I agree with you, nowadays children are introduced to online gambling through such attractive advertisements. Due to the ease of gambling, children can easily access these casinos. And children are easily attracted to online casinos, and become addicted. Therefore, if parents are giving a device to their children, the parents should limit there children's internet usage. And keep an eye on every activity of internet usage. Overall, All parents must be extremely aware and it is important to monitor the online activities of their children.
They can see the attractive advertisement about gambling but they don't think that is a gambling. They just attract to follow the advertisements and clicking the link on that thing and visit the casino. If there are no understanding from the children how to use their devices properly, they will attract to gambling without they realize and if no one will know what they do, they can get addicted to gambling. Parents must control their children using their devices and always remind them about the danger of using the internet without control. Yes, parents must always monitor the online activities of their children so their children can use internet with right.
If children who understand the issue of money, especially those who can transact money, see such advertisements or links and click on those links and enter those casino sites, then I think this will be one of the reasons for their addiction. There are many children who do not understand the need for money, so they are less likely to get addicted quickly.
Parents must have proper knowledge about their children. Otherwise, they can get off the track at any time. Since it is not difficult to access online casinos, a child can get addicted quickly, which is not unusual. If parents take enough care of their children, then it will not be difficult to recover from those situations.
