So for my first pregnancy, my mom and my boyfriend were in the room with me while I gave birth. I didn't really feel comfortable with my mom in there, but I was like why not, she's my mom and this is my first baby. But for this one, I don't want her in there with me and I don't want to be rude or hurt her feelings. I need help on how to go about telling her this.
