Thanks everyone for the nice comments!

Jackie - thanks for posting the meaning - it's one of the things I LOVE about the name - I was looking for a less-common name, but not something " weird", so I think it fits the bill!!

Jen - re the whole nickname / shortening thing - realistically people WILL shorten the name, so I would rather have her known as Calli than Cals or something less attractive. Also, as she gets older, cute girlie names sometimes become less appropriate (especially for example in the workplace), so she has a choice to use her given name or her shortened form of the name.

(For example my Son Cameron - he often gets called CAM by his friends, when he was small we called him Cammie, but one day when he is a business professional he has the option of a formal, strong-sounding name).
