I wanted to convey my message here that gambling in front of our kids may put adverse effects on their growing minds and they may also take the wrong path and start gambling (either by asking you personally for funds or by stealing it in order to fulfill their gambling cravings).
I'm sharing this because I saw this issue with my kiddo who was once watching me gamble at a website playing blackjack and she started asking me more about the game. Then one day, she wanted to play it herself and asked me if she can go for it and I said "no, it's not your legal age to go for such games". So, it's better to keep our kiddos away from gambling and let them focus on their studies, else it'd actually ruin everything for the whole family if the kid takes the wrong path.
This is a very correct idea, because children always copy the behavior and activities of their parents, and only then they understand the meaning of what they are doing. In fact, they rely entirely on their parents' activities, adopting them, and do not know whether they are doing something good or something bad now.
Therefore, it is better to refrain from gambling of any kind with children, it is too early for them to deal with such money and such strong emotions.
Why refrain, if the best option would be to talk, show, teach and make them understand, if you say they dont know what gambling is? Important, I advice to do that not prepare them for gambling, but to prepare for future life and consequences.
I find it hard to understand why parents always choose easy mode called ban, prohibition, taboo? Instead of teaching, spending time, checking if kids understand. You have mentioned money. Then its parents duty to earn more, so kid wont have an idea to earn now (they will have plenty of work when they grow up) to help parents. You have mentioned strong emotions - parents should warn kids about that, give examples, try to substitute them with emotions they could get from elsewhere.
Parents easily destroy kids vision of life with a little word "NO". Hard to understand when you do something, but if kid wants to do it also or ask about it and parents just say NO. Easy to say NO. Hard to explain and wait till kid understand your point agrees to that.
