While watching TV with my kid, I've watched various advertisements of gambling nature (let's say for example, Rummy123, RummyCircle, A23 Rummy, etc.)
These are all specifically Indian ads, but I'm sure you may have seen various gambling advertisements, some banners at boundaries when cricket is ongoing, even in any other sport. How would a kid ignore those things, they might just come and ask you about what is it. Till when can we lie to them? Don't you think that the frequency of such ads must be less in order to let the kids not get trapped into gambling and don't do it at such a small age?
Actually, it happening also others region not only with yours. But what we can do if this gambling advertisement games on TV channel and if your children sitting in front of that then I think you should change the channel immediately. Or if they ask about that what was that then there is a no need to tell them lie tell them the truth, tell them gambling was not a good thing for kids, show them the bad sides of gambling and tell them you can also gamble after 18 age with your ability.
