I was talking to my cousin (Well one of them) recently and she was telling me her daughter, who's a Nursery Nurse had moved to a new Nursery.
She said the first Nursery didn't believe in telling children off and felt they should be allowed to "Express Themselves"
So for example, she couldn't tell the wee boy who was on top of a table throwing a tantrum off, because he was expressing himself.
Nor could she say anything if one of them hit her.
