Two boys born joined at their breastbone and hip bones were finally released from a Dallas hospital Wednesday after undergoing separation surgery.
Owen and Emmitt Ezell underwent the nine-hour procedure six weeks after their August birth, ABC News reported.
Doctors initially thought the two would not survive very long or need to undergo several painful surgeries since they shared some vital organs, such as a liver and intestines.
The baby boys, however, are doing well and have been released from the Medical City Children's Hospital to spend several weeks or months in a rehabilitation center.
Dr. Tom Renard, the lead pediatric separation surgeon, said the boys have more than doubled their size since birth and are alert and thriving.

The family told ABC News they feel joy and elation, but still feel nervous.
“You can never predict what can happen but these little guys are definitely survivors,” said David Ezell, the father of the twins.
“I'll finally have my family together but we are about to face some serious challenges,” he added. “The really frightening life-or-death stuff is behind us, but now we worry how about how we are going to pull the rest of it off.”
While in the rehabilitation facility, Jenni and David Ezell will learn how to clean their sons' tracheal tubes, manage the home ventilator that helps them breathe and work with Owen and Emmitt on rehabilitation exercises.
Jenni Ezell said the tasks seem daunting, but she's looking forward to caring for her children without relying on a team of doctors and nurses.
“I think my 7-year-old will at least help with diaper duty, though I guess it depends on what kind of diaper we're talking about,” she laughed.
The mother said she's grateful their biggest challenge will now be learning to tell the boys apart.
Dave Ezell told ABC News anyone who spends a little time around Owen and Emmitt can easily tell them apart from the different personalities.
“Owen opens his eyes a little bit wider and is a little more excitable. Emmitt is more relaxed. His eyes are usually softer and more closed,” he explained.

Conjoined twins are uncommon, only occurring in about one in 50,000 to one in 200,000 births.
Dr. Renard said odds of survival for conjoined twins are typically around 40 to 50 percent.
