I love [name]Amelia[/name], [name]Anne[/name], and [name]Audrey[/name]! [name]Avigail[/name] is interesting, and better than [name]Abigail[/name], which I find boring. I’ve never heard of [name]Amma[/name], but I like [name]Alma[/name]. I really like [name]Ava[/name] but it’s so popular… I think [name]Avi[/name] is a boy’s name. [name]April[/name] seems dated, and Adiya might get pronunciation problems. [name]Addyson[/name] is just awful.
Good luck!
Really love Adiya!
[name]Abigail[/name] [name]Rae[/name]–I like [name]Abigail[/name], mostly because of [name]Abigail[/name] [name]Adams[/name], but it is so popular I would save it for a mn. Or at least use a less common mn than [name]Rae[/name]…
[name]Addyson[/name] nn [name]Addy[/name]–no. Definite no. Invented, trashy, and tryndee. [name]Will[/name] be dated in about five years and people will wonder what they were thinking.
Adiya nn [name]Addy[/name]–Good, what about [name]Adina[/name] nn [name]Addie[/name]?
[name]Amelia[/name] nn [name]Mel[/name]–nice. I worry about its popularity, though I think it’s substantial enough so that that doesn’t matter.
[name]Amma[/name] nn [name]Ammie[/name]–would be constantly confused with the megapopular [name]Emma[/name]. [name]Ammie[/name] would be confused with [name]Amy[/name], [name]Emmie[/name], [name]Annie[/name] and so on…
[name]Anne[/name] nn [name]Annie[/name]–I love [name]Annie[/name], what about using [name]Annika[/name], [name]Annabel[/name], or [name]Anneliese[/name] to get the nickname?
[name]April[/name]–nice, a little bit dated but in a good way
[name]Audrey[/name]–nice but it is getting pretty popular…maybe a mn?
[name]Ava[/name]–sorry, too trendy 
what about [name]Adelaide[/name], [name]Adeline[/name], [name]Avalon[/name], or [name]Ada[/name]?
[name]Avi[/name]–I like it as a nickname, for a name like [name]Aviva[/name] or [name]Avis[/name]. What about [name]Ariana[/name] nn [name]Ari[/name]?
[name]Avigail[/name]–nice but it would cause tons of pronounciation problems, and always be confused with [name]Abigail[/name].
Good luck!
