Monday marks a v. special day on the Kardashian squad's (and high-key basically all of our) calendars.
If you weren't already in the know, it's little, baby munchkin Saint West's birthday!
Bring on the major birthday loving fit for an adorable, little king!
I can't believe how quickly time flies! Watching my little Saint grow this past year has been amazing. He's seriously such an angel and could not be more adorable. What a light he's been for our family!
She accompanied her post with a so-DANG-cute photo of Saint putting on a ginormous smile in his stroller in addition to another picture of Kim holding him.
Kendall made a small photo collage of baby Saint along with posting a message.
Saint, I can't believe it's been a year since you came into our lives! You're the sweetest addition to the fam. Even though you're still so young, you already have the most happy and amazing personality. I love you!
Of course, OG momager Kris Jenner joined in on the happy birthdays with an Instagram post dedicated to the little man of the hour.
Just LOOK at the cuteness, and try not to smile uncontrollably.
Kourtney Kardashian also took to Instagram to spread the birthday love to her nephew.
An extremely special message appeared on Kim Kardashian West's website on Monday.
Her close friend Jonathan Cheban is in charge of posting to her site this week, and he surely did a great job in honor of Saint's birthday.
Two never-before-seen photos of Kim spending cuddle time with Saint were uploaded, and they are so adorable it hurts.
I can't believe today is Saint's first birthday! One thing people may not know about me is that I'm obsessed with babies, LOL. In honor of his birthday, I convinced Kim to let me share some never-before-seen pics! Happy birthday, Saint!
HBD, little Saint West — I hope your day is filled with so much love and joy.
