It was anything but a textbook birth, and ultimately ended in tragedy, but even so it inspired Kate to devote her life to helping families through the incredible ups and heartbreaking lows of pregnancy.
The inspirational moment happened when as a trainee nurse almost 40 years ago she attended a routine birth, only for the unimaginable to happen after it was discovered that the baby's head had failed to form properly in the womb.
"Everyone seemed to take an inaudible breath waiting to see what would happen next," Kate says, explaining that the midwife continued to deliver the baby, knowing the child couldn't survive for long.
"We wrapped the baby in a blanket and placed it on the mother's chest allowing them to bond before later the child passed away. I was so inspired by that midwife I left the room determined to do more for complicated births."
Since that day Kate, 63, has dedicated her life to helping thousands of families navigate high risk pregnancies and health complications through birth and beyond – when joy sometimes turns to tragedy.
"We have a beautiful photo wall of babies we've helped," she says.
"When a new family are told their baby has a problem, there's probably a baby on the wall that has it too and has survived. It sparks hope."
And it's clear the incredible work Kate has done at the Department Maternal Fetal Medicine has made a lasting impact on those who receive her care, with past patients often returning to Sydney's Royal Hospital for Women to thank her.
"Each baby has a place in my heart," she says, explaining that she keeps a box of cards and messages from grateful patients to lift her spirits on tough days.
"I never forget them. It's the reason I want to come back tomorrow, because you know you can make a difference."
The Royal Hospital for Women Foundation wants all Aussies to share in their Heart for Her campaign and post a story of love for their friend, mum, child, sister, auntie or grandma – and our heroic nurses with a photo of a love heart on your hand and the social tag #heartforher during June.
"Our doctors, nurses, midwives and hospital staff are showing their heart and raising their hands to say thanks, and we're calling on the community to join them through this campaign," urges campaign manager Elize Jennings.
