Good question and I am trying to think.......

Phone conversations/messages......yes.

Emails (not often).....yes

In session..........not that I can remember.....but i think I'd love it, I am going to be on the lookout for if/when she does.

I often use ppls names when talking with them. So, I think that some do it and some don't (people that is). I find it as an engagement tool to connect and make sure we are really "there" together. I use her name in session tho.
