Kim Kardashian and Kanye West's children are growing up before our eyes! With the kids back in school, the 43-year-old mama of four shared a group photo of her mini-mes before they headed to class, and fans were shocked at how big they all look—especially North West. In the first slide, Kim smiled for a selfie with North, 11, Saint, 8, Chicago, 6, and Psalm, 5. In the second, the kids posed together, showing off their personal styles.

Saint, who recently started a YouTube account after signing an exclusive contract with his mom , decided to bleach his hair for the new school year. North looked beautiful with long flowing braids, perfectly shaped eyebrows, a mouth full of braces, a fresh manicure, and a wrist full of bracelets. "Wait that’s Northie??????" Kim's friend FoodGod commented in disbelief.

"Kimberly how is everyone so grown upppp" celebrity hairstylist Jen Atkin added. Khloé Kardashian shares adorable photo of her son Tatum; 'Mommy's boy' Kendall Jenner says Kylie’s daughter Stormi has the biggest crush on Devin Booker Khloé Kardashian says Saint West and Tatum have an "unexplainable connection" North and Chicago, who have both shot up in height, must be attending the same school since they were both sporting the same adorable blue uniform. Saint was also in the same-colored polo, so he might be enrolled there as well.

Little Psalm wore a red polo with khaki shorts, which also looked like a uniform. For their footwear, they all chose Nikes, rocking matching.
