Name didn't fit your baby

Has anyone ever picked a name for your baby and then when you saw him or her for the first time, it just didn't fit them?? I'm so worried we are going to pick a name and then it won't fit our baby when it gets here. I know weird fear but naming my children is one of my favorite and most feared part of having babies! If you changed your child's name at birth, what name did you have picked out and what name did you use?
