So if I follow nhmrc guidelines and my drs advice I am being irresponsible? I go to the dr to see if they think my child is contagious. If they don't think my child is contagious do I need to exclude them because they still have a runny nose after an attack of croup? How about my friends child who has a runny nose for 6 months of the year and is on antibiotics all winter? Should he not attend childcare and later school for half a year?
