As many parents will know, despite the bundle of joy that you have at the end of it, childbirth is rarely a glamorous and pleasant occasion. But do spare a thought for this Australian mom, who gave birth via cesarean-section to a baby girl weighing an astonishing 6kg (12lbs 9oz).

What's even more amazing is that baby Remi Frances Millar didn't even arrive at full term, with parents Emma and Daniel Millar welcoming their new daughter 38 weeks and two days into Emma's pregnancy at Wollongong Hospital, NSW.

To put that into context, the average weight for a newborn child born at 37-40 weeks in the US is between 5lbs 8oz and 8lbs 13oz, per KidsHealth. The average weight for a newborn baby in Australia is 7lbs 2oz (or 3.3kg). Just 1.2% of children born in Australia weigh more than 4.5kg.

Speaking to news outlet Illawarra Mercury, Emma, from Sydney, has described her daughter as a "mini sumo wrestler" due to her incredible size: "I did expect to have a larger baby as I had gestational diabetes but not this big.

"At 35 weeks an ultrasound revealed she was about 4kg but we didn't think she'd grow that much more."

Whatsmore, the couple's two other children - four-year-old son, Ace, and two-year-old girl, Willow - were also born larger-than-average, weighing 5.5kg and 3.8kg respectively.

Due to Emma's recovery from her c-section - required do to her waters breaking early - doctors have told her that she is unable to lift anything heavier than her six kilogram daughter. Emma is actually thankful for the c-section, revealing she "couldn't have handled" a natural birth with Remi.

Father Daniel said: "When I've walked around with her there's always a crowd of people - midwives, other new parents and visitors - around her, asking about her size because she's so much bigger than all the other newborns.

As a result of Remi's surprising size, the couple has been forced to buy new clothes for their huge bundle of joy, as the baby outfits they had already purchased were far too small.

Per the Sun, the heaviest baby on record was a boy weighing 10.2 kg (22.5lb), who born in Italy in September 1955. Mamma mia!
