However, Charlie, who recently celebrated his first birthday, had other ideas.

Mrs Madden delivered him at the couple's Naringal East home with the help of her husband Luke and mother Jenny Hillman.

The trio was on Wednesday reunited with the triple zero operator who helped them though the stressful experience.

Mrs Madden said it was a great opportunity to meet Madeleine Craven, who spoke to Mrs Hillman and Mrs Madden and offered instructions to Mr Madden.

"I asked her straight away if she would like to hold Charlie and she got really teary," Mrs Madden said.

She said she was extremely grateful to Ms Craven, who was able to keep everyone calm.

"My waters broke at home and by the time we got sorted to get in the car, it was a bit late," Mrs Madden said.

She said her husband had the car running and was ready to go, but she told her mother she felt the urge to push.

"Luke was trying to get me into the car to go, which was still running when the ambulance arrived," Mrs Madden said.

"I said 'I feel like I need to push' and mum told me to go back inside."

Mrs Hillman called triple zero and 12 minutes later, Charlie was born.

It was a further 10 minutes until first responders arrived and Mr Madden was able to cut the umbilical chord.

Mrs Madden said she was extremely proud of her husband and mother, who managed to keep her calm.

"I'm just so grateful they were there," she said.

Mrs Madden said it never crossed her mind that she may not have enough time to get to the hospital after the lengthy labour she endured when having son Tom, 2.

"It could have happened when I was home by myself with Tom."

Mrs Madden said she had not felt any contractions or pains before her water broke.

The Mercy Regional College teacher was one of eight Victorian mothers who had the chance to meet the triple zero operator who helped deliver their babies on Wednesday.

Every year operators help deliver about 100 babies over the phone, Emergency Services Telecommunications Authority chief executive officer Marty Smyth said.
