We always let our kids have wine at holidays and when they were 18 we didn’t care if they had a beer when we were at our cottage in the summer. We wanted to get away from it being the “cool” thing to do if they were allowed some social drinking around us as parents. So far it seems to have worked as both kids tell me that they are not big partiers at big party schools. We also have a best friend who has a major pill/alcohol addiction and seeing him at 60 act like an idiot isn’t pleasant. They see how it can turn a person into a shell of their former self and how hard it is to get someone into much needed treatment.
