If you like a name but not the nicknames

[Blahblahgingerbreadlady]

Do you just get over it or just try and change the nicknames or pick a different name?

for example I like Clementine but really can’t stand clem or clemmy. I like Elowen but there are so many Ellie’s in my current child’s life! Would you just decide to go with other names because if this?

This. You can until they are old enough to decide for themselves. Clementine may love the full name, and insist on it all the time, but she might decide to be Clem or Clemmie at some point.
