Miles Harris didn't think he would live to see his baby born after being diagnosed with severe liver failure.
But just six months on from the diagnosis, and a successful liver transplant later he is looking forward to watching Sebastian grow up.
The 34-year-old Norton Hill School teacher is also preparing to take part in the transplant games qualifiers, with the hope of representing Britain in the finals in South Africa next year.
Mr Harris, who lives in Bath, was diagnosed with primary sclerosing cholangitis two years ago.
The disease affects the ducts in the liver, causing the tubes to become clogged, and he was put on antibiotics to manage the condition.
However the toxins poisoned his blood, and in March he was diagnosed with severe liver failure.
Mr Harris said: "The tubes in my liver became blocked, the toxins were poisoning my body and I became very jaundiced.
"I was told my liver was failing and that I would need a transplant.
"It was quite frightening to hear that, but I knew that it was the only way, and the only thing that would help."
Just 18 days after the diagnosis Mr Harris and his wife Marina, 27, received a call in the middle of the night, and were whisked off to Birmingham Hospital in an ambulance for the transplant.
At the time Mrs Harris was seven months pregnant with their first child.
She said: "It was all a bit of a shock as it happened so fast.
"When we got the call we were told to get up and have a cup of tea while we waited, but the ambulance arrived in ten minutes and we were rushed to the hospital.
"It was very surreal, and a bit frightening as I knew he needed this transplant to survive."
At the hospital Mr Harris had tests done, before the transplant took place the next day.
He said that he started to feel better immediately after.
Mr Harris said: "When I came round my family were all grinning, it was almost like a celebration.
"They could see how my colour had changed straightaway.
"I felt like so many of my symptoms were draining away."
After a three month recovery period Mr Harris was back at work, and enjoying spending time with baby Sebastian, who was born two months after his transplant.
Sebastian was given the middle name of Perera, after surgeon Mr Perera who performed the transplant.
Mr Harris said: "It bought me to tears when Sebastian was born, to see him and know that I will be there for him.
"We named him after my surgeon, who was an absolutely incredible man.
"I feel so lucky to be here."
Mr Harris is now looking forward to the future, and hopes to represent Britain in the National Transplant Games in South Africa next year.
The Games are for anyone who has had a transplant, and feature a variety of sports from athletics, to swimming, and table tennis.
Mr Harris will be taking part in the golf regional tryouts in the spring, and also hopes to compete in cycling and running.
He is also raising awareness of the importance of organ donation, and is urging everyone to sign up to the register.
Mr Harris said: "It would be fantastic to represent my country in the Games, I feel a responsibility to be an ambassador for organ donation.
"It is great that something so positive can come out of something so tragic.
"Organ donation is a life saver, and my transplant saved mine."
More than 10,000 people in the UK need an organ transplant and three people a day die before one is available.
Only 27 per cent of the population are on the register.
