All three children of the couple were born on the same day, though none of them were due on that day. It is incredible that the third child was also born on January 29th- the same date as her older brother and sister.
Brother Robin was born on January 29 in 1994 and sister Rebecca was born on January 29 in 1996.
Martin, 40, said that the family were amazed when Ruby arrived on the same day last month weighing in at a healthy 7lb 7oz.
"We can't believe it. People are always surprised," The Sun quoted Kim, as saying.
What's more incredible is that none of the kids was even due on January 29.
Robin was two weeks early, while Rebecca came a week late.
Ruby was due to be born on February 7 but doctors told mum Kim, 41, that her baby would be born early and as she had to be delivered by caesarian section the only available date was the same birthday as her siblings.
Experts calculate the odds of a couple having three children all on the same date are 7.5 in a million.
