Playing gambling in front of children is the same as teaching children to gamble because children are good imitators. So stop gambling in front of you because the impact will be very big on his education. Gambling is something that is not good, even for adults gambling can have bad consequences, especially for children, of course their minds are not smart enough to see the negative impacts of gambling.
Impact on education - playing blackjack might teach them to count to 21 quickly
Kids are imitators, but they dont imitate everything parents do. If they were complete imitators, parents would never punish then for misbehave. Or we would have little 7yo adults. Ever imagined how people in countryside live? What they do with pigs, sheeps, cows or chicken when they are hungry? Strange that we dont have little maniacs that see adult kill animals for food.
Anyway, show me an example of any kid who is addicted to gamble. But not use gambling as just a method to get some easy money.
