Just interested in who is finding out the sex of their unborn child and who isn't and what your reasoning is.
I am not (DC3) as I believe there are so few surprises left in life so would prefer not to know. My sister has 2 DC's and found out beforehand for both of them (1DD and 1DS). She thinks I'm pre-historic for not wanting to know, saying that the technology is there so why not use it? But then she is somewhat of a control freak! 
I didn't find out with my other two, but I suppose now having one of each it doesn't matter one way or the other. Perhaps if I had 2DD's or 2DS's it may change how I feel.
I am interested to find out how others view it.
