But we don't take the same approach to smoking, do we? Or sex? That's what I don't understand. We can educate through talking about things without having to physically introduce them.
I talk to my DD about whatever she wants to talk about, when she wants to talk about, especially as she's now 12 and hitting puberty. I'll be exactly the same with my DS's when they want to talk - and DS1 already talks to me 'secretly' about girls at school.
We've discussed smoking and how bad it is for the body (their Grandad died of lung cancer and my Dad had a cancer scare related to smoking last year, so we've had open doors for all this), and some sex talk from DD.
But I don't see anyone saying 'well, I let them have little drag on my cigarette, it shows I'm relaxed about it, everyone else was having a cigar because it was Christmas, and DD/DS wanted to try a little too'.
And I know that's a daft example, but to me, the alcohol thing is the same. I can have a perfectly rational, calm, relaxed discussion with my dc about alcohol, alcoholism, binge drinking etc, without having to introduce any amounts of alcohol into it.
