So do you walk out to each car and check that each child is correctly strapped in to an appropriate child restraint? I doubt it. Never happened when my DD attended a C&K kindy. As soon as we were out of the door they weren't interested in the child. If they had followed us out the door and to the car I would have told them to go jump and mind their own business.
Jerry: I'm surprised that you require an adult to collect Preppies. What about older siblings at the school? Are they not permitted to collect them? DD's school allows responsible older siblings, with the permission of the parents, to collect Preppies from term 3 or 4.
