The grandmother of a critically ill eight-month-old baby has said her family will continue to fight a ruling to withdraw life support.
Medics have been told they can withdraw support for Indi Gregory, who has mitochondrial disease.
The family's latest challenge to the High Court was dismissed on Saturday.
A protest against the ruling was held outside Nottingham's Queen Medical Centre (QMC), where Indi is being treated, on Sunday.
Indi is receiving round-the-clock care for her condition, which prevents cells in the body producing energy and is incurable, according to the NHS.
Lawyers representing her parents, who are from Ilkeston, Derbyshire, said they were considering their next move after judges dismissed an appeal against a ruling that said Indi could not be transferred to a hospital in Italy for treatment.
Speaking at the protest, attended by more than a dozen parents and supporters, Indi's grandmother Nicola Thomas said Indi was still a "happy little baby".
"We want Indi to live," she said.
"We want justice for her. We just keep getting refused and I don't see why we should.
"It's an eight-month-old baby at the end of the day and it's her life and we're all heartbroken.
"There's definitely hope. We're still going to fight. We're going to keep going until there's no more fight left."
Indi's parents are being supported by campaign group Christian Concern and its sister organisation, the Christian Legal Centre.
Dr Keith Girling - medical director at Nottingham University Hospitals NHS Trust, which runs the QMC - previously said: "Cases like this are incredibly difficult for everyone and our thoughts are with Indi's parents at this time.
"Our priority remains to provide the best possible care for Indi and to support her parents through this process."
