It's almost impossible to ensure limited exposure because children under 18 can always have the right to ask and search in any topic.
Children do not hesitate to ask similar questions about topics that society still considers embarrassing and even dangerous, such as the topic of sex or the interpretation of what is happening in wars. Gambling is also a reality that exists and there is no escape from the child being exposed to signals from here and there, even unintentionally. Therefore, it is important for the parents to be aware and able to provide cognitive support through good formulation of answers according to the cognitive and psychological abilities of the child.
