I think gender reveal parties are mostly women's ideas. I have yet to meet a man expecting a baby that wanted a gender reveal party. I've been to a few and on all occasions, we ended up in a group of men away from the crowd including the father-to-be questioning why all this time and money is being spent on it.
Maybe the pyrotechnics, fire, and alligators are just the only way that women can get men to spend money on such an event?
I mean, I get having a party for your child. Hell, we had our daughter Baptised mostly because we thought it was a good excuse to have a party with friends and family and let everyone meet her, but I don't get the big productions for the actual gender reveal.
