Addilyn spelling rethink 😭

Nina • 26, Married, Mother to 4 daughters!

My husband's name is Addison and as our last child we've decided on Addilyn. His nn is Addi. But I don't want hers to be too. So now I'm second guessing but he's set. I like Addalyn with the nn Adda. But he says it defeats the purpose 😭. I'm named after my aunt, we are still known as "Big Nina and Little Nina" or I'm called Nina Marie. I don't want to call out Addi and both answer. Bleh hormones.
