I voted for Carter. I love coming up with nicknames, and didn't even think of Carter the Farter!! It thought of Carter Puterschmidt from Family Guy (Lois' Dad), and the character Noah Wyle played in ER - he was a Carter wasn't he?

But i think it is definately the better of the two names, IMO.

And we know a guy whose surname is Lane, and for as long as I've known him (14 years now), he has been known as Laney. Not a problem for him, or for anyone who knows him, but if you are telling a story about him to someone else, and mention his name, they all immediately think we are talking about a girl.

And people might think of Laine Beachley too, making them thenk of a girl.

In the end it doesn't really matter about the boy/girl name thing though. Our DD's name is actually an old boy's name, but just isn't common for boys, so when people ask us about her name, and we tell them it is a boys name, they don't really believe us, and reckon it is a pretty girls name

Good luck with deciding which one to go with!
