WEATHERFORD (CBS 11 NEWS) – Jaclyn and Chad Martin already had their hands full running after their 13-month old twin boys, Grayson and Garin.

When they found out they were having twins Jaclyn remembers thinking, “We were really surprised about the boys.”

Just this week, the family added another set of twins.

This time, identical baby girls named Hayden and Harley.

The baby girls were born Monday night at Weatherford Regional Medical Center.

“More than anything I was shocked to hear twins again,” says Chad Martin. “I didn’t believe it at first.”

Mom Jaclyn admits it’s a little easier, “I know what it’s like – with the boys – I was so scared to be alone with them.”

The parents say they are lucky they have a lot of help and so far it really hasn’t been all that bad.

“We really don’t know any better either,” says Chad. “It’s been twins both times.”

Their biggest challenge so far has been telling their baby girls apart, so they are relying on their hospital wrist bands.

Twins run in both parents families.

Jaclyn’s dad has twin sisters and his great grandmother had four sets of twins.

Chad’s mother is a twin herself.

So what are the odds?  In the Martin’s case, it happened without using infertility.

“It might be one in 10,000,” says Dr. Stephen Stamatis who delivered both sets of twins. “It’s pretty rare. It’s the first time I had actually that I had a patient with consecutive pregnancies with twins.”

The Martin’s are thinking about the future.

They say they can’t wait to see the relationship with their boys and girls.

Though they are very excited, they admit it’s a little scary too.

“We’ll have four teenagers at the same time that will be driving,” says Jaclyn. “Needing cars – and going to school.”

So is this it for the family?

“Ten years from now we wanted more. It might be more reasonable in the near future.  No – No more for now,” says Jaclyn laughing.

By the way, Dr. Stamatis say their chances of having another set of twins is now one in 50.
