i dont think any gambler will intentionally want their kid to see them doing it. kids learn so fast and when they see their parent doing it they also want to try. its good to take caution and be very careful sometimes these kids might be watching their parents without them knowing and then they go to start practising behind them. one thing about children is that the like to practise what they see and if they see it constantly, it gives them confidence to want to try it.
