My eldest son had rather a bit of time away from school last term, because first he was involved in an accident which necessitated him going to hospital. When he recovered from severe muscle strain. he then caught a sickness and diarrhoea bug! This floored him for over a week. once he got back to school, he was there for less than a month, and was hit by yet another bug - followed by a streaming cold and bad cough! I had to go into school in person, or be accountable to the school welfare officer! Once I showed them the dates of illness, visits to the hospital and doctors, and copies of emails that I'd sent to back up phone calls - they apologised!!!! I think they were just following procedures, but I made my annoyance felt. When I asked if they'd rather've had me let my son attend school and pass the bugs onto others, they said no - of course not - so I know I did right.
