My teen DSC have recently started calling DH by his first name. He doesn't like it and much prefers being called Dad (and has told them so) but they still do it.
I know some kids address their parents by their first nameswhich is obviously fine for them but it doesn't sound "right" to me (or DH) but I'm not really sure why! And yes we know that if this is all DH has to worry about then he's doing ok 
But leaving the triviality of this issue aside I'm curious as to what others think, and any ideas as to how DH should address this his DC?
