My 15yr old DD (16 in Nov) is upset with me just now because I won't let her go to a friend's house party next month where DD has said she would drink alcohol. She's tried alcohol previously, e.g. a few sips of champagne at special events or a taste of her dad's beer at home but there is only one parent supervising at the party and we have different parenting styles and I think at 15 DD is too young to potentially get drunk, something which she is hinting at. DH says I need to trust her and I do trust her - I trust her to be a teen! I did not have a healthy relationship with alcohol from around the age of 16-19 (fuelling my concerns) and I'm a bit confused as to why people think it's ok for a 15yr old to be allowed into that environment without parental supervision, albeit there WILL be a parent there, just not one of us. Am I being a mean mum and spoiling DD's fun? I genuinely don't feel it appropriate that 15yr olds should be intoxicated and as she begins college next year there will be plenty time for partying with new friends then. This is causing heat at home because DD normally makes her own choices, usually very well but this is an issue. My main concern is if she does become intoxicated she will therefore be vulnerable. The general consensus is that I'm being too controlling of her and I don't want to be but I feel I have to look out for her best interests too.
AIBU?
