DS2 age 6 tested positive for Covid on Sunday. Myself, DH and DS1 (8) finally got lateral flow tests through today and are currently all negative. By the guidelines, I should send DS1 back to school tomorrow but do I? The liklihood is that he is going to catch it, particularly if it's Omicron which it probably is. Do I risk sending him back and infecting his classmates and a whole museum during a school trip on Thursday too or keep him off? Before Omicron I'd have happily sent him in with a negative lateral flow, but having seen for myself how it's spread through our family this Christmas and New Year I don't know what to do.
