You're absolutely right about the importance of parental education in guiding children through life's challenges. It's essential to remember that while any addiction can be harmful, gambling itself is intended to be a source of pleasure and entertainment. By fostering a healthy understanding and approach to gambling as to all leisure activities parents can help their children enjoy these activities responsibly and safely.
You need to understand that when they are with their friends, you can no longer see what they're doing unless you have advised them not to do so because that's the important aspect of parenting when you give them important advice. When they are with those who gamble, they also become gamblers no matter how long it takes when they are with those people. Even when playing sports games like how we used to play basketball, they should not engage in betting if you don't want them to get used to it because that's when the problem starts. After all, it opens their craving for other betting games as well.
Of course this is what is worried about, anything can happen that we never even expected before and I think most parents definitely do not want to see their children fall into gambling, No matter if for example the country legalizes gambling activities but if these activities are carried out by children who are still underage then the parents should be able to think rationally that it will be able to threaten their future and also they should be able to think that a child who is still underage then surely they cannot think reasonably and will not be able to consider something rationally to make a decision and what happens is clear that most likely they will only lose a lot of money blindly.
However, it is the duty and obligation of both parents to protect and direct their children to things that are good for themselves and their future, therefore we as parents must really be able to research or identify the possibilities that can be done by a child when they hang out with other people, not that you have to always restrain them but certainly always keep an eye on them so that they are not wrong in associating with the environment.
