"For example, in order to be with Darcy for his second transplant his parents will have to spend a further £900 on parking alone, this is with a 50% reduction - despite the Governments recent pledge of 'free-parking' from 1st April 2020."
Darcy has taken part in clinical trials with chemotherapy drugs alone costing over £40,000.
Sun Online has reached out to Sheffield Children's Hospital for comment.
