I grew up in Italian-canadian households, so even as a little kid I got diluted wine at meals. As a teen I thought it was illegal so didn’t talk about it, then one day had a hotel room tossed by narcs who left empty handed yet left all the beer in the tub that we were obviously all drinking… only one of us was drinking age, and the room was in their name, so the narcs never even commented on it. In your home, in B.C. anyway, you have discretion about what the kids consume, as long as it isn’t abuse.
