Alcoholic watching baby?


I just got into an argument with my fiancé because I told him I would never let his grandmother watch our daughter alone. He told me that she doesn’t drink when she’s watching kids and how she used to watch him. I don’t care who kids she babysits I don’t trust her around my kid period! She’s a hardcore alcoholic. He told me I was being judgmental and I told him he was bias because that’s his family. If my dad was an alcoholic I would feel the same way. Family or not it’s about the well being of the child. He’s so mad but I don’t care.
