I have a close friend who took a really pretty timeless name (IMO) and changed it to something quite ordinary when she was about 6 months old. She went through the whole rigramole or getting it properly changed.

It didn't seem to bother the baby but it caused havock for her three year old. The poor boy didn't know what was going on.

Poor thing will always have to fill in that box that says "previous names" and think about what might have been...
