I have Arlo And Ari (Arianna) they are only a year apart so I wanted them a bit similar🙃no matter which names you choose you’ll mix them up eventually. I still get called autumn my little sisters name lol
Even though the spelling makes it look like a totally different name, there's literally just one phonetic that's different. If I'm honest, I personally wouldn't fancy having a name that similar to my sibling; it would make me feel less of an individual.
Ivy or Annie or Elizabeth or Kaylin
Mila? It’s similar to Myla but the pronunciation isn’t as close to Micah.
Wb Amina
Malia is similar but not more different to Micah. It’s in my list so thought I’d share. Go with what you love.
I think it’s going to be more confusing for you to keep the names straight! Both very pretty names and if you like them go for it!
