The father of seriously ill toddler Alfie Evans says his son has been breathing unassisted after his life support machine was switched off.
Parents Tom Evans and Kate James have lost a series of legal challenges to continue treatment for the 23-month-old, who has a degenerative neurological condition.
The couple from Liverpool want to move their son from Alder Hey Children's Hospital to Rome where they say doctors are willing to treat the little boy.
Speaking outside Alder Hey, Mr Evans said doctors were "gobsmacked" that his son was breathing nine hours after his life support ended.
"He's still breathing now," Mr Evans said.
"It's come to a point when his mum's actually asleep next to him so she can go to sleep, she feels comfortable with him."
Mr Evans said it became obvious he was breathing "within a few minutes" of life-support being withdrawn on Monday night, although doctors re-intervened after he asked them to help.
He added: "Because he's been doing it for nine hours totally unexpected, the doctors are gobsmacked and I do believe he will need some form of life support in the next couple of hours and I think he ought to be respected and given that."
Alfie has been granted Italian citizenship in a bid to secure his transfer to Rome and last week Mr Evans met Pope Francis, who has voiced support for the couple.
In February, a High Court judge ruled that doctors at Alder Hey could stop treating the youngster against the wishes of his parents.
Mr Justice Hayden said he accepted medical evidence which showed that further treatment was futile.

Court of Appeal judges upheld his decision, while Supreme Court justices and European Court of Human Rights judges refused to intervene.
Hundreds of Aflie's supporters gathered outside Alder Hey on Monday as police were forced to block dozens from trying to storm the hospital building.
