Our kids put their shorts on for playtime, like they would for pe. I agree that little girls should be able to do anything they want to, wearing whatever they want to, but look at it from schools perspective. If you girl ended up in facebook, skirt over head, being commented on by idiots, and that photo had been taken by someone passing the school fence or overlooking the grounds, dont you think school would be partly responsible for not recognising this risk? the local authority would go to town on the head and governors for not spotting this. this is the sort of shite we have to risk assess on a daily basis. Imagine the risk assessment we have to do to take kids out in public places! Trips you should be excited about, you spend hours writing down what you will do about paedophiles, child snatchers, terrorists... The teacher in question probably agrees with you entirely.
