Corey Edwards died aged 5 just days after watching his mother and father marry in front of him.
Here is a picture of the Edwards family on their wedding day.
From left are Corey Edwards, 5, Isabelle (front), Jemma, 21, and Craig Edwards, 28, holding Caitlyn, 6 months.
Corey was born with a congenital heart defect. He went through eight traumatic open heart surgeries in a bid to save his life.
He had one wish – to see his parents get married. However, due to his poor health, their plans had constantly been put on hold.
But Corey's condition deteriorated after he was admitted to hospital in January with a cold. His parents were told he might only have days to live.
So the staff at Bristol Children's Hospital helped them marry at his bedside on Saturday.
Corey held the wedding rings.
Corey's father described it as a "special day".
He told ITV that he and his wife thought they would "cheer him up a bit". He added that Corey was very proud: "He looked very handsome. I think he really enjoyed it, which was the main thing."
