阅读理解。 

    Honestly, since my daughter was born, I have thought a lot about how to raise a child. I once

heard a story that told about when a baby was born. The story said that when a baby was born,

a new master was born. The parents of that baby would become the servants. The question is:

Why? Based on my observation, this phenomenon is true. Most parents who don't pay much

attention to their kids have difficulties with their kids' attitude.

    I'll make a comparison of how two families raise their children. The first one is a family with

three children. Both mother and father never say "No" to their children's demands. As a result,

all of their children became stubborn and won't listen to their parents' words, "We can't."

    The second family educated their children strictly from one year old to high school. The parents

never approved or agreed directly to give their children what they wanted. They always postponed

one or two days, even if they could afford it. Due to the way their parents educated them, these

children understood that if they wanted something, they had to wait or they had to make an effort first.

As a result, all the kids from the second family successfully graduated from university on time.

    In my opinion, if we want to be successful parents and raise our children well, we have to start

disciplining them when they are toddlers but not wait until they become teenagers.
