9 days into our 7 year old DC’s isolation which ends tomorrow & my DH has just tested a big clear + after having felt a bit odd for a few days but daily negative tests..has sounded like he had a cold today. On the plus side he did a nose only LFT with the nose & throat tests & it was clearly positive almost immediately ( we’re awful with the nose & throat type LFTs so were saving our last box) 
.. we stupidly thought we’d escaped it.
