Mom Gives Birth To 13-Pound Baby Boy, Breaking Hospital Record And Hearts Online

Nashville, Tennessee — A new mom has captured hearts — and headlines — after giving birth to a 13-pound baby boy, setting a new record at TriStar Centennial Women’s Hospital and sparking waves of online reactions filled with humor and amazement.

Shelby Martin, who shared her pregnancy journey on TikTok, delivered her son Cassian via C-section earlier this month. The baby weighed 12 pounds, 14 ounces (5.8 kg), making him the hospital’s biggest newborn in more than three years. Her viral post has drawn millions of views and thousands of comments from astonished followers reacting to Cassian’s size and the emotional story behind his birth.

A Viral Moment That Melted Hearts

In a now-viral TikTok video, Martin appears in her hospital gown proudly displaying her enormous baby bump. “When people talk about having a big baby, like I don’t know ball. But trust me… I know ball,” she joked in the caption, a line that resonated across social media and quickly amassed over 4.4 million likes.

The video then cuts to baby Cassian, fresh from delivery and surrounded by surprised nurses and doctors. Viewers couldn’t help but marvel at the sight, flooding the comments with playful disbelief. One user asked, “How many years was he in there?” while another quipped, “Did the baby have to come out of the sunroof?”

Hospital Staff Celebrate The Milestone Birth

The hospital confirmed Cassian’s delivery as one of the largest in its recent history, calling it a “beautiful reminder of resilience and love.” Following his birth, Cassian spent a brief period in the neonatal intensive care unit (NICU) to monitor his glucose levels and breathing, where he received IV fluids and oxygen.

Martin expressed her gratitude toward the medical team, saying, “The ladies that took the best care of me and helped me navigate C-section recovery as a first-time mama — I’ll never forget you. And thank you to the NICU team who loved on him when I couldn’t.”

Adding to the story’s sweetness, Cassian was born on Shelby’s own birthday, a moment she described as “the greatest gift.”

Big Babies Making Big Headlines Nationwide

Shelby and Cassian aren’t alone in their record-breaking spotlight. In Riverview, Florida, another mother, Daniella Hines, recently gave birth to her 13-pound, 15-ounce son Annan, while in Birmingham, Alabama, Pamela Mann welcomed a 13-pound, 4-ounce daughter, Paris Halo, earlier this year.

According to Stanford Children’s Health, the average newborn weight is around 7 pounds, making these babies nearly double the norm. Doctors say while larger births are uncommon, they’re often linked to genetics or gestational diabetes, and most babies born this big are perfectly healthy.

From Hospital Fame To Viral Stardom

What makes Martin’s story stand out is the combination of humor, gratitude, and relatability. Her willingness to share her experience publicly has turned Cassian into a miniature celebrity, with parents nationwide joining the conversation about motherhood, delivery challenges, and celebrating the beauty of big babies.

Martin’s candid approach — from joking about her “basketball-sized” belly to thanking her care team — has inspired an outpouring of love across social media. Cassian’s arrival, she says, is proof that sometimes the best surprises come in the biggest packages.
