Baby shower protocol

This is my first baby and I really wanted to put on my own baby shower with a friend cause we are both designers and had a vision so to speak 😊. Anyways I was talking about it to my mother-in-law and she said I'm not allowed to plan my own baby shower and what of someone has already started planning something for you. Long story short she started to plan something for me and I asked if she talked to my mom at all and she said no.  So I am upset that she isn't including my mom in on the planning and I feel like it's rude.  Am I over reacting/jumping the gun like my husband says?
