Be aware that childrem learn fast.

"F*** you," he shouted to the sister.
The mother was shocked at the words the first time she heard it from her son. "What did you say?" she inquired the little son who has just returned from the kindergarten.
Laughing with delight at the mother's astonishment at his mastery of words in just a few hours, he replied, "I said f*** you."

Yes, children learn real fast and they are so innocent about what they had inadvertently learned that they they reveal their knowledge to all they come into contact with. In their innocence, they believe all knowledge is good, be it vulgar or not. So, in a way, it is easy to know what they have just learned so that parents can remove the dirt and filth immediately before the use of such words become a habit.

It depends upon the parents whether what has been learned will be in usage. Learning that such words are in existence and there are people using them is acceptable but if it comes into the child's everyday language, then he has acquired the use of unnecessary language. Such language is not useful, in fact detrimental to the child's welfare, in life. As adults, when we understand that someone has been brought up with the use of such language, we might accept it but there are times when such use of language becomes embarrassing besides it being unnecessary.

So parents should be aware of what their children have learned and discourage or encourage the usage of the newly acquired knowledge. If unnecessary or harmful knowledge has been learned and practised, it could lead to the child's future downfall.

One such harmful habit is acquired from friends or pushers who invite unwitting children to try smoking and from there to cigarettes spiked with drugs. And if the child learns that his parents dislike smoking, the child may even have the new knowledge concealed from the parents. However, parents who are aware or close with the child will be able to smell the difference. The smell of cigarette smoke in the mouth or fingers of smokers is strong. (When I was a teacher, I had been able to detect the smell as a student walked past me after returning from a smoke. Upon searching the pockets I had found cigarettes and a lighter in such a student, evidence that he smoked.) If the parent were to explain to the child the dangers of smoke in our lungs, then it might prevent further practice of the activity.

Of course, not all knowledge or activity is bad, just as not all knowledge or activity is good. Knowing a child's knowledge and interest early, parents can assist the child to be involved more deeply into it and have it become a hobby or stepping stone to further knowledge and interest in books with such knowledge. Interest in books can lead the child to improve his language capabilities and other interests. And from here, the sky is the limit as far as the acquiring of knowledge is concerned.

Besides knowledge, another important aspect of interests is the eventual realisation that there is so much to know, learn and do, making life so meaningful and wonderful. It makes life not just eating, resting, sleeping and working but living and enjoying each day, thus such a person looks forward to each precious minute with eagerness. That's what makes life precious!
