Kim Kardashian is wishing her eldest kid a happy birthday.
In addition to North, Kardashian and her ex-husband Kanye West also share daughter Chicago, 4, as well as two sons Saint, 6, and Psalm, 3.
"Happy Birthday my baby, my bestie, my everything," Kardashian penned the post alongside a carousel of adorable mother-daughter photos from over the years.
"There’s no one like you! The most honest, creative, silly girl with the best heart," she continued. "I just love being your mom, so thank you for being on this journey with me. I love you til [infinity]."
Kardashian's tribute to her daughter was quickly met with praise for being "such an amazing mom" and birthday wishes from fans.
"They grow up so fast!" one Instagram user commented on the photos. "North is so lucky to have such an amazing mom. This message was so pure and sweet and real."
"So sweet," another fan added.
"Cutest mother-daughter duo. Love to see it! Happy birthday, Northie! I can't believe how fast she's growing up. Where does the time go?" someone else wrote.
"She's the best thing you've ever given us!" another person chimed in.
"She is so lucky to have a mom like you," commented another.
In April, Kardashian revealed in an interview on "The Ellen Degeneres Show" that North has already started taking after her father, after she styled her and her other three children's family photoshoot for Vogue's March issue.
She explained that they were originally "all going to wear black," but North weighed in, calling the monochrome concept "boring."
"'I can't believe this is what we're gonna wear. I'm gonna dress everyone,' and she went in everyone's closet, picked it all out," Kardashian recalled.
