I currently have covid, got tested last wednesday and my isolation period finishes on the 25th. I'm isolating with my teenage son but due to go back to work on the night of the 27th where the grandparents were planning to look after him. He is asymptomatic so far and i'm on day 6 of symptoms. They have told me tonight that they don't want to look after him in case my son has caught covid off me on day 9 and then goes on to infect them (understandably as they are vulnerable). Has anyone else had issues with this and how did you get round it?
