So much of the journey to get pregnant, and then the pregnancy itself, is private. There might have been months or years of trying to conceive, interventions like IVF, miscarriages, tears and struggle few will ever know.
Once pregnant, perhaps there were months of debilitating morning sickness and exhaustion. In consideration for all that parents go through—all the excitement and struggle that exist behind the scenes—it's perfectly understandable that when it comes time to share the news, many parents are enthusiastic about celebrating publicly, from the pregnancy announcement to the labor and birth.
"The core of the gender reveal is about having a communal, familial spirit around this moment," said Carly Gieseler, an assistant professor in the Department of Performing and Fine Arts at York College CUNY and author of Gender Reveal Parties: Performing community identity in pink and blue. A gender reveal party has become an opportunity to gather family and friends to celebrate with both parents—whereas the traditional baby shower has typically been thrown for mom with mostly women present.
Jaclyn Siegel, a postdoctoral research scholar in the Body Image, Sexuality, and Health Lab at San Diego State University, likens the desire to celebrate the sex to the early stages of relationships, in which you want to mark every milestone, including your 6-week and 3-month "anniversaries." It's a totally normal urge, wanting to celebrate every milestone of a pregnancy, too.
Social media ups the ante for festivities. Because gender reveal parties have adopted these visual stunts—Pink smoke! Blue confetti! Pink parachute billowing out of a dad's skydiving backpack!—it stokes a very common desire to attract positive attention on social media.
Neuroscientists have shown "likes" and other forms of positive feedback on social platforms trigger a release of dopamine in our brain—the same kind of chemical reaction you might get from recreational drugs, sex and gambling. In the middle of a pregnancy, when parents are tired and anxious and dealing with all kinds of side effects, it's no wonder they crave some social media love before the baby arrives.
