Dear Amy: My daughter and son-in-law allow their 17-year-old son to drink alcohol in their home — and not just a sip of wine. They believe that he will become normalized to drinking and not consider it “forbidden fruit” when he goes away to college. Since there is a history of alcoholism in our family, I’m not convinced this is wise. Am I wrong? — Concerned Grandma Dear Grandma: I’m wondering why any parent would want their teen to become normalized to drinking. Surely these parents don’t imagine that their son will enter the binge-drinking atmosphere of the typical college campus limiting his own excess due to the sophistication he’s acquired by being a social drinker at home. (“Sorry, Delta Tau Chi brothers, I’ll pass on that kegger as I slowly sip my fine Merlot.”) If these parents drink at home with their son, that’s their business.
