Bhutanese twins Nima and Dawa still can’t bear to be apart after undergoing separation surgery.

The 15-month-old sisters spent their whole lives joined at the torso until they were successfully separated at the Royal Children’s Hospital last week.

The hospital has released photos of the twins lying side-by-side and with their legs intertwined. 

The twins aren't straying too far from each other after their surgery.

Nurse coordinator Kellie Smith said the pair were a delight to look after and their personalities were shining through.

“We try to have them a little bit apart, but they manage to bum shuffle back together and have their legs intertwined, always,” Ms Smith said on Thursday.

“They’re really cheeky, they’re not far from one another at any time at all and they’re still in the same bed.”

Like most young children, the girls are fond of The Wiggles and are enjoying attention from the nursing staff.

The twins are recovering well from their operation at the Royal Children's Hospital in Melbourne less than a week ago.

“They love it when they’re watching The Wiggles and they do little dance moves with their hands,” nurse Megan Collins said.

Though the pair are mostly in good spirits, they don’t like to be separated and still sleep in the same bed.

“Nima, I would say she wants to be closer to Dawa, than what Dawa does to Nima,” Ms Collins said.

“Dawa is kind of being a little bit more active at the moment and a bit more cheeky.”

Lead paediatric surgeon Dr Joe Crameri said the girls were healing well but it was premature to say when they would leave hospital and return to Kilmore to recover, or home to Bhutan.

“The area that we repaired on their tummy wall seems to be dealing with the strain quite well,” Mr Crameri said.

“In reality the girls have got to be well, they’ve got to have all their attached tubing out before we send them back to Kilmore and we’re a little way off that at the moment.”

Mum Bhumchu Zangmo was overjoyed and relieved her daughters were doing well, Children First Foundation executive Elizabeth Lodge said.

The foundation helped bring the girls and their mother to Australia for the life-changing surgery.

“She’s very relieved, incredibly grateful and she has amazing support from the Bhutanese community here as well,” Ms Lodge said.

“They’re enjoying their independence but they’re also enjoying having proximity to each other and (are) still able to pull each other’s hair, which is lovely,” she said.

Two children, Jack and Annie, who are staying at the retreat are looking forward to seeing the twins again so they could all play together, Ms Lodge said.

The girls and their mother arrived in Australia in October but waited weeks for the surgery while twins built up strength.
