My ds went into pre-school today and went over to where they can get themselves a drink of water. I have never really noticed before but they have a plastic jug of water, 5 cups and a small bowl of cold water on a tray. What they do is pour their drink, drink it, swill the cup around in the bowl and put the cup back on the tray where another child inevitably re-uses it and does the same. Well, i just had to speak up and tell the nursery teacher that i think it's unhygeinic and a sure fire way of swapping germs. What would you have thought?
