Does this change once the kids are over 18 and are fully adults, except they can’t legally drink alcohol? None of them are minors (under 18). Is the choice theirs to grab a beer vs a soda? Their parents don’t really have control over a 19 or 20 year old. I did a bit of googling and it is not clear to me. There comes a point when most of the kids friends are over 21, but a few are not. Is a parent required to card all the kids or ask their birthday?
This is some champagne at midnight not shots for hours on end. I can’t imagine anyone, even a parent, being upset at a midnight toast. I would certainly have sparkling cider and not make the assumption that all of the kids drink and avoid pre-midnight alcohol. However, I don’t see much liability in a glass of champagne for 19 to 20 yos that are sleeping over. And I was very strict about all this with my own kids and their friends.
