Cassian: Proud mum Shelby Martin’s newborn son a viral sensation after he breaks hospital weight record

There are big babies and then there is Cassian.

The newborn from the US has become a viral sensation after weighing in at a whopping 5.8kgs (12lb 14oz) at birth.

His proud mum, Shelby Martin, set the internet on fire after sharing a series of images of herself pregnant in a hospital gown and Cassian soon after he was born.

Alongside the post on TikTok that has been liked more than 4.2 million times, she wrote, “When people talk about having a big baby like idk ball. But trust me I know ball”.

Predictably, her followers are having some fun in the comment section.

With huge chubby cheeks, double chin and fat rolls on his arms and legs, Cassian broke hospital records when he arrived at Nashville’s TriStar Centennial Women’s Hospital in September.

He was the largest baby born there in the past three years, local news station 4WSMV reported.

The heaviest baby ever born, according to the Guinness Book of World Records, was a boy born in 1897 who weighed in at a whopping 9.98kg. Sadly, he was never named and died 11 hours after being born.

In a post on Facebook, TriStar Centennial wrote that Ms Martin had lost a baby the previous year.

“After loss comes light. Just one year after experiencing an unimaginable loss on her birthday, this mom welcomed the greatest gift-- Baby Cassian—who now shares the same birthday as her.

“Born at 12 pounds, 14 ounces, he is the largest newborn delivered at TriStar Centennial Women’s Hospital in the past 3 years, their story is a beautiful reminder of resilience and love.”

Responding to the post Ms Martin, who had a caesarean, thanked the hospital staff for their care.

“No question was too silly and I was never made to feel like a burden and I needed ice water 1,000 times.”

“Another huge thank you to the NICU team that cared for our big guy and loved on him when I couldn’t.

The comment section on Ms Martin’s TikTok post is filled with followers poking gentle fun at Cassian’s size.

One person asked, ”Did the baby have to come out of the sunroof????”

Another wrote, “Did you have to push or did he walk out?” while another chipped in with “How many years was he in there?”

NFL team the Detroit Lions even got in on the fun writing ”Where does he see himself playing on our (offensive) o-line??

There has been no explanation provided for why Cassian came out so large, but her followers have been speculating.

“The doctor looking at the husband...tf is this?” joked one.

Another chimed in with, “Sue the father you have no other option.”

Ms Martin moved to defend Cassian.

“Y’all are tearin my poor fat son up in these comments 😫,” she wrote.

And went on to write, “luv my baby jimbo”.
