That is true. Since the parents should be the models to their children, they shouldn’t be watching TV too, but instead be with the children to teach and guide them in their homework.

They should see to it that they will study their lessons. Allow them to watch TV only on Saturdays. Sunday morning and afternoon, they can also be allowed. However in the evening no more. They have to prepare their school bags and do their homework.

Better still on Friday night, they should do their homeworks, so by Sunday night they can just study.

@Dina is right, we only allowed to watch the T.V after finishing our homework or even during Friday night and weekend is better.
My kids only able to watch T.V when they are at their granny’s house, we have no T.V at home, but computer is another kind of T.V too nowadays.

My kids love to watch the Youtube or some videos clips at the social media too, but always restricted by us.

And, we always mention the computer is belong to me, not them, so they can simply manipulate it or doing something on it. They do alert on this.

We allocate 2 hours cartoon watching time every week for them to watch some cartoon at Youtube.

And, they have ice cream section on Monday but provided have a nail cut first. This help us to set up a life rhythm of the kids, so they won’t have much argument when we urge them to do something as per scheduled.
