This mother of five has never been in labour for more than two hours - and she remarkably manages to beat her delivery record every time she gives birth.

Mary Gorgens, who has never been given much warning before she goes into labour, has continued her stretch of speedy deliveries giving birth to her latest child in just two minutes. 

Even though the 35-year-old from Sydney has earned herself a reputation of rapid-fire births, nothing could have prepared her for the latest delivery on January 30.  Ms Gorgens went to the toilet in the early hours of the morning after feeling a slight twinge but had to quickly 'waddle' back to the bedroom when she felt her son's head starting to come out. 

She woke her husband Simon who stumbled to the bathroom thinking he had some time.

When he came back, the 40-year-old found his wife on all fours and two minutes later he was holding his son Brody in his arms.

'I had no inkling, no feeling, no pain. He was two days early, I really wasn't expecting it that day,' Ms Gorgens told Daily Mail Australia. 

Luckily, the Gorgen family are used to these rapid-fire births.

When she gave birth to their first child Max in December 2008, Ms Gorgens made it to the hospital with just 12 minutes to spare. 

'One push and the head was out and one more and then his body came out. We got to the hospital at 10.22am and Max was born at 10.34am,' Ms Gorgens said.

The couple's second child Ava was born in 90 minutes in the car when the couple were on their way to the hospital. 

When it came to Sienna's birth in December 2011, the couple attempted the hospital dash again.

'Simon managed to stop on the median strip, he ran to my side and her head was already coming out,' Ms Gorgens said.

'He grabbed her and delivered her... then we rushed to the hospital again. Sienna only took 50 minutes.' 

But the couple's fourth child was considerably quicker and they didn't even made it to the car.

'Mila was born on our bedroom floor in 10 minutes,' Ms Gorgens said.

Ms Gorgens hasn't had pain relief in any of her five births because there hasn't been enough time.

'I don't have pains for hours on end beforehand. It's intense for a short amount of time. It's pretty crazy. I've had five go that way and they have all been quicker than the last.

'My friends joke that I could sneeze and a baby would pop out.'

The mother of five considers herself extremely lucky with some of her friends going through 40 hours labours. 

'I'm lucky because even though we weren't in hospital, at the end of the day they went smoothly and they were all healthy. 

'It's amazing what your body can do.'
