Just had a massive fight with my mum

I expressed to my mother that I only want my partner to be there during the birth. She insists on being there and says I am being selfish and unreasonable because I want to have people come and visit the next day rather than the day of the birth so I can have some time to rest and bond with my baby. I am a shy and introverted person and I worry that having lots of people there will freak me out and stall my labour. My mum says that our parents (her, my dad, MIL and FIL) have a right to be there. Am I being unreasonable? How should I deal with this? I'm sad that I've upset my mum. UPDATE: Put my foot down and said she wasn't to come until after the birth when I have rested. She told me that she was going to be there whether I like it or not 😐
