Just a day following her first appearance in a four-minute livestream on her app and website, the mother of two took her newborn son for a trip to a Los Angeles building, which seemed to be a doctor's office, reported Ace Showbiz.
Kim and Saint were joined by Kanye West and the couple's first child North West.
The 35-year-old reality TV star held Nori while her husband was in charge of carrying Saint in the baby carrier.
Kim sported an all-black outfit topped with an oversize coat which concealed her post-baby body. She styled her long hair in braids and sucked a lollipop. Kanye, meanwhile, was clad in a black hoodie and matching boots.
She has since been holed up in mom Kris Jenner's Hidden Hills mansion.
