People in the delivery room...

AD
Ok ladies help me out. This isnt my first go around. With my 2 oldest i had my mother in the room. With my 2nd son she said it was taking too long amd left and went home only to barge in the room right as soon as baby was born. She went off. Slamming the door,telling me she wont let me see my other 2 kids because she was leaving the hospital etc. She had me crying on a day im supposed to be happy. Now im expecting as is my sister. Well with my sister she isnt including my mom in anything, she is having our deceased step moms family do most the stuff for her although my mom asked to throw a baby shower for her. So her is my problem. My mom is excited for me to have mine and im 100% sure she is planning on being in the delivery room. However Im not sure I want her in there. I want me and daddy amd i think i just want it personal. I have no problem with her coming in after but im not sure about during the pushing part. How do i address this without her going off and making me feel like shit? She becomes juvenile when she is mad. (Oh all im good for is to watch kids) (i know itd be better if i was dead) etc. She really goes off the end. She had a problem with baby dad cutting our first kids umbilical cord. Like wtf. When i was pregnant with my oldest i did his nursery came home and she completely redid it all saying she liked it better that way. I moved out after i had him at 17. I couldnt do it no more. Please help.
