Green snot and fever is a no go! Sorry TMI but that is what my childcare/kinder says, if they have a sniffle and feel well it's ok but green is a no-go zone! I sent my DD today with a bit of a cough and runny nose as well because she was happy to go, and I know they will call if she seems to be getting worse. She's at the end of a cold though and her coughs last weeks so I have to send her with a bit of it! HtH!
