The Murphy quadruplets, from Riverstick in Cork, celebrated their eighteenth birthday today surrounded by the medical staff who brought them into the world.
The Quads hit headlines when they were born, not only due to the fact they were quads but also because of the size of the medical team who delivered them.
45 staff looked after them and their mother in Erinville Maternity Hospital.
Shauna, Kellie, Amy and Katie celebrated today's milestone birthday by going to Cork University Maternity Hospital to meet some of the staff who delivered them on that day 18 years ago.
Many of the staff and nurses, including Professor John Higgins, Consultant Obstetrician and Gynaecologist, hadn't seen the quads since they were very small.
Patrick and Brenda, the girl's parents, also attended and were delighted to see the staff again because they treated them and their daughters so well.
The girls were born 13 weeks premature so it was all hands on deck for the staff who helped with the delivery.
The sisters were kept in hospital for a few weeks until they were strong enough to go home.
Now, they are studying for their Leaving Cert at Kinsale Community School, which many of the midwives, nurses and doctors could not get over.
Mother Brenda says it was surprising when she got the news that she was having four babies.
"Shocking," adds Patrick, the girl's Dad.
However, despite the challenges, they said it was very rewarding seeing their girls grow up and share milestones together.
The couple had a son called Cian who was only two years and three months when the girls arrived.
"It was hard to adjust because we were up and down to the hospital all the time, for up to ten weeks. Katie was the last one to come home. It was mayhem," says Brenda.
Professor Higgins said the day of the girl's birth was very dramatic.
"We only had 45 minutes and luckily we had a plan. All the staff were so switched on to the fact the mother was having four babies and having them very early. The babies needed to be looked after in a very careful and detailed way.
"One family can bring out the very best in all of us, and they certainly did."
The Murphy sisters said it was nice to meet the staff who helped deliver them.
"They were so important to us at the time," says Kellie.
The girls say they get a lot of attention because they are quads.
"It's just normal to us, people ask us to describe it but we don't know any different," says Kellie.
The girls are currently studying for their Leaving Cert.
While they study very different subjects in school, they do help each other with their common subjects.
Kellie helps with History and Amy helps the girls with Irish.
"That's her practicing her teaching already," says Shauna.
All of them want to stay in Cork for college, but they might move away after this.
"I want to study Education and Irish and another language in UCC," says Amy.
She plans to become a teacher and she is also the sporty one of the sisters, playing camogie.
Shauna says she wants to do an apprenticeship with a cybersecurity company, while Kellie wants to do Arts.
"Maybe English, Politics and History," she says.
Katie wants to be a dog groomer and has already been working as one for the past few years.
"I just love dogs. You have to be very patient with them."
The girls are all in the same friendship group and they are very close.
This doesn't stop them from fighting occasionally.
"But all siblings fight, it's not dramatic," says Amy.
They say the would like to live in Cork when they are older, but maybe not live together.
Amy and Shauna already share a room, Amy is very messy and Shauna is tidier. "I come home and see all of her stuff on the floor and I throw them onto her bed, but she just throws them on the ground again," says Shauna.
"I'm not that messy!" laughs Amy.
One thing is certain: the girls all have very different personalities but despite this, they are the best of friends and will continue to be so.
hem. We wish them the best of luck for the future.”
