Natashia gave birth naturally and only needed gas to ease the pain
In fact, he is one of the largest babies ever born in Australia.
Tipping the scales at a whopping 6kgs, or 13.11 pounds, Brian Liddle Jnr weighs twice as much as an average baby.
He was born at Mercy Hospital, in Melbourne, Australia on January 24, but even before his birth doctors knew he would be a bigger than average bundle of joy.
By the time mum-of-four Natashia Corrigan went for 36-week scan, her son was already a kilogram heavier than what her daughter weighed at birth. But just how big her baby would be after just an extra few weeks of growing shocked Natashia, who has been through childbirth three times before.
And all Natashia needed to get through the birth was gas.
Baby Brian is the heaviest baby ever born at Mercy Hospital and measures an astonishing 22 inches long.
Natashia said : “I dreamed of a little fat baby.
“I’ve always wanted a little fat baby and now I’ve got a big baby.”
She said hospital staff and her partner, Brian Liddle, helped get her through the record-breaking birth.
She added: “They kept me strong and calm when it seemed like chaos was happening around me.
“This is the first pregnancy I’ve got to experience with a natural labour, the longest I’ve ever been pregnant and I’ve got the fat little man that I wanted.”
Partner Brian said the birth was “a bit scary” but that it all worked out for the best.
According to the Guinness Book of World Records, the heaviest baby ever born weighed 23 pounds and 12 ounces – just under 11kgs.
The baby, born in Canada in 1879 to mother Anna Bates who had giantism, measured an huge 28 inches.
But the baby died 11 hours after birth.
The record for the heaviest baby born went to a baby boy born in Italy in 1955, who weighed 22 pounds and 8 ounces – an astonishing 10.2kgs.
