But Tom has disputed the diagnosis, arguing that Alfie was "still fighting" and was "comfortable" despite being taken off life support three days ago.
Alfie's parents have been embroiled in a legal battle to get treatment for their son who has been cared for in Liverpool's Alder Hey Hospital.
The terminally ill baby Alfie Evans could be taken home within a day or two after a meeting between his parents and doctors at the hospital where he is being cared for.
"We submit there is a likelihood of Alfie having some pleasure in life", he said.
"We are leaving from Jct 14 mayfield and walking to to main street and back again".
The couple have apparently exhausted all legal options to continue their son's treatment overseas after losing their "last chance" appeal to overturn a High Court ruling to end his life on Wednesday afternoon.
The case has drawn worldwide attention, with the Pope pledging support to the family, and has sparked demonstrations outside the hospital in Liverpool.
Alfie is facing an incurable degenerative neurological condition, and doctors say there is nothing else they can do for the toddler.

On Tuesday, a British judge ruled against the parents and declared that Evans could not be removed and flown to the Vatican for further treatment, arguing it would just prolong the child's suffering.
The Catholic Association then released a statement on Thursday criticizing Catholic leadership in the United Kingdom for siding with the courts.

But High Court Lord Justice Anthony Hayden allowed for British doctors to consider letting the boy go home.
'Some people say it's a miracle.
"True to that legacy, the Pope spoke out in defense of Alfie Evans and the fundamental human rights of his parents to do all they can to save the life of their child".
"As I sit next to Alfie's bedside, every second of every day, it encourages me more and more that he will live for "x" amount of months, possibly years". In a bid to ease transferring the boy to Rome, Italy granted the boy citizenship on April 23, but the court upheld it's previous rulings.
The doctors' letter also called on the General Medical Council to investigate the actions of the staff at Alder Hey Children's Hospital in Liverpool. Since then, Alfie has continued to breathe on his own with minimal oxygen, water and nutrition for more than 60 hours as of press time. Since coming off the ventilator, he has breathed unaided, which Evans said was a "shock" both to him and the boy's mother.
