Just wanted to chime in with support for Liztola--I get why she might give her DS a sip or two of wine. In the past when my kids were younger, I wanted them to know that MOST people can enjoy a glass of wine once in awhile, without it turning into a giant drunk fest!
So, for better or for worse, maybe she just was trying to demonstrate a "normal" drinking situation for him? And giving him a sip or two of wine showed him that, while the disease of alcoholism is horrible, the alcohol itself doesn't have the negative power over those who aren't afflicted with it?
Just my idea...
