Parents should be strict some times with their children . If Parents give complete freedom to their children they can go out of their hand. If parents are not strict with their children their children doesn't hear to them and do things they want to according to their wish . Parents some time think that if they shout on their children or behave strictly with their children it will hurt their children, make them sad or even spoil their relation with them.
Parents should make a time table for their children for their hobbies , sports, going outdoors with friends , watching television etc. Maintaining a proper schedule for different things will help their children to concentrate on studies and enjoy life also. If parents try to rule our their children or fully restrict them they may then also get out of their control as doing anything over is wrong. That goes same with restriction put on children .
Some children hate being restricted in doing some things as they think that they have grown enough to have freedom and do things they like but they may be wrong as thus they are thinking of enjoying their life and not their future carrier. As one grows up and build sa good carrier he then remembers the shouting's he received from his parents which helped him to achieve what he has got. He then realised if his parents didn't control him then he would have achieved such things in life.
Whenever parents expect a lot from their children or shout at them just to get good marks it may harm their children emotionally and thats why their are cases seen of suicides done by children. Their should be good relationship maintained between the parents and children and parents should understand the capability and interests of their children .
Parents should't support the children in wrong things they should be totally against it as if children start doing wrong things they may keep doing it through their entire life. I have heard about some cases where children have been caught copying in exams and parents supported their children by saying lies like their child was practicing on the writing pad or some body else was copying from my child and my thats why my child got caught. Parents shouldn't allow their children to do or try wrong things like smoking, drinking alcohol or any kind of bad activity.
Thus to conclude i would like to say that parents should be strict in some matters with that children and in some matters parents can also behave calmly with their children and explain them what they want.
