Sooner or later the child's wishes will become larger than our capacity to satisfy them, and this unexpected denial will cause him more torment than the lack of that thing he demanded of us. And, from that pain will come hate and loathing. Both extremes, of too little or of too much satisfaction of their wishes, are harmful to the emotional development of children. Because of the previously mentioned reasons, parents should not leave their children alone at home, with the older ones caring for the younger ones, if the oldest child is still less than twelve years old. Each child's temperament is a matter of luck.
Nature selects it at random, without asking the parents' opinion.
So then, some children are born with an abrasive temperament, are strong-willed, or may be easily angered or irritated. Parents or would-be parents have to be prepared for the fact that EACH of their children will come with his or her OWN temperament, and they have to be prepared to rear and educate each one of their children working with THAT particular child's innate temperament. What is important for the development of that child as a true human being is not the child's temperament, but his or her character. Character is the result of the child's innate temperament plus the rearing given by his or her parents. Above all, parents need to spend TIME with EACH ONE of their children.
