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.
Incredibly, this is the first time Natashia has ever experienced a natural birth – a thought that would make most mothers cringe given the size of baby Brian.
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.
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.
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.
