I voted for Micah because all of your older kid's names end in the a sound, you even picked Ava as your girl name, which I too love by the way. I do like Jeremiah, but don't really like Jeremy, and my cousin has a Jeremiah, and the kids shortened it to Jeremy. Micah is great and sounds perfect with the older kid's names. Do you like Noah, Zachariah, or Ezra?
Yes, I agree with you, I'm having difficulty with what my boys' names might be shortened too. Love Jeremiah, do NOT like Jeremy or Jerry (Just too Jerry Springer for me!!). Love Micah, but would just die if his name got shortened to 'Mike' (my step-father is called 'Mike' and is just a horrible, horrid man). Love Levi, but do not like 'Lee' as a nickname. Don't mind 'Ash' for Asher but my husband doesn't like that nickname. And for Roman..don't like 'Rom' (know someone called this). Soooooooo, I guess with any name we choose we will just need to be consistent in using his full name ALL the time so no-one dares shorten it!! Noah is not allowed...an ex-boyfriend of mine is called Noah. Zachariah is cool but I have a nephew called Zachary so it's a little too close. And Ezra just sounds a little too feminine for me. But thanks so much for your input, I appreciate it!!!
