And with good reason: She's completely adorable. Although little Nori is now a big sister to a newborn baby boy, that hasn't distracted us from the 2-year-old's enduring cuteness. The daughter of Kim Kardashian and Kanye West has captured our hearts with her charming smile and sassy curls from her very first snap, and we simply can't get enough. To celebrate North's official transition into big sister-dom, we're taking a look back at some of her sweetest photos on Instagram—ever. From dressing up with cousin Penelope in Frozen costumes to trying on aunt Khloé Kardashian's sunglasses and showing off her soccer skills, there are plenty of Nori 'grams to satisfy any fan. Be prepared for an overload of cute, cute, cute!
