The Pennsylvania parents of twins that were born conjoined at the torso and share the same heart have decided not to let doctors separate them.

Doctors were not certain if twin brothers Garrett and Andrew Stancombe would survive once they were born in April. Not only were they born alive, the twins are now at home doing well, CBS Pittsburgh reported Thursday. But the parents will not go through with surgery to separate the brothers- who also share a liver- because they may not survive.  

"They could be here with us tomorrow and gone the next second," the boy's mother, Michelle Van Horne, told the station. "A month down they could be gone. They could turn into teenagers. We don't know and that's the difficulty."

Van Horne and the twins' father, Kody Stancombe, found out the boys were conjoined at the end of her first trimester. Doctors told Van Horne her twins could be stillborn. They also said the twins could be born alive but die within a few hours.

"It was difficult hearing. I was scared and nervous," the mother told the station.

Garrett and Andrew were born connected from the chest to their bellies on April 10 and were home four days later. The boys are eating, sleeping regularly and even act like brothers when they poke each other in the eye, the station reported.

"They're breathing good. They're crying. They're doing everything a normal infant would do," Van Horne, who also has another son, told WPXI Pittsburgh.

According to the University of Maryland Medical Center, conjoined twins are born one out of every 200,000 live births

Since Andrew and Garrett are conjoined at two vital organs, the parents believe it is best to leave them as is, even if they don't know how long they will be alive.

"They'll continue to fight until it's their time. We will love them and cherish them until that moment and continue even after," Van Horne told WPXI Pittsburgh.
