Until recently your daughter was an amusing kid who did not provide problems. And already today you with horror notice that she is wiped by a sleeve, and tries to decorate the children's speech with some curses... There is a wish to parents of it, or not, and sooner or later children will hear somewhere bad words (even if you also will preserve them against it in every way) And nothing is capable to prevent the child to repeat the heard word - a curse, even without understanding of its sense.
Reaction of parents
Try to inform the child of a thought in time that to use swear words very indecently and inadmissibly. Tell the kid that in the world there are words rescuers, words doctors that bring tranquility and joy, but there are also black, bad words robbers who offend people, hurt. If somebody swears in the presence of your child, then explain to him that this person bad, not well-mannered and hardly people respect him.
Very often adult, having heard indecent statements from lips of the children, begin to laugh that causes desire to repeat curses once again in children and by that again to make laugh people around. However will be more true not to disorient the kid: if he tells a word at which it is possible to laugh in the family circle, in transport or shop, then reaction of you can turn out completely different.
Quite often children appeal to parents to explain value of any given words. In such situation you should not find out where he heard it and who told it. Firmly, but with goodwill tell the kid that you do not want to hear more such words from him. Usually children obey and at your presence will be afraid to repeat curses.
Small instruction for parents
Children tell curses without understanding of their sense, and therefore all is equal to them where to say them aloud. It is not reasonable to punish, shame or abuse the child at all. For him such words this simple combination of letters which a little in what differ from all other phrases and phrases.
You of course can wait when the swear word is forgotten in itself, but too you should not hope for such deal. Very much you watch closely own words: children cannot forbid to tell words which are told by his parents. Read to the kid more, it will well fill up his lexicon, teach to look for replacement to usual expressions and words.
