Thanks for the honest opinion!
To be honest if I thought
Elizabeth wouldn't degenerate into
Liz, I wouldn't bother with a nn - love the full version. I do like
Ellie, too, but it's a little close to
Allie - and as a teacher I just don't like
Allie or
Beth because of kids I've taught. I tend to agree with you about
Lily - it's better as a stand-alone.
Funny thing is I do call DD wetsy
Betsy when I have to change her!
