With identical triplets, the Penn family of New York just got a whole lot bigger.

Identical triplets, coming from a single egg, only come around once in every two hundred million births.

So much for baby steps...

With not one...not two...but three identical babies, the penn family of new york just got a lot bigger....

 Allison Penn, Mother of triplets, saying:

"They are doing amazingly well. We were told expect them not to come home for several weeks. They were born so healthy they came home with us and we were hoping for a little time to prepare but here they are. It's been wonderful."

Wonderful....and amazingly rare! Identical triplets, coming from a single egg, only come around once in every two hundred million births.
