Truth be told, I'm weirded out when my dad refers to Lily as my daughter and he does it a lot. I really don't think he's trying to be funny - I think he's serious. He'll say things like your daughter wants to go to bed or should I feed your daughter? Or he'll be talking to her and say go ask your mother if you can have a treat. This may sound strange but, in a way, it actually kind of makes me feel bad.
