Delivery room drama

Hey guys I'm 28 weeks pregnant with my second baby. When I had my son almost three years ago, my husband was deployed and didn't get to be there for most of my pregnancy and his birth. My mom was in the room with me when I had him and I'm very thankful that she was. Ever since I became pregnant with our daughter, I have only wanted my husband in the room this time around because I never got to experience that with him. My mom has given me a hard time ever since she found that out. She is blaming it on my husband and telling everyone it's his fault that he's putting ideas in my head. She's been acting weird towards me and constantly brings it up and tries making me feel bad. I've tried telling her I have always wanted it to be just my husband this time around and my reasoning behind it but she still keeps trying to blame my husband and giving me guilt trips. Also, my mom is the type of person who craves attention from social media. She goes on Facebook live anytime something is going on. She posts every bit of her life on there and tries making everything about her. That's another reason I don't want her in there. I just don't know what else to say to her. I want that one hour of bonding time with just me, my husband, and our daughter. She got to be there the first time. Is it to much to ask for me to just want it to be him this time?
