A couple have released photos of their newborn conjoined twins after defying doctors who advised they terminate the pregnancy.
Chelsea Torres, 22, from Blackfoot, Idaho, gave birth to Callie and Carter at 37 weeks in January by cesarean section following a nerve-racking pregnancy.
Doctors warned Ms Torres that the babies would unlikely survive beyond the 11-week pregnancy mark.
Yet, Ms Torres and her husband Nick, 22, have been assured that the twins, weighing 4.5lb (2kg) each, are healthy.
And despite seeking out the best surgeons in the country to separate the girls, they were told the girls are ‘too healthy’ to require separation.
Between 40 and 60 percent of all conjoined twins are stillborn, with just over a third of those who do survive living less than a day, according to data from the University of Maryland.
Callie and Carter are omphalo-ischiopagus twins, which make up less than 5 percent of conjoined twins.
This means they have just two legs and one pelvis between them, but have two separate torsos that face each other.
Due to the type of condition the girls have, they do not share any vital organs.
