So how do you label a behaviour? A child bites, so you just say you shouldn't bite? Naughty is a descriptive word, not a label. If your not allowed to use naughty, you end up with bad, unpleasant, rude, painful etc. Really don't see the point in banning one negative word for other negative words
"Naughty isn't descriptive enough. A child bites so I would say "don't bite - it hurts" - short, sharp and an explanation
Child deliberately breaks their toy. So you say that's destructive? Doesn't mean you have a destructive child, just destructive behaviour
I would tell them the consequence "don't do that, it will break the toy then it won't work any more" - if they continue to do so its the natural consequence.
In a school or nursery setting I can see why they don't want to use naughty, as it can become a label for that child, but in a home setting we, as adults, can tailor the wording to the behaviour and the child
I've never used the word in either setting.
