Here's an article about a couple who is trying to do just that. Personally, I think it's going to be a wasted effort on their part. I think gender is not something we "choose," and being born a particular sex and being the opposite gender (or neither gender) is something that happens no matter how much society treats the child like the gender they are perceiving them to be based on their sex. Therefore, I'm inclined to think treating them neutrally isn't going to give the child any more of an ability to choose it for themselves. I don't even think the kid's going to be confused, other than maybe over language that they hear other people using, and wondering why it doesn't apply to them. I think the kid's going to figure out all by themselves, like everyone else does, and that will be that.
I also think that it's not that hard to develop whatever talents a child has, without worrying about them being restricted by gender. I think the world will be a much more progressive place when both girls and boys are taught that they can do anything, and that they can embrace their gender at the same time. So, I kinda thing from that perspective they are barking up the wrong tree, as well.
