Children learn from the behaviour of adults around them. I remember smoking already smoking some trashed cigarettes because my father was an addicted smoker. What you don't want the younger ones to perform, don't do it before them. In fact, don't even talk about them when these kids are around. I discuss gambling with friends outside the house because I don't want my younger ones to know that I indulge in it. However, teenagers or adolescents should be informed about gambling. This is because they will be exposed to it in school, social media or anywhere else. So these sets of children should be taught about responsible gambling and the consequences of gambling addiction. They should know that gambling is not an option for them now because they have more important things like studies, social skills and others to handle.
