I love Charlotte ( I have a DS though and another DS on the way so it's not an option for me)

IMHO - If you love it - I would use it...lock it in before your DH changes his mind..

My DH and I like Kai or Kye as our 2nd DS's name. DH has a cousin called Jye and my cousin is Kylie but has always been known as Ky and she has a son called Tyson and he gets called Ty lol but it's not stopping me and no one has mentioned it when we told them we liked Kye
