In the labor room...

Just wondering if I'm being totally ridiculous not wanting my mother in law in the delivery room when I give birth? She wasn't in the room with our first baby because I didn't want anyone but my mom and husband. Me and my mother in law are not close at all so I don't know why she is pushing my husband to let her in this time. He doesn't get it and says it's unfair my mom can be in but not her. I actually feel she's just trying to annoy me. I just don't know why either of them don't get it.
