Kourtney Kardashian Barker

Let’s begin with the eldest Kardashian child, Kourtney. Kourtney Mary Kardashian Barker was born on April 18th, 1979, making her the oldest child of the late Robert Kardashian Sr. and his former wife, Kris Jenner. The Poosh founder shares three children (Mason, Penelope, and Reign) with her former boyfriend, Scott Disick. While the two had a rocky relationship during their history, Kourtney and Scott have nothing but the very best love for their kids.

Mason Dash Disick is the oldest child, and his birthday is December 14th, 2009. His birth was a milestone for the Kardashian family, for not only is he the first grandchild, the first of the family’s new generation, but his birth was documented in the fourth season of The Kardashians-making reality TV authentic.

The Lemme founder pulled her son out in the delivery room for substance.

The young teen prefers to live out of the limelight, opting for his privacy. Now and then, a photo will surface online, but with Kourtney’s permission.

Penelope Scotland Disick is the second child and only daughter of Kourtney and Scott. Her birthday falls on July 8th, 2012. According to her mother, Penelope is her “dream daughter” and idolizes her. As the only girl, Penelope is a “mommy’s girl and daddy’s girl.”

Reign Aston Disick is the youngest child of Kourtney and Scott. He shares the same birthday as her older brother Mason but was born five years later in 2014. Like all young boys, Reign enjoys games, his iPhone, and hanging out with his large family.

Rocky Thirteen Barker is the latest addition to the famous family. He was born on November 3rd, 2023; after several years of trying to get pregnant by IVF, Kourtney and her husband, blink-182 drummer Travis Barker. Rocky shares the same birthday as his aunt, Kendall Jenner.

The happy new mommy-to-be has embraced every moment and shared many on Instagram.

Kourtney is also the stepmother of Travis’s three children-Alabama Louella Barker,17, Landon Barker, 19, and Atiana de la Hoya, all of whom Travis shares with his ex-wife Shanna Moakler.
