I don't let my kids have a sip of coke let alone alcohol. I know they are young now but I don't plan on changing my views.
When they ask they are told no as it's a grown ups drink, it's not for children.

Tanya good on you for having the guts to give your daughter firm boundaries. I wasn't, took advantage of my parents apathetic nature, drank to excess and almost choked on my vomit one night. I was lucky that was the worst that happened to me. I lost a few hours of my life and that terrified the hell out of me.
After that night I spent most parties being a mother hen and holding my girlfriends hair while they vomited and consoling one girl who had been raped and bashed. I also saw a 15 year old boy punch out a car window because some guy looked at him the wrong way supposedly.
