PARENTS say they have beaten odds of 30 million to one after their newborn twins were born on the same day as their nine year-old twins.

Zoe, 38, and Ben Sullivan, 42, are astounded at the coincidence at higher odds than winning the lottery.

Mother-of-nine Zoe, of Lossiemouth, Moray, gave birth to identical twins Leah and Erin, now one, 10 weeks early – meaning they were born on non-identical twins’ Charlotte and Isabelle’s eighth birthday.

Mrs Sullivan said one twin stopped growing in the womb, so she was induced 10 weeks early.

It means all four girls celebrated their birthdays on January 25.

She said: “Our family isn’t one in a million. It’s one in 30 million.

“Now all our kids want babies on their birthdays.”

Leah and Erin were meant to arrive last April but were set to be delivered in March as they were twins and would not reach a full term.

Mrs Sullivan added: “I went in on January 23 because I was experiencing complications. Erin wasn’t growing in the womb and doctors were concerned so I decided to be induced early.

“By coincidence, they were then born two days later on Charlotte and Isabelle’s birthday.”

Leah was born weighing 3lbs 4oz and Erin 2lbs 6oz at Raigmore Hospital in Inverness.

Erin had complications and was rushed to Aberdeen Royal Infirmary with sepsis.

She added: “It was pretty stressful. We had Leah in Inverness and Erin in Aberdeen – 87 miles away from each other – as well as seven children at home.”

Leah was allowed out of hospital at six weeks and Erin got the all clear at ten weeks.

Zoe and dad Ben, an RAF engineer, are parents to Elizabeth, 11, Olivia, 10, Charlotte and Isabelle, both nine, Noah, seven, Evangeline, five, Tobias, four, Lean and Erin, one, with one on the way.

Speaking of the special day on the 25th, Ben said: “It was lovely to celebrate the day after the stress of Erin and Leah’s birth.

“We have realised that we are going to have to budget for the 25th as it is an expensive day now with four birthdays!

“We have to budget and put money away every month.”
