The baby girls were born to a mom with an extra uterus. Laurie McCarron got to hold her twins for the first time Thursday. They were born prematurely on Monday and had been in the neonatal intensive care unit.
The babies are now off oxygen, nursing and doing well. It's a big relief considering their mom's rare condition.
"What's called uterine didelphys, where essentially you have two separate uteri and two separate cervixes," said Dr. Adam Urato from Tufts Medical Center. "Laurie's condition we see in about 1 per 1000. Some have estimated it to be even rarer than that- 1 per 3000, 1 per 10,000."
McCarron calls the little ones her miracle babies. They will be joining two big sisters already at home.
