It is extremely unlikely that she will be able to actually do what her parent instructs her to do. When Mom has to repeat the instruction continually, she may begin to feel frustrated and angry. Jennifer, unable to comply, begins to feel that Mom does not like her because she gives threats and yells at her. Over time, repeated attempts to reason with a child can result in lowering the child's self-esteem. As this process goes on, day after day, the parent gets more and more frustrated and the child develops a very poor self-image.
Children learn through repetition.
They must have the opportunity to practice the same thing over and over again. If Jennifer needs to be taught not to go into the street, she must be shown this lesson over and over again. Every time that Jennifer goes too near the street, she needs to be disciplined, in an unemotional way. Every time she starts to go toward the street, but stops short of doing so, she needs to be praised. After Jennifer has made 20 or 30 trips towards the street, with some trips resulting in discipline and some in praise, she will learn to stay out of the street.
