Touchdown! Greaser!
Incredibly wishful thinking and I doubt that makes a difference what so ever. One of the worst drinkers I know came from a house with no alcohol.While my heart goes out to the OP, I have to wonder. Do they drink? Is there booze in the house? If a child grows up around drinkers, is it any surprise that the child will also drink? My parents never drank. There was never alcohol in the house. Same with my wife. As a consequence, we never drank and there is no alcohol in our house. The consequence of that is that none of our children drink and they will never end up like the OP's child.
I think one is by far better off to be a good example of what responsible alcohol consumption consists of and realize that if a child wants to drink before they are 21 they will do so. The best think you can do is hope the responsible consumption they always saw will be remembered and make sure the child knows they can always call you for a ride without terrible consequences.
Just my opinion. FWIW I was raised around major alcohol abuse and as a result of that I absolutely did not touch alcohol. I did start to drink once I turned 21, tried to use some common sense to avoid trouble.
I was always afraid that if I drank I would become that which I saw the pain of my entire childhood (alcoholism). I took me a long time to realize that I'm my own person and I can control what I do. I've never been addicted to anything and have always been able to stop anything. That didn't change with alcohol.
