It is usually a policy for children who have an elevated or depressed temperature to be kept at home for at least 24hours after their temperature returns to normal. The reason for this is that staff are first aid trained, not medically trained and don't have the staff numbers to care for a sick child. As you are experiencing, illness spreads really fast in childcare if sick children are brought to the centre and staff aren't vigelent In supporting families to keep sick chn at home.
It sound like the staff at the childcare centre could do with reviewing their practices( Staying healthy in childcare 4th edition or 5th edition if its been released) heres the link http://www.nhmrc.gov.au/_files_nhmrc/publications/attachments/ch43.pdf

If you haven't been called when you thought you would be... I wonder how many other families havent been called to collect chn who are sick resulting in your daughter getting sick.
Good luck, I hope your little one feels better soon and the dr shows some support and empathy next time you see them!
