To begin with I'm 100% against Gender Reveal Parties. Not a fan, because every couple is trying to one up the other couple based off social media posts.
It's all a competition in my mind. So much money spent on it as well.
Not only that, this particular way seems very unappetizing. I think of the different colored ketchup's that came out back in the day and how that just didn't seem to go over well.
