In bringing up children, every parent
watches eagerly the child’s acquisition (学会) 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.
