I like Nell the best - the only thing I'm worried about with that one is if she should grow up to be a little plump & have "thoughtful" children singing Nelly The Elephant at her. I am also expecting a little girl so have been thinking of possible problems with names too
.
I don't like Nina - sorry, too "harsh" sounding for me. Nadia is OK, not as nice as Nell but better than Nina.
