Conjoined twins Nima and Dawa go home after being separated – look at them now!

Two little Bhutanese twin girls who underwent separation surgery in Australia have been allowed to go home to Bhutan.

Twenty-month-old Nima and Dawa flew home with their mother, Bhumchu Zangmo, and had an emotional reunion with their father, Sonam Tshering.

Mr Tshering said it was like a miracle, and brought the girls to a monastery to light a lamp in prayer.

The girls shared a liver and were joined together from the chest to pelvis pre-surgery. After separation, they still liked to lie with their legs entwined. They are now learning to walk but still sleep in the same bed.

The medical team who worked with the twins say they expect that their lives will go on as normal now.

“We don't expect there are going to be any problems, they'll continue to make their milestones and go forward in leaps and bounds form here on in,” the Children's First Foundation's Deb Pickering told ABC News.

“They're much the same as they were when they were together, we've got one that's very much more outgoing and one that's more placid — Nima's the outgoing and Dawa's the more placid.

“They're just developing into beautiful little girls in every way.”
