Should We Find Out The Sex Of The Baby?

Right. So this is not a "tell us what to do!" post because I'm 99% sure we've made our decision but I'm really interested to hear what you did and if you'd do it differently if given a do-over.  

Here in BC, in a typical, uncomplicated pregnancy, a woman has a dating ultrasound around eight weeks and another ultrasound at 20 weeks. After the 20-week ultrasound, the parents are given the option of finding out the sex of the baby. (Side note: I haven't reached the "advanced maternal age" milestone so my knowledge is of pregnancy in women under the age of 35.) 

Shawn and I were on the same page while pregnant with Grady. As soon as we found out we were pregnant we decided to find out the sex. And we didn't regret our decision. 

This time around, my initial instinct was to wait for a delivery room surprise. This pregnancy (which we are 99.5% sure is our last) has been so closely monitored and we know so much about it, not finding out the sex held a certain appeal. Meanwhile Shawn 100% wanted to find out the sex. We were at an impasse. 

Now, if I had Very Strong Feelings about not finding out the sex, I wouldn't find out the sex. And if Shawn had Very Strong Feelings about finding out the sex, he would find out the sex. And we would make it work somehow. But neither of us felt particularly adamant about our preference.  

So we used Grady as our tiebreaker. Before we even found out we were expecting, Grady told us his sister was coming. When we were far enough along in the pregnancy to feel comfortable sharing the news with Grady, he was adamant that he was getting a baby sister. He refuses to entertain the thought of potentially getting a baby brother. Which is a bit odd, to be honest, but we think it's because his newest cousin is a girl so in his mind, baby siblings are girl babies. I don't know. All I know is that if I'm pregnant with Grady's little brother, we need to start easing him into it now. (And I'm not going to lie, finding out the sex and being able to reduce the baby name fights-I-mean-discussions by 50% is massively appealing to me. Let's just say that Shawn and my baby name preferences are on opposite sides of the spectrum.)

Did you find out the sex of your baby in advance or was it a delivery room surprise? Would you do it differently next time?
