Expectant mums, look away now - these birth stories are not for the faint hearted.
A TikTok user has opened a huge can of 'oh my god' worms when they asked mums to share their stories of birthing big babies. And oh baby did they deliver.
As one mum replied - to claim biggest baby dibs, her second son weighed in at roughly 6.3kg.
"You wanna play the biggest baby? I got you. At 38 weeks and one day I had my second son via C-section with two doctors because he came in at a whopping 14Ibs, 0.6oz," the mum answered original poster Tawnee.
He was also close to 60 centimetres long.
"Yes, I gave birth to a toddler, who then spent 11 days in the NICU where clearly he was the biggest baby in there. The NICU did not even have diapers for him or clothes. They had to go up to pediatrics to get size three diapers. And he came home in clothing (for) six to nine months."
Her response drew plenty of comments, with one joking they'd 'never seen a colossal titan', while another said 'The baby drove her home from the hospital'.
'That ain't a baby, that's the Michelin man. Just playing, good on you mama,' another quipped.
The original video, but mum of three Tawnee also attracted many comments from mums sharing their own large babies - and from adults who had been big babies themselves.
"I don't have any children of my own, but I was 14Ibs, 2oz at birth," shared one, "My husband was born 15Ibs, 15oz," added another.
"I was 16Ibs, 4oz, 22 ½ inches tall. Biggest baby ever born in Riverside County, CA," one proud man wrote.
"My 15yo brother was 12.6IBs at birth. He still holds the record for biggest baby at the hospital he was born (my mum works there)," said one user.
In Australia, the biggest baby born is believed to be Stephen Lyttle, who was born at 16Ibs, 5oz - or 7.28kg, close to four kgs above the average Australia birth weight of roughly 3.3kg.
While according to the Guiness World Records, the largest known baby was born in Italy in 1955, weighing an unbelievable 22Ibs, 8oz - an eye watering 10.3kg.
