We want the gender of our baby to be a surprise, so we're trying to come up with bother girl and boy names. We've settled on a boy name, but a girl name has been impossible. We literally sat there staring blankly at each other. Our daughter is named Coraline so I was hoping to find something to go nice with that and our last name is Mallegni (muh-leg-nee) my husband likes Addison, but a girl I went to school with named her baby that I don't want to be a copy cat.
