Delivery room list

La
The hospital where I am having my baby only allows five people in the delivery room. Once you make the list and submit it, you can't change it. I'm only 8 weeks (9 tomorrow) but I'm worried about how my MIL will handle the news that she's probably not going to be on that list. All I want is my husband, mom, and maybe my sister in there. My MIL is crazy jealous of my mother, and I know it's probably going to kill her but I'm the one who is going to be spread eagle, and I don't want people I'm not that close to witnessing that. I'm also worried it's going to make my husband angry that I don't want her in there, but that I DO want MY mom in there. Help?
