Reality TV star Kourtney Kardashian and musician Travis Barker have expanded their blended family with the arrival of their first child together, a baby boy whose impending birth was joyfully announced amidst a Halloween-themed celebration and a worrisome medical ordeal.

Kardashian, 44, and Barker, 47, tied the knot last year and have been in the spotlight regarding their fertility journey, which culminated in a sex reveal party back in June. Barker shared a glimpse into their personal joys and challenges on the "One Life One Chance" podcast, expressing his anticipation for his newborn son.

This addition brings the couple's collective number of children to seven. Kardashian is a mother to three children with ex-partner Scott Disick-Mason, 13, Penelope, 11, and Reign, 8. Meanwhile, Barker brings to their family his two children, Landon, 20, Alabama, 17, and stepdaughter Atiana, 24, from his previous marriage to Shanna Moakler.

The journey towards their son's birth has been one of both celebration and concern. In a creative twist, the couple shared a Halloween post where they channeled characters from "Beetlejuice," cleverly captioning their costumed post, "I'm the ghost with the most, babe." The image featured Kardashian's growing baby bump accentuated by a vibrant red dress.

However, the path to motherhood this time around was fraught with hurdles for Kardashian, who has had relatively smooth pregnancies in the past. The Lemme founder faced what she described as a "medical emergency" necessitating urgent fetal surgery. Sharing the ordeal with her followers, Kardashian revealed her deep-seated fears and the newfound respect she has gained for mothers enduring high-risk pregnancies. "I have a whole new understanding and respect for the mamas who have had to fight for their babies while pregnant," she said, attributing her strength to her husband and her doctors.

The baby's name, Rocky Thirteen Barker, is a unique blend reflecting the family's distinctive naming tradition, with Barker joking about the newborn's anticipated energy and strength. The name has even earned the seal of approval from Barker's daughter, Alabama, who praised its originality and fit within the family's unconventional naming style. The couple originally announced the pregnancy during a Blink-182 concert, with Kardashian holding up a sign that proclaimed the news, echoing a memorable moment from the band's own music video. The announcement video, shared on Instagram, captured Barker's heartfelt surprise as he embraced his wife in the audience.

Fans and followers of the duo have been privy to their pregnancy journey, with Kardashian openly sharing updates and images. Yet, it was her candid share about the required urgent fetal surgery that underscored the gravity of their situation. Despite the scare, the couple expressed their gratitude, with Kardashian stating, "Walking out of the hospital with my baby boy in my tummy and safe was the truest blessing."

This new chapter in their lives marks a moment of joy and relief as they welcome their son, whose birth was humorously predicted to be on Halloween but arrived in the first week of November. The couple's happiness and resilience are an inspiration to many, highlighting the profound journey of bringing a new life into the world amidst trials and tribulations.
