Amidst news of a new prenatal test that can accurately detect the fetus's sex as early as 7 weeks, USAToday ran this article:

Couples throw "reveal parties" to divulge unborn baby's gender

First, an admission: we chose to know -- and share -- our second child's sex in 1985, when "knowing" was still fairly rare. There were a variety of reasons, ranging from fairly rational (our four-year-old daughter was fairly adamant about her preference for a baby sister) to the truly childish (it really annoyed me that our already-arrogant OB-GYN would know something we didn't). What neither my husband nor I believed was that knowing our baby's sex would tell us much about its personality or abilities. I was a tomboy who had truly expected to grow up to be a cowboy; he was a talented pianist with a degree in theater. Moreover, I had already been studying gender and sexuality for nearly a decade, and had a pretty good understanding of the complexities of gender identity. So I don't believe that everyone who throws a reveal party is essentializing their unborn child or longing for a return to the Mad Men era.

But I wonder. When all you know is your child's sex, based on a test that reports it only as either M or F, what do you actually know? Consider:

  • some babies are born with ambiguous genitalia, which may or may not agree with the test results 
  • knowing an individual's sex predicts nearly nothing about them as individuals 
  • sex is not gender is not sexual orientation 

I am pretty sure I would still be inclined to "find out" if I were pregnant today. After all, I was the sneaky kid who ferreted out the hidden Christmas presents and carefully unwrapped (and re-wrapped) them. I'd probably share the news with friends and family. I might even throw a "reveal party", because I LOVE parties. But I would still let my son be a person first and foremost.

 
 
According to recent research, 41% of expectant parents are choosing not to find out the sex of their baby before it's born. Many of those who do would prefer to have it both ways: keep the surprise but also get gender-specific gifts for their offspring. A Texas entrepreneur has solved the problem with an online gift registry that caters to these "NFO" parents. This video explains how it works.

I am finding in my research that planning and purchasing is one of the top reasons for finding out the baby's sex in advance. Of course, the question remains: why does having the right pink or blue wardrobe matter so much, at 20 weeks or 40?
 
 
Over the last 25 years, baby clothes have become increasingly gendered, and neutral options have nearly vanished. Certainly one reason is the technology that allows us to know a baby's sex with nearly 100% certainty long before birth. As a costume historian, my interest is not only in what people choose to do with that information, but how they react to the choice itself. I am hearing from more and more expectant parents who choose NOT to know; not surprisingly, these are also the folks who are the most vocal about the lack of neutral styles and about stereotypical gender binary design. They not only want to wait until birth to know if they are having a son or a daughter, but even then they want to avoid pink, girly things and "little man" outfits.

At the other extreme are parents who embrace early sex identification, because it makes preparations (not only clothing, but nursery designs and naming)  more convenient, or because they feel it helps them connect with the baby as a "real" person. For these folks, there is an industry eager to provide the information they crave. I was tipped off to the existence of First Glimpse by references and recommendations in several pregnancy blogs. This is more than the sonograms once used primarily to detect potential problems, which could sometimes also detect genetalia. What was incidental is now central, in First Glimpse's "Gender Determination" packages. Combining elements of medicine, spa treatments, scrapbooking and glamor photography, they offer women a pregnancy experience that is as commodified as a cruise. Maybe that's next.
