Some 27 hours into a marathon operation at a Melbourne hospital to separate conjoined twins Trishna and Krishna, supporters remain optimistic the toddlers will pull through the risky procedure unharmed.
  
Surgeons at Melbourne's Royal Childrens Hospital began the surgery to separate the two-year-old twins, who are joined at the head, about 8.30am local time on Monday.
  
Just after 11am on Tuesday surgeons were still working to separate the girls' brains.
  
The Bangladeshi orphans arrived in Australia just over two years ago through Moira Kelly's Children First Foundation.
  
Foundation Chief Executive Margaret Smith said she was trying to remain calm as surgeons work to separate the twins' brains millimetre by millimetre.
  
"The wait has been very drawn out and it has been very stressful," she said.
  
"It's going very well, we have just got to be patient."
  
Smith said Krishna is the quieter twin while Trishna is noisy.
  
But Krishna gets her own back by pinching Trishna's ear, Smith said.
  
She said she was heartened by the news Krishna's kidneys were functioning again after some earlier problems.
  
"So we got very excited over five millilitres of wee," she said.
  
"We are actually pretty excited and optimistic."
  
Smith said Kelly was in good spirits and catching up on some well-earned sleep.
  
Surgeons have put the chance of the twins coming out of the operation unharmed at only 25%.
