You'd be furious at alot of people then, I know of alot of times where parents have tried to sneak children back early at work with excuses or just not telling us they were even sick to begin with (as in the older sibling letting the cat out of the bag about johnnie vomited this morning). I imagine this happens an awful lot in the school system. I know at the local prep, children sent home vomiting are permitted back the next day - not even 24 hours later. Sadly not all parents even think twice about it.
Yup! I suspect I would!
Even on Friday sitting with Iain at Kindy, A dad asked his little boy who was next to me at the table if his tummy was feeling better? I sat there & thought WTF?! Then he went up & told the teacher that his son had complained of a upset set tummy, but no vomit or poos. I still sat there thinking are you serious! BUT in my defense it is the domino effect that concerns me that if one of the kids brings home something from a child who was known to be unwell & still sent to school then Im in for at least 2 weeks of it with my kids. Plus DH is a real germ freak so if one of the kids is sick then he is a mess!

I hope your school week gets off to an ok start as best as it can. I know what its like to have kids with issues & school. My oldest is starting off by doing a week of only an hour & half in the afternoons at school & had to have the 2nd day off with a "sore throat".
