Kim Kardashian West fawned over her daughters Chicago, 13 months, and North, 5½, in a Sunday photo posted to her Instagram account, where the siblings spent some sweet time together.

North — whose dark hair hangs loose in gorgeous curls — is barefoot and dressed in a pink nightgown covered in a lips pattern as she reaches out toward her little sister, who sits on the stairs next to North while wearing an adorable star-patterned footie pajama set.

“My girls 💕,” the Keeping Up with the Kardashians star, 38, wrote in the snap’s caption.

Chicago has taken after her big sister in a multitude of ways — including musically! — since she joined the KKW Beauty guru and husband Kanye West‘s family in January 2018.

In a sweet clip Kardashian West shared to Twitter earlier this month, North was shown jamming out while her dad led their new “Sunday Service” gospel session.

And last month, Chicago could be seen enjoying the uplifting music all around her, dancing around in clips the reality star shared to social media. In one video, the tiny tot moved her arms around while she grooved to the music, while in another, she had a big smile on her face as she ran toward her mother.

In yet another clip, the spouses’ younger daughter could be heard off-camera adorably saying “Dada” over and over as she watched West, 41, lead the choir.

North seems to have come quite a ways from her “only child” mindset as her parents prepare to welcome their fourth child, a baby boy, via surrogate.

In October, Kardashian West revealed on Ashley Graham‘s podcast Pretty Big Deal that her oldest had a little bit of animosity toward her younger siblings: Chicago and brother Saint, 3.

After recalling some favorite family moments on KUWTK, the mother of three mused to the supermodel, 30, that she wasn’t sure North would feel the same way when she got older. “North acts like an only child at all times. I think she’s a little confused,” Kardashian West said. “She’s beyond jealousy now. She’s just like, ‘It’s my world.’ “

“She said to me the other day, ‘Mom … we just need to have another baby brother so that Saint can just leave me alone … so the girls can be on this side of the house and the boys can be on that side of the house,’ ” she added.
