Whos going to be in your room?

Ba
I originally wanted my mom and SO I really wanted my mom in there for medical support in case there was a csection which is likely what will happen. If any decisions for me had to be made I wanted her to make them. But now I want 2 Or more hours alone with the baby and my SO to do skin to skin and for it to latch before people flood in. Would it be rude for me to ask my mom to step out once it was actually time for the baby to make its way out? Or is it normal for the extra person to leave when pushing or surgery starts?
