I did NOT want to know with DS. I wasn't even sure I wanted an u/s, but we did decide to have that. I told everyone I met in the office that day, "We don't want to know. Don't tell us the sex!"
Actually, DH *did* want to know, but I wouldn't let them tell him either. My uterus, my perogative.
And people do act like you are weird. :P to them! They also want to know what names you've picked out, and I wouldn't share those either, unless they were already discarded from our list. We went to the hospital with a list of about 5 girls' names and 7 boys' names. I needed to meet my son before I could name him.
But this time I am less sure I will do this. Hmm...
First of all, the week before the u/s visit, I told DS in utero (repeatedly) that we were going to be peeking at him, and he should cover himself if he didn't want anyone to see anything. I felt like he deserved to know what was coming and prepare himself.
So I ended up feeling so strongly that I could communicate with my unborn child that it didn't seem like as much of an intrusion as I was worried it would be.
So if we do an u/s this time, and if I tell this little babe about it ahead of time so s/he can decide whether to show off or keep it private, maybe I will find out.
(It might just be that I have a stronger gender preference this time due to already having a son and hoping I will have a daughter, too. Still, I mostly think I am just feeling more relaxed about the intrusion. We'll see...)
