“They’re called mono di twins, meaning that they had their own sacs, but they shared the same placenta, meaning that they were going to be identical,” she said.

“Mo di twins as it is, it’s like very rare. And then you throw Down syndrome on top of it, it’s like one in 2 million.”

Despite their rare condition, Savannah said they are just like any other child.

“They have feelings. They have a beating heart. They know how to talk. They know how to do things you do. They will get there,” she explained. “Like I said, it may be a step behind but they’re going to do it. I’ve learned these kids are feisty little things and happy little things.”
