There has been a continuous discussion between two separate persons' viewpoints, whether the parents or TV and friends have the greatest impact in kid's development, I totally agree that parent have the most significent role in child's development.
There is no doubt that parents play a vital role in their kid's development. Hence,there are many factors that contribute consequentley in children growth, firstly, the environment that kid has grown up. For instance, the kids who grew up within rich families, they probably will get better chances to have a higher level of eduction, secondly, the educational background of the parents also contribute in kids development, these kids having educated parents they might have better learning opportunities than those kids with uneducated parents!
Thirdly, parent upbringing style, for example, how they treat their childern in a variety of situations, when children are making good habits, new achievements or learning somthing new, how parents will be showing the recognition and appreciation in order to encourage them, simillarly, when children are making bad attitudes, what kind of punishment they will be using.
On another hand, some people argue that media or friends have the most influence, the friendship is influencing the child's thinking and kids may adopt some new attitudes that are not acceptable for their societies, also the media is showing a lot of contents that not suits all different ages or cultures.
In conclusion, I believe both of two perspective is reasonable whereas I believe that parents have the most influence on their childern as they have the full control to shape thier children's life style, especaily, in their initial years of life.
