yeah i also gamble with my mother and with my relatives too but just at home. I never experienced gambling with them in a casino and i dont think its appropriate to gamble with my parents in such place. Although i did gamble in a casino with my cousins and siblings already.
At a certain point in their life every child will probably gamble with their parents but they see that as a way of having fun and enjoying those moments. I'm talking about a simple gamble here for example the child says do you wanna bet with me that I am going to win this game. That kind of gambling is alright as long as it doesn't turn into something obsessive and it's not being played on real money.
