I spent a lot of time in Europe visiting grandparents when I was little. We had homemade wine for dinner every night. The kids were allowed to have a few sips if they wanted, but most of us hated it so chose not to have it.
Nobody was ever drunk from drinking wine at dinner time, and now I don't drink at all except for the very occasional glass of wine at a dinner party. I have let my kids have sips of wine and they don't like it. Likewise for cofffee.
When I was in highschool and the other kids said "Let's go drinking!!!" I thought "What's the big deal? I've been doing that all my life. I can go home and have wine tonight if I want to. But I don't want to." My sibling and my cousins who were raised the same way don't drink either.
I think you do more harm by hiding it.
mostly ditto ; I'm a uk citizen and I was brought up with a 'drinking' family - my philosophy is what they see teaches them. You want them to do stuff responsibly, then model that behaviour. That said, I don't smoke. Can't stand the smell, so I suppose that is something they'll have to decide themselves, but that's another discussion.
We have street parties frequently and everyone has children under 10. Everyone bar 1 person drinks, the children all see, but nobody gets slammed, at least not before bedtime, then I've only known 2 people to from the whole street.
Basically, yes, we drink in front of ours and allow smells or 'tastes' of them. Same with coffee and tea.
they're also allowed to sit in the driver's seat when the car is off....
They also play make believe...
moderation in everything, including moderation!
