Kim Kardashian [1] can add a new position to her résumé: babysitter. After Kourtney Kardashian gave birth [2] to her and Scott Disick's third child on Sunday, Kim treated the couple's children Mason and Penelope Disick to a Disney on Ice show in LA. The reality star brought her daughter, North West, and a group of girlfriends along for the fun. At one point, Kim took adorable pictures of the kids, including makeup artist Joyce Bonelli's son, Zeppelin Bonelli, as they waited patiently in a garage. "She's ready!" Kim captioned a snap showing North holding a large Chanel bag that matched her black ensemble, which is similar (albeit more casual) to the look she debuted in November [3]. In another picture, Kim smiled behind birthday boy Mason as the aunt and her nephew chewed on straws. "Happy Birthday to the lego master Mason!!! You are so big I can't take it! You are my everything!!!!! I love you so much!!!!" she wrote. Read on to see the group's new pictures, and prepare for a cuteness overload when you scroll through North's sweetest snaps [4].

Brittny Gastineau, Lisa Gastineau, Ciara, and Joyce Bonelli joined Kim and the kids.
