Am I wrong to be mad about this?!? (BIRTH PLAN)

My mother in law is very persistent about wanting to be in the room when I give birth. I have a birth plan and REALLY want to stick to it as much as we can. Somethings we won’t have total control over. But this we do. When I had my first daughter 3 years ago, I let her and my mom in the room. She was trying to take control over everything and was driving me nuts. Which made the entire experience 10x worse. Do I have a right to get mad at my husband for this? Or am I over reacting with my pregnant attitude 🤣
