The formerly conjoined twins from upstate New York made their public debut Thursday at Children's Hospital of Philadelphia.
The twins were joined at the lower chest and abdomen.They shared their chest wall, diaphragm, and liver. They underwent a seven-hour surgery, performed by a 40-member medical team.
Surgeons say the twins are thriving and both are doing very well. Allison was discharged from the hospital this week, while Amelia remains there.
"It's been a pure roller coaster of emotions, but I wouldn't trade it for anything," said Shellie Tucker, the girls' mother, who says the family's faith helped them through this journey.
She describes Allison as the feisty, loud one, while Amelia is more laid back and easy-going.
The surgery was the 21st separation of conjoined twins performed at the hospital.
