A dad who found out his son had leukaemia in a hospital car park said Covid rules banning both parents from going to appointments were “cruel”.
Covid rules mean only one parent can go with him, with his father Jason having to wait outside for hours for news.
Cardiff and Vale health board said it followed Welsh government guidance and made allowances “as appropriate”.
Carson, from Ammanford, Carmarthenshire, was diagnosed with acute myeloid leukaemia at the start of lockdown last year, and had a bone marrow transplant in Bristol in October.
Since then he has been going to the hospital in Cardiff for treatment and check-ups, but while his mum Carrie goes with him, his dad Jason has to wait outside.
“It’s absolutely cruel that two parents can’t be there to support their children,” said Jason, who cannot go inside to hear updates from consultants due to the one-parent rule.
