The chances of having three children with the same birthday were almost impossible. To be exact, they were an incredible 48,627,125 to one. But for Jennifer and Driss Allalai, having three children all born on the same date is very much a reality.
On October 7, Jennifer gave birth to their third child, Sami – on the birthday of his older brother, Adam, three and sister Naja, five.
Jennifer, from Eastbourne, East Sussex, told the Daily Mail: 'I was in the middle of blowing up balloons for Najla and Adam's birthday when the contractions started. Driss was out so I waited for him and he took me to hospital.
'The midwives couldn't believe it when we told them. Three children on the same day must be some sort of record.
'We didn't have a birthday party this year because I was in hospital. Poor Najla - for two of her birthdays she has had to spend it with mummy in hospital.'
Najla was born at 2am on October 7, 2005, at North Staffordshire Hospital when the couple were living in Stoke-on-Trent. She was two weeks overdue and had to be induced.
Adam was born at the same hospital at 8.30pm two years later. He was one week overdue but was born without intervention from hospital staff.
The family moved to Eastbourne two years ago and had Sami at 9.40am last Thursday – another natural birth despite being ten days after his due date.
Mrs Allali added: 'They can grow up together and all have their birthdays together and something to share. It is a special little bond between them.
'The birthdays are going to be a logistical nightmare. If we think ahead, Najla will turn 21 on the same day Adam will be 19 and Sami 16. Imagine that.
'Affording the big day for all three is going to be quite difficult. We haven't really thought about it yet. Maybe we'll have to buy presents throughout the year to afford it all.
'I'm looking for a supermarket or company which makes a birthday cake big enough for three children and all their friends.
'My husband is staggered. He is very proud. You just can't organise something like this. It's astonishing.'
Roger Heath-Brown, professor of Pure Mathematics at Oxford University, said the odds of the couple's children all being born on the same date were 48,627,125 to one.
