Overbearing mother

I’m keeping this anonymous just in case someone I know sees it. But growing up my mom was emotionally abusive so we didn’t have the best relationship. I am 19 and moved out a week after I turned 18. When I found out I was pregnant We waited 12 weeks to tell our families due to the risk of something happening. Well starting from then on my mom has been nothing but overbearing. She constantly tells me she’s upset because I didn’t tell her first. She keeps insisting she will call my daughter by a different name (she wants her to have a different middle name) and she keeps talking about how she can’t wait to kiss her and hold her. Don’t get me wrong I understand this is her first grandchild but it gets worse. Recently my SO and I decided we would keep our little one at home for 6 weeks at least before she meets anyone due to the virus. His family and most of my family are perfectly ok with that and understand. But my mom won’t let me hear the end of it. “Covid isn’t real” and “you’re doctor is stupid, I’m her grandmother she needs to see me before that” are the responses I got after I told her. She then went on to say if anyone else met my daughter before she did she would be pissed and would practically lose her sh*t. Throughout my pregnancy she constantly wound touch my stomach even after I told her to stop and I was uncomfortable with that (multiple people told me to let her do it and I that I should expect it since I’m pregnant) but I have anxiety issues and for someone who has belittled me because of how my body looked I didn’t appreciate her doing that. She constantly makes comments about how my daughter will love her and she will be staying the night at her house. I don’t know I know this is a long post but it all makes me extremely uncomfortable and at this point I’ve tried everything. She made the comment she will come see her before the 6 weeks (like show up at my house unannounced) and that she will be calling/ FaceTiming everyday. I understand being excited but when will it end? When will people stop enabling her actions by telling me to deal with it because I’m having her first grandchild?
