Changing baby's name...?

Samantha
Have you ever changed your baby's name while pregnant? Or added a second middle name?  
This may sound nuts, but I had a dream last night and I swear it was my daughter speaking to me. She said a name and I immediately woke up with this overwhelming feeling that it needed to be part of her name. I honestly had never even heard the name and had to look it up. Turns out it's a very beautiful name with very symbolic meaning to me. My husband thinks adding a second middle name "doesn't go together" and doesn't want to change her name either. I'm only 24 weeks right now, so it's not like we've gotten anything with her name or initials yet.
