     In bringing up children, every parent watches eagerly the child's acquisition of each new

skill-the first spoken words, the first independent steps, or the beginning of reading and writing.

It is often tempting to hurry the child beyond his natural learning rate, but this can set up

dangerous feelings of failure and states of worry in the child. This might happen at any stage.

A baby might be forced to use a toilet too early, a young child might be encouraged to learn

to read before he knows the meaning of the words he reads. On the other hand, though, if a

child is left alone too much, or without any learning opportunities, he loses his natural enthusiasm

for life and his desire to find out new things for himself.

     Parents vary greatly in their degree of strictness towards their children. Some may be

especially strict in money matters, others are severe over times of coming home at night or

punctuality for meals. In general, the controls imposed represent the needs of the parents and

the values of the community as much as the child's own happiness.

     As regards the development of moral standards in the growing child, consistency is very

important in parental teaching. To forbid a thing one day and excuse it the next is no foundation

for morality (道德). Also, parents should realize that "example is better than precept". If they

are not sincere and do not practice what they preach (说教),their children may grow confused

and emotionally insecure when they grow old enough to think for themselves, and realize they

have been to some extent fooled.

     A sudden awareness of a marked difference between their parents' principles and their

morals can be a dangerous disappointment.
