Is it even possible to decline my work's baby shower?

I work in a small corporate office and we celebrate birthdays and things, including baby showers. I don't want a baby shower thrown for me for the sake of being consistent by my co-workers who complained about me, and my family and friends are both planning two already; this would also be a bit superfluous.

Our gender neutral monster-themed baby shower

My husband and I knew that a traditional baby shower wouldn't be for us, and we were thrilled when my mother-in-law offered to throw us a shower and asked what theme and colors we wanted. From home-made plush favors and invitations to cakes baked in jars we knew we were going to have the perfect monster mash bash to celebrate our own little monster!
