It's a....

GIRL! We are so excited and everything looks healthy!

Here's the conversation with Addi and Karter:

Me: Guess what! We found out what the baby is and it's a girl!!

Karter: Nooooooo

Addi: (nothing)

Me: Addi, you're going to have a baby sister!

Addi: Oh, yay!!!

Addi really is very excited. She has said all along that it's a baby sister. Last week she carried a baby doll everywhere and said it was her baby sister. We are so happy to know what it is and that everything was healthy. And no we have no names at this point. All we have been thinking of is boy names, so we will have to switch gears!
