I know you didn't ask me SPG, but I didn't drink around DD until maybe... this year? I had a drink at my birthday. She's 7. I think it's the only alcoholic drink I've ever had around her.
Why don't I drink around her generally? I really don't know. I just don't feel it's right to drink around her... not until she's older. Again, I'm not exactly sure why and it's not my upbringing... my Dad used to drink beer on the weekends, and Mum would have a glass of red of a night for as long as I can remember.
I do plan on getting off-my-face drunk for one night only in front of her when she's about 16. My mother did that and it was seriously the funniest thing I've ever seen. Kids need to have that crap to bring up at family gatherings... I don't want to deny DD that privilege.
