My DH parents spilt up when he was 10 or so. The reason they split was due to FIl partner.So there has always been a bit of friction around this issue. Now that we have DD, I don't know what to call FIL partner, DH says no way to Nanna etc because DD has 2 real nannas already (fair enough) but FIl partner referrs to herself as Nanna when I talk to her on the phone (they live in the country so I dont see them alot) What do I do? and what do I call her that will make everyone happy and not offend anyone? please help
