Hero gran delivers baby

A Sydney family is settling down after an amazing home birth that involved a mother, grandmother, and mother-in-law.

The frantic all-in effort was orchestrated by a trainee ambulance operator, with all the drama captured on a Triple-Zero recording.

Still stunned by the experience, Caroline Moore, held her baby and met the 27-year-old trainee who helped deliver him.

"It was great to have you on the phone. I don’t think we could have done it without you on the phone," she said.

Caroline was at home when the contractions began.

"I'm going to help deliver the baby okay,” Triple-0 operator. “Oh my god okay,” Caroline said. “We're going to do this and I'm going to do this with you okay?”

Caroline's mother-in-law called triple-zero while her own mum played midwife.

“The baby's coming, oh my god!” “Is she pushing or straining?” “No she's not pushing she's just having contractions.”

A very calm Jarrod Furness gave instructions from the call centre, telling her to take deep breaths.

"You make them believe they can do it, you tell them they can do it and they do," Furness said.
