A critically ill baby girl at the centre of a life support treatment case is dying, a doctor has told a High Court judge.
Indi Gregory has mitochondrial disease and is being cared for at the Queen's Medical Centre (QMC) in Nottingham.
The hospital said it could do no more for her and has applied to the High Court to end her treatment.
A doctor on Monday told Mr Justice Peel of the "terrible reality" facing the seven-month-old baby.
Indi's parents Dean Gregory and Claire Staniforth, from Ilkeston, Derbyshire, want treatment to continue.
The judge is considering evidence behind closed doors, but has allowed journalists to attend the hearing and ruled Indi, her parents, and the hospital can be named in reports.
He ruled medics treating Indi - and a guardian appointed to represent her interests - could not be named.
The doctor told the judge that keeping Indi on a ventilator would "prolong matters".
He said staff treating Indi had done the best they could and were "very sad".
"She is a little girl we have tried to treat to the best of our abilities," the doctor said.
"The terrible reality is that she is dying."
The specialist described himself as an "expert" in the treatment of seriously ill children.
He said Indi's case was "really difficult", adding that on one day, Indi had "nine episodes of resuscitation to keep her alive".
Bosses at Nottingham University Hospitals NHS Foundation Trust, who have responsibility for Indi's care, have asked the judge to rule on the case.
Mitochondrial disease prevents cells in the body producing energy and the NHS says the condition is incurable.
Barrister Emma Sutton KC, who is leading the trust's legal team, has told the judge that Indi is "critically" ill.
She said Indi had a "devastating neurometabolic disorder", which was "exceptionally rare".
