Dd is going to her first 'proper' party this weekend. There will certainly be booze, and weed I imagine. She is a sensible kid and going with a sensible friend. I'm sure she will have a drink. We've talked about safety and what's reasonable/ok. It occurred to me that, as she hasn't drunk before, she won't know what a normal, versus an insanely strong, drink is. So should I prepare her a normal, I don't know, vodka and coke to have a few sips of the day before? How do others handle this stage?
