As a role model though, you should show that you are someone they should look up to. Being a gambler is not bad of course, but it does not really set a good example.
This is true, we should set an example to our kids and we must be the role model for them. There are good and bad results for exposing your kid early in gambling industry.
Even if you gamble pretty low amounts, the fact is that it could lead to you child thinking that it is alright to gamble. He may grow up to be someone who gets exposed to gambling early and result to him being addicted to it.
This is one of the bad result that I'm saying.
You are correct that there is a chance they do not turn into an addicted gambler, but still you cannot discount the fact that there is a chance he can get addicted to it. It is better to uphold an image that you do not gamble so when the child grows up, he will think to himself that his dad/mom did not gamble so why should I?
I'll set an example, my father is a drunkard but to tell you the fact, I didn't grew up as a drunkard. This is why I've said that there are kids that aren't affected even they have a gambling parents.
I cannot dictate any parent on what to do, because it is their sole decision what to do with their kids but it is something I morally feel to be right to tell parents.
Right again, they are all big and they know what's best for their kids.
I commend you for not following you father's foot steps, you are a great example to the kids if they know that their grandfather was a drunkard but not their father. I do agree that every person, even your own flesh and blood, will have a different tendencies in getting addicted or not into whatever like gambling, drinking, or, worse, drugs. But the best thing for a parent would probably still be guidance.
I, for one, have tried drugs and I am not too proud of it and regret doing it. I was young and the peer pressure was hard, but when I did try it I did not get addicted and, believe it or not, I did not enjoy it. Probably thanks to the inner voice I hear. I hear my parents talking in my head telling me it is bad to take drugs. Well and good, I never did it again.
