North West should know that turning 5 years old comes with a lot of responsibility . . . well, according to Kim Kardashian [1]. On Friday, the mom-of-three took to social media to wish her first born child [2] a happy birthday with sweet messages about her "best friend" [3] and daughter. But if there's anything we know about Kim, it's that she loves to throw a little sass in whenever possible, and when it comes to parenting, it's far too relatable [4].
"Now that you're 5, don't you think it's the mature thing to try to be nice to your brother!?!" Kim wrote on Twitter [5] alongside a fabulously adorable photo of North in New York City the day before. Ha! Well, Kim, as a 26-year-old with a brother two years younger, that "mature" kindness should not be expected with age. Let's just hope when baby Chicago is a little bit older [6], she can mediate the fighting between her older siblings! Read on to see the hilarious birthday messages and all the funny (and reassuring) reactions on Twitter.
