Mum’s shock as her baby weighs 6.3kg, twice the size of an average newborn

A mum has given birth to a baby boy who weighed in at 6.3kg – twice the average size of a newborn – and he went straight into clothes for a nine-month-old.

A mum gave birth to a massive 6.37kg baby who was so huge he went straight into clothes for a nine-month-old.

Parents Cary and Tim Patonai, of Arizona in the US, knew they were expecting an unusually big baby when doctors predicted he would weigh around 6.25kg when he was born.

But Finnley was 6.37kg when he was born – nearly double that of the average weight of a newborn.

Cary told Fox News: “He was so big plus I had almost double the amniotic fluid, so to say I had a big baby belly and that I was absolutely completely uncomfortable isn’t enough.”

At her last ultrasound, nurses told her Finnley appeared to weigh 5.89kg – but insisted he probably didn’t actually weigh that much.

Cary was scheduled to deliver the baby via C-section on October 5, but things got hurried along at her check-up the day before when her waters broke.

“My water broke on the scale as I was getting weighed, so my scheduled C-section got moved up a day,” she said.

She delivered at Banner Thunderbird Medical Center in Glendale, Arizona, and insisted she would “do it all over again” if she had to.

“Finnley was a little celebrity at the hospital. Nurses and doctors were non-stop talking about him. He is quite tall too at 23.75 inches (60cm),” Cary said.

“As soon as they pulled him out, they’re like, ‘Oh my gosh, that’s huge!’

“Everybody was freaking out, like, ‘I’ve never seen a baby that big, I can’t believe it.’ So perfect and round in every way. He’s definitely my squishy little honey bear.”

Banner Thunderbird Medical Center only carried nappies for newborns – but Finnley is already a size two, so they had to put in a special order for his size.

And the Patonais’ family had to rush out for baby clothes in size six to nine months.

Cary said: “Everything we had was entirely too small.”

Cary and Tim had already welcomed two boys – 10-year-old Devlen and two-year-old Everett – via C-section, each weighing 3.7kg and 5kg.

But both were small compared to little brother Finnley.

The average weight of a newborn is around 3.4kg but between 2.49kg and 4.5kg is considered normal.

Finnley had to spend eight days in the NICU before he went home.

“There was one point in the NICU that he was with one of four babies, and his weight was their three total all together, so we were laughing at that,” Cary said.

“He is such a good sweet baby. I am so grateful everything ended on such a great positive side.”
