A mum and dad from Peterborough have started a campaign to find their baby a new heart.
Benjamin Hardy was born unable to pump blood properly, and he is waiting for a transplant.
Benjamin's parents are trying to raise awareness of his life threatening condition and are urging people to sign up for organ donation.
Four month old Ben is being treated at the Freeman Hospital in Newcastle, he's never been well enough to go home.
Benjamin's condition is called hypoplastic left heart syndrome. It means the left side of his heart is smaller and doesn't pump blood properly.
