I'm sure it can be difficult to parent a teen with an alcoholic parent in part because the alcoholic parent is going to be more inattentive and therefore lenient. As an ACOA I know what this kind of parenting got me: No boundaries. Not to mention no discipline or routine in my life. Anyway, you'll probably want to be more strict but will need to find a healthy balance. Maybe there is a book on coparenting with an alcoholic?
