Thanks for all the replies. There is definitely a lot to consider...
At first I would have thought "yes, that name was specific to my first pregnancy;" However, now that I've had some time to accept the loss I really don't think so. We had the name picked out years before I even got pregnant so it wasn't completely specific. ATM I view it almost as people who call their unborn babies peanut, or bean. If that makes any sense.
One of my peeves with western culture is the rigid structure of it. I have great respect for societies that accept (if not encourage) the children to name themselves. With any of my future kids if they choose to change their name later on I will accept that. Granted, I'm on talking "I want my name to be princess kitty sunshine" from a 4 year old... but as a teenager or young adult.
I really enjoyed the post about how in colonial time it was common to name younger siblings after other ones that passed. Maybe I'm selfish and naive but after hearing that it made me think of how we also like the name Alexander. It was my grandpa's name but that doesn't mean I'm replacing him with my (maybe) son.
I'm just kind of thinking out loud here.
