Hi everyone - thank you so much for all your good wishes.
FL is a lot better today. His temperature is down and he is coughing less. The antibiotics are definitely helping. However, he isn't drinking enough and his kidneys are not functioning properly. Unless I can get him properly hydrated he will have to go to hospital.
So I am at the office for as long as it takes to clear my emails and gather a pile of paper to take home and work on there... while dispensing glasses of water!
