A gender reveal party is a party held during pregnancy to reveal the gender of the baby to future parents, family and friends. Prenatal gender determination technology provides the necessary information. This practice originated in the United States in the late 2000s.
This is distinct from, but sometimes combined with, a baby shower, where the main activity is giving gifts to expecting parents for their unborn baby. A gender reveal party often includes gender stereotypes, such as pink and blue, denoting girls and boys, respectively.
The practice has been controversial and criticized for its use of complex and dangerous special effects that directly contributed to many deaths, injuries, and large-scale wildfires, including the Eldorado fire. The practice has also been criticized for reinforcing gender stereotypes and binary gender essentialism.
