I've been wondering lately about how some adults refer to themselves in the third person by using their name or relationship to the child to identify them selves in interactions with the child.
Eg: a Nanna says to her grandchild " Nanna wants to read you a book"
Eg: The child's father says " daddy will miss you today".
I'm wondering if anyone can help me out with the history of using the third person in interactions with children.

I'm also curious if its a conscious decision to follow this practice or if you've decided to refer to yourself in the first person (I, me etc) and why.
Mmm... Pondering....
I hope that makes sense!
