My son hated it. I could see it in his eyes the older he got & the more he could understand. He even went so far ask to ask me to not drink some evenings. It breaks my heart to think about it now. He's 13 now & he's very proud of his sober mom. There's no better feeling.
Someone posted this not to long ago. It's heartbreaking & chilling but effective. It's the way I felt every time my dad drank. When I'm completely honest with myself, it's probably the way my son felt too.
