Gender reveal drama

Kaisha
I'm getting irritated because my mother doesn't want to know the gender of the baby. My SO and I want to know. We want to be sure to have a pink or blue baby shower so we get things other than green and yellow neutral colors. It wouldn't be so bad if my mother didn't want to be so involved in the pregnancy and the baby shower. She insists on a gender neutral shower just so she doesn't have to know.  I feel like I'm just going to have to be firm and tell her that we want to know and want our friends and family to know therefore she can come to a regular shower or stay home. Is this being selfish? Is there any compromise we can come to?
