A few families I know have isolated in their own bedrooms when one of them has tested positive. Then a week later another person gets it. Etc
Currently all 4 of us have covid and as we have been boosted and it's a mild variant we are managing to look after each other. It's still a nasty virus but none of us are seriously ill. The kids are old enough to get themselves snacks and drinks. It would be different if they were babies though.
