I have two children in an infant school. I'm under no illusion that one, or both, bubble will close at some point. The rule seems to be that when a bubble closes, that sibling needs to stay at home but, assuming no symptoms, all other members of the family can continue their lives as normal.
How do I take the second child to school while the first one isolates? Children are 6 and 4 and we live a three minute walk from the school for reference.
