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?
Here in our country, gambling ads are not allowed on TV, you can only see gambling ads on social media, YouTube, but mostly on social media because of vloggers. It's about your kid, tell him the truth, tell him that gambling is bad for a child, educate him. Your child will understand you, just let him know properly that he is not ready for such things, it is too dangerous for the child. +points for me when the child's parents don't gamble or the child doesn't see his parents gambling, others because they see their parents gambling so the children get curious and try too.
