is it right for a grownup say "Don’t be a fool ??" or "stupid" to children

though i'm still single, i think it's better not to say such words. cause it will hurt the children very much. maybe we can tell them why they cant do it, or what better ways they can choose, etc.

The best way is talk and reason with children that the course of action they have opted for is not the right one.We can repeat the same point when they are in a better mood or give positive reinforcement like a reward to bring about a change in the way they do things which are not acceptable to us.Instead of rebuking the children we should not reward them when they resort to actions which are negative or not agreeable to us.We should make the children have self confidence and this wont be achieved by lowering their self esteem.

Saying those words is detrimental to the psychology of the child. He will grow up to think that he has been a fool, stupid and still hasn't changed. Parents often say those words with the hope that their children don't repeat their mistakes but it's not the correct way of correcting them. The best - as far as I'm concerned - is to tell them why they shouldn't do a particular act, and the effect of not adhering to your advice. This works if your child is an obedient one. However, for the more stubborn ones, perhaps a different approach could be used - something that does not put a permanent imprint in their minds that they're useless.
