At Harry's kindy they write on the sign in sheet next to the child's name if you need to sign an incident report - so when you go to pick up your child there will be little note next to their name saying 'form to sign' or something like that. They do these for the smallest thing.

My SILs friend had an incident recently at her DD's daycare where her DD got a broken collarbone - and the carer/s had no idea! There was no incident report or anything, and they apparently didn't realise anythign was wrong. It was only when the mum came to pick her up and realised something was wrong and took her to the doctor that it was found. Conveniently the next day the day care came up with an incident report but it was too late - SILs friend is suing them now and I don't blame her!
