Or should it be Casper? Hubby has thrown this in at the last minute and I think I like it - would be Cass for most of the time I think. Is it masculine? Is it cool? Does it suit a grown man? Is it nicer than Nathaniel (currently agreed upon name)?
NB - Cassius is not an option. I can't get my head around the meaning. Plus my older son is called Jude and Jo Wiley has sons called Jude and Cassius - she is not someone I want people to think I am trying to emulate!
