So in due April 4th.

Whenever I go into labor I don't mind anyone being in the room before baby is born but when its time to push, I don't think I want anyone in there besides my fiancée, my mom wants to be in there so bad but I'm not comfortable and I've told her this and she still says she doesn't care she's gonna be in the room regardless. I mean I hate telling people no especially my mom, but how do I keep that from happening? My fiancée mother hints so hard about being in there and I would only allow her to be in there if my fiancée needs her to comfort him, I don't want anyone to be looking at me giving birth sorry. But idk what to do . . I hate being mean.
