@AnvilheadII... that's a very thought-provoking question.
Reading back, I don't think I phrased the statement around her parenting well. Regardless of her drinking, I believe she is a great mother, and I completely trust my wife around our child. I know she would never place our child in danger, and I am unaware of any time that she has been drinking around them in an uncontrolled manner (sure, she's had a wine at lunch, etc).
I know if I did not trust her with our child, I would be doing everything I could to protect them.
I honestly don't know how to answer your question yet.
