrote, “Omg that last pic is hysterical.”

While Kim and husband Kanye West certainly have their hands full, they love being a large family of six. “Kim and Kanye feel like their family is complete. Kim used her last embryo with Psalm, and four kids is enough for them to handle!” a source divulged exclusively to Life & Style about their future plans. Of course, never say never, but we think the Kardashian-West squad looks pretty solid.

We can’t wait to see more adorableness from Kim!
