Looking back at my side of the family and my grandparents, they were too tight to drink, but definitely had the alcoholic personality and I was told that their parents were very physically and verbally abusive.
My husband's side would be the oak tree of alcoholism. It reaches back to Ireland, about 5 generations.
So my question to be added would be: Who was the acorn?
I did worry that my son would be an alcoholic. And he is. But recovering 14 months. Don't worry and don't panic. Educate yourself and your children.
