A High Court judge is this week expected to decide whether doctors should stop providing life-support treatment to an 11-month-old boy being cared for at a London hospital.
Specialists at King's College Hospital say giving further intensive care treatment to Isaiah Haastrup is "futile, burdensome and not in his best interests".
Isaiah's mother, Takesha Thomas, and father Lanre Haastrup, want treatment to continue.
Mr Justice MacDonald is scheduled to analyse detailed evidence at a trial in the Family Division of the High Court in London on Monday.
Barrister Fiona Paterson, who has represented King's College Hospital NHS Foundation Trust at hearings, has told Mr Justice MacDonald that Isaiah was born at King's College Hospital on February 18 2017 with a severe brain injury thought to have been caused by a deprivation of oxygen.
She said he was "ventilator-dependent" and being cared for in a paediatric intensive care unit.
Doctors did not think there were any "further investigations or forms of treatment" which would benefit him.
