DH and I are Mummy and Daddy, not our own names, around DS. A habit that will stop when he is at school - mostly because PiL call each other Mother and Father still and no, I'm not having that! I wouldn't mind DS calling us by our names TBH, so long as it was done respectfully. But as other people are Aunty/Uncle/Mr/Mrs/Miss [first name] it may sound a bit odd.

I wil say it annoys me when my mother calls my father by his name in conversation with me, but my mother's brother and uncle have the same name so I have to ask to which one she is referring! But that's the only reason I still refer to him as Dad, just to ease confusion. And now he's "the Grandad" not Dad anyway.
