Working on list for dc3 very early! (Just had dc2). Anyhow, love Charmaine and Diana is after my Mum, Diane, who died when I was 13. Charmaine is pronounced Shar-main, btw. I also quite like Charmian (pn Car-mian).
Since Charmin' have now rebranded I don't care about that objection!
My two children are Imogen Sophia and Arthur Henry - does Charmaine work as a sib?
