Naming criteria

I realize for many people, naming is not as much of a struggle. Some people have had this name that they've loved since they were kids and they stick with it throughout the pregnancy and actually use it on their kid. I keep lists of names (as previously mentioned), but as soon as I get pregnant, all of the sudden none of them quite seem like "the" name for baby. Heidi's name was a name that we found in a baby name book about 3/4 of the way through the pregnancy. It wasn't on any of our initial lists. It's starting to look like it will be the same for baby boy.

Things that are important to me for selecting a name:
--I cannot know anyone with that name, especially any kids in the local area. And definitely no one at school (though I'd maybe make an exception if it was a really good kid and a big age difference between my kid and this kid--like there is a Heidi at school now, but she's in high school and a great kid so it doesn't bother me).
--The name has to be easy to spell and easy to pronounce. It has to be an established name (not some kreatyve spelling or made-up recently name). I really don't want my kid to be explaining his name for the rest of his life.
--It has to sound good with our last name, which essentially means no 2-syllable names that end in --er even though I like a lot of those names.
--I'd prefer it's not in the top 100 nationwide or statewide. I think Heidi is in the mid 200's for the year she was born.
--Josh and I both have to love it.

Now you can see why it's been so hard.

Dear baby boy...

Today I am 23 weeks pregnant with you. Did you know 23 is my favorite number? It's my birthday and Daddy's birthday, and the day we started dating all those years ago. And it means that in 17 weeks (or so) I will be holding you in my arms. I'm so ready. I cannot wait to see what you look like, hear what you sound like, feel how heavy you are in my arms. I cannot wait to see your big sister with you and your Daddy with his son. I cannot wait until our family is truly complete. April cannot come soon enough!
Love,
Mama
