Linda Campbell has loved her work delivering babies so much that it has taken more than 50 years for her to retire.

The 73-year-old ventured into midwifery in 1971 while training as a nurse at the Lyell McEwin Hospital in Adelaide’s northern suburbs.

Ms Campbell has been at the site ever since and has delivered generations into the world.

“When you’ve been here as long as me, you’ve birthed your babies’ babies, which is very special,” she said.

“I live locally too, so I meet a lot of the women that I’ve cared for out and about.”

That ongoing connection is important to Ms Campbell.

“Women remember their midwives,” she said.

“Women outside … come up to me and say, ‘Remember me? You birthed my baby who’s now 39,’ and it’s lovely.

“There was a woman I met last week. I’d been at her birth 40-odd years ago and now she was going to be the grandmother. So that was three generations.”

Now just days before her 74th birthday, Ms Campbell is hanging up her scrubs.

Birth notices and thank-you letters mounted on the maternity ward walls mark the thousands of babies Ms Campbell has helped bring into the world.

“Every birth is different, and every birth is special,” she said.

“I’ll be sad to leave. As you can see I’m well past retirement age, but I’ve really enjoyed it.”

With more than half a century of experience, Ms Campbell has served as a nurse unit manager and a mentor.

“I think it’s something to say about the unit that most of our midwives have birthed their babies in this unit,” she said.

“They trust you to look after them when they’re birthing.”

Lyn Bastian, who has worked with Ms Campbell for 13 years, described her colleague as “caring” and “compassionate”, and as a “dynamo” who is “so dedicated to midwifery, midwifery services [and] maternity care for the women and families of the north”.

“When I started here in my role, I had no idea what I was doing but she just took me under her wing,” Ms Bastian said.

“We all need mentors.”

Asked whether she could see herself being in the profession for the same amount of time, Ms Bastian expressed scepticism.

“I don’t think so. I’d love to but I doubt [it],” she chuckled.

“To work 57 years full-time, up until [Thursday] is pretty incredible. It’s just amazing.”

Ms Campbell has seen her community, and its needs, grow.

“When I first started, the Lyell McEwin was a community hospital. It was very small,” she said.

“It’s grown massively over the years. The need is great, especially in the north in our demographic area.

“We’re the second busiest [maternity ward] in the state following Women’s and Children’s.”

Thursday will mark Ms Campbell’s last shift, and if all goes to plan she will be delivering a baby as a send-off.

“I’ve helped train a lot of midwives,” she said.

“I’m their mother, their grandmother, and anything else in between.

“If I had a time machine, I’d do it all again.”
