Avoiding gambling in front of my children or any other teenagers is the most crucial rule I follow. if kids witness us gambling, they can be motivated to do the same. In my opinion. due to their youth and immaturity, it could negatively affect their future. Kids always tends to follow their elders. So I don't want my kids to catch up my bad habits.
As a parent then we are really that responsibility for us to raise them well on the path on which it is really that something to be that good and beneficial to them. As much as possible we shouldnt really be letting them to see and get involved into those things that we are doing specially with gambling. They might be able to encounter it out naturally because of online world or social media but it would be better that you should be avoiding them to see at all cost. If ever it would be that possible then having those simple explaination telling gamblings cons and negative effects
could really be that something will really be helpful to them on later into their own lives or on the time that they become independent.
