Although the KKW Beauty mogul and husband Kanye West’s third child made her big social media debut in aunt Kylie Jenner’s video welcoming her daughter Stormi back in February, this is only the third time Kardashian West has shared a picture of Chicago.

Last week, the 37-year-old posted a series of sweet St. Patrick’s Day shots of the tiny tot wearing pink pajamas.

Morning cutie,” the reality star captioned one of the pics.

Chicago made her debut on Kardashian West’s Instagram Story in February, wearing — fittingly — a cub filter.

“Baby Chicago,” Kardashian West wrote alongside the image as she cradled her baby girl in her arms.

While attending the Create & Cultivate event in Los Angeles in February, Kardashian West explained to her best friend Allison Statter how she makes sure to include some phone-free quality time with her kids.

In addition to Chicago, Kardashian West and her husband are parents to Saint, 2, and daughter North, 4½.

“One of the rules I have about being present with my kids is I don’t have my phone when I’m with them. So, like story time at night, in the mornings getting ready, I just don’t have my phone,” she said.
