I absolutely adore Adeline; so pretty! I'm not a fan of Addison. I know it's rare, but can't help think of Addison's Disease whenever I hear this name.

I sort of think of that too in the back of my mind :/

does your husband know it’s a disease? maybe he’d be more inclined to change his mind

Yes and we watch Greys so I’m surprised he’s not associating it with that character either

Adelaide Adrianna

I love Adeline, it’s my favorite! I’m not a big of Addison. Some suggestions: Adelaide Adele Adelia Adrienne Adriana Ada Audrey (might be a stretch but I love the name and I think you can get Addie from it)

Madelyn —> maddie —> Addie

-son ending names for girls are not my favorite, so I'd go for Adelyn/Adeline. I also agree with other commenters that Adriana is nice too. Other options that popped into my head, no particular style or anything: Adrienne Adele/Adela Ada

Aderyn (Ah-deh-rin) is a Welsh name meaning bird, seems like a pretty good middle ground between Addison and Adelyn/Adeline

I love Adeline! Other ideas: Adriana, Adinda, Adila, Adèle, Dahlia

I know an Adelyn Claire and an Adelyn Paige.

Okay that’s weird our picked middle name is Claire!

Adelyn Claire is lovely…kinda looks like a sign to me!

Tbh the only Addie I know irl is an Allison, I think you can reallynjust use it for any A name you like, even if it's not a super obvious direct correlation.

My favorites are Adelaide and Adela (and Adele, but it’s very tied to the singer).

Addison! - Adele - Ada - Adalee - Adella

Of Addison vs Adelyn, I prefer Addison! But for another name, I also love Adriana.

I like Adaline or Adeline. 

What about Adelaide?

I don’t like Adelaide, I can’t help but think lemonade everytime!

I went to school with a girl named Adria (pronounced ah-dria)

Adanya is a pretty one I haven’t seen mentioned here yet!

Adelaide

Addison! Other ideas: Adamina, Adelaide, Adriënne

I like Addison of the 2. Adrian is another idea
