The truth is I don't know what to call you right now, because I might call you name that may look offensive to you, but that's by the way. Talking about your daughter, the gambling habit she have developed at her tender age is an inappropriate behaviour, which I don't do away with such behaviour, normally gambling is not a bad thing, but starting to gambler at a tender age when the person is not up to 18 make the person look indecent, especially when the person is a female. In my country if a female child demonstrate this kind of inappropriate behaviour she will automatically get tag of an indecent person, and no man will take her serious when it comes to relationship and so on.
And I think everyone would probably consider it wrong to let a girl gamble before the age of 18. A father with gambling experience should not let that happen, he certainly understands the negative impacts of gambling at too young an age. When a child is grown and has their own income, we would consider it normal, but at 17, it's considered bad. It must be admitted that it's not easy to be a responsible father in all aspects, but try to ensure your children don't gamble at too young an age, when their main focus should be shaping their future.
