It was news to me that 31 states permit underage drinking with a parent:
“You can be 10 years old and drink in Virginia,” said Beth Straeten, a spokeswoman for the state’s Department of Alcoholic Beverage Control.
…Eleven states, Virginia among them, say providing alcohol to an underage son or daughter can only occur in the home. Twenty other states say parents can provide alcohol to their children anywhere.
The Virginia exception was passed during the 2006 legislature. It drew only two negative votes and won the signature of Gov. Timothy M. Kaine.
I was unable to find out what Michigan’s law is. I’ll post an update if anyone fills me in.
[Update: Jess found what appears to be the relevant Michigan law and there does not seem to be any language that would permit a minor to drink with a parent.]
