A moving photograph shows a tearful father being reunited with his son after he gave him part of his liver in a life-saving operation.
Matt Price's son Callan entered a coma when he was just four-days-old because of a rare genetic condition poisoning his brain and body.
His devastated parents, from Norfolk, were warned it was unlikely he would make it through the night.
Although he pulled through, Callan spent the next five months on dialysis, before doctors warned his only hope was a new liver.
Rather than go on the waiting list, Mr Price, 39, offered to donate the 20 per cent of his liver that Callan needed. The pair went under the knife for 10 hours on February 1.
More than eight months on, the now 17-month-old is 'exactly like any other young boy', with just a scar across his abdomen to show what he has been through.

Callan (pictured with his father) spent months on dialysis in hospital. Doctors warned his only hope was a liver transplant. To save him going on the waiting list, Mr Price offered to help
Callan's condition, ornithine transcarbamylase deficiency (OTCD), affects between one and nine in every 100,000 people, statistics show. It causes ammonia to accumulate in the body.
Callan started making grunting noises and was struggling to breathe as soon as he was born.
Mr Price, also father to Ronnie, five, and Tom, two, said: 'We thought there was nothing to worry about.
'The hospital actually took him off us when he was 40 minutes old but they brought him back to us and said he was fine.
'They said his breathing difficulties would calm down in a few hours but it didn't and he kept deteriorating.'
After being rushed to intensive care, Callan later went into a coma.
Mr Price, who shares his children with his wife Jen, 36, said: 'We went into the hospital thinking we were going to come home with a newborn baby but he was in a coma four days later.
'We were told he probably wouldn't make it through the night, we were told to expect the worse and hope for the best.'
Callan was transferred to a specialist unit at St Thomas Hospital in London, where he was diagnosed with OTCD.
The newborn was hooked up to a blood dialysis machine to try and clear the ammonia out of his system.
Mr Price, a project director at an events company, said: 'We had to try and get our heads around everything while Callan was in a coma.
'Callan was poisoning his own brain. His brain was closing down as his ammonia level was so high.
'He was struggling to manage his protein intake, he was breaking his own body down.'
Callan spent much of his early life in hospital (seen left) and even entered a coma at just four days old. Since the transplant, the now 17-month-old (right) is like 'any other young boy'
Mr Price (pictured left with his son) believes Callan's future is 'bright'. The youngster (pictured right in hospital) became severely unwell when the ammonia caused his brain to 'close down'
The youngster came out of the coma after five days, but still needed
