And this is up to them, but it is better not to play in front of children. And many parents don't gamble, but they tell or give advice that gambling or slot games are not good, because slot gambling is the most popular. This makes people who are unfamiliar with slot games know about slot games but in a negative way. And this makes parents worry, even makes them the object of ridicule because of its popularity and also makes many people addicted and makes them miserable.
I will ask again, why it is better not to play in front of them? Nobody here can give an explanation without using word "addiction". Well you are no seer. You cant see future. You can predict it. You can do or do not whatever you want in front of a kid, but he will grow up as a firefighter. You never know what your kid will be. You can not live his life and completely decide his future.
But, you can give directions.
Simple examples: eat vegetables in front of kids, when there are candies on the table. Think they will eat them to? When kids watches something on his device or play video games - start vacuum cleaning the house. Think they will join you? Absolutely not. But according to your logic kid will get addicted to vegetables and cleaning.
Kids learn by imitation, anyone that has learned a new language knows how difficult it can be, and kids despite having no previous frame of reference learn how to do it, but how is it done? They listen to you and then imitate the sounds you make, and they do this will all kind of activities as well, so while it is not a sure thing that a kid will learn how to gamble by just watching an adult to do it, the chance is there, and since it is unhealthy for a kid to gamble at such an early age, it is better to hide those activities from them at such an early stage on their development.
Accepted, kids learn by imitating things. Copy/pasting. What we get from that? Parents must behave properly, and kids will copy that. Exactly that idea I am trying to promote here. Explain them what is gambling. That it is for fun only and guess what, like you have said, that will gamble for fun. I am also promoting here that kids are very selective. Why do you even think that they will imitate gambling? They dont imitate 100% what their parents do. If there were like that, they would try to drive a car on their own for example. From media we get only exceptional cases when underaged kid somehow managed to get keys, start car, drive and do something bad. How many cases we get like that among millions of kids, whos parents drive them somewhere daily? Or do you suggest never to drive a car in front if kids, because they will want to drive it also?
