We're having a girl!

We had a sonogram done a couple weeks ago and found out that we will be having a baby girl!  We are thrilled that Lexie will have a little sister so close in age.  Now we are working on deciding how to decorate the toddler room for Lexie, and giving the nursery to the baby.  We'll need to move Lexie into a twin bed a couple months before the baby comes, so she won't feel like she's getting kicked out of the crib.  We have told Lexie she's going to have a baby sister, but until she's here, she won't understand what we're meaning.  We have a list of names we will be going through for the baby as well.
