AITAH for kicking the mother out of the delivery room?

Me 34 f and my husband 35 M have two children one 14 year old and one 3 year old.a few months ago my BIL and his wife found out that they could not have kids so my BIL ask for me to be there surrogate I agreed because my BIL is family and we grew up together and he has always wanted kids. I made it clear to my husband at the start that I was only doing this for my BIL because his wife has always been rude and always trying to one up me and we did not have the best relationship. But when I was 7 months pregnant with there kid we started talking about birth plans and that is when the drama started. BILs wife told me I would be giving birth in a nud!st community with no pain meds or anything and she said that it was part of her "religion" but me my husband and BIL shut that down really fast we decided on a hospital birth with my husband,BIL and His wife in the room the last 2 months of the pregnancy she was sulking around crying saying that we do not respect her because she can not carry a child.so one day when I was 9 months pregnant my BIL called me saying that maybe I should consider having my baby in a nud!st colony because his wife has been crying about it for weeks. Me and my husband shut that down and told them that I'm giving birth in a hospital and that's that. Fast forward to when I give birth. My husband drives me to the hospital and calls my BIL and his wife they get to the hospital when we do. But a few minutes before I give birth I was in pain I have birth to 2 baby's before this and it could not compare to the pain. When I would show signs of pain like crying or groaning she would scoff or say a snarky remark. The last straw was when I was about to push and she told me "Don't scream....or else" every single person in the room looked at her and the nurse kicked her out. My BIL did not care about his wife geting kicked out he fist wanted to see his baby be born. A few hours after I gave birth me and my husband were talking and he said that I was a bit harsh to kick BILs wife out because she is the mother. So AITAH?
