How did you deal with being bombarded at the hospital after birth?

I'm going to give birth soon and all I can think about is how my MIL is going to be. She's the type who gets her feeling hurts waaaay too easily over the smallest things and on top of that she's controlling as heck. I just know that as soon as my LO comes she's going to be right there in the room and most likely not let me hold her for a while and I don't mean to sound selfish but I grew her in my body for 9 months and felt her little kicks and just want to be alone for her first few moments into the world. I want to be able to hold her first and not have to constantly ask "can I please have my baby back I want to hold her". I know I won't have this problem with my mom because she can take things and not get upset if I ask her to let me have my first moments with my baby girl. I'm stuck here. I don't want to offend her
