Narcissists mother

sarah

Me and my husband have a two year old together and during this pandemic we have stopped my mother from seeing our child because she doesnt stay home and she goes out in public when ever she feels like it and doesnt wear a mask ... but now she is wanting to see our daughter and when we tell her no the threatens to call the cops or child protective services .... even threaten to take us to court for grandparents rights here in georgia and me and my husband is fed up with her actions is there anything we can do to stop this from happening ? Or how would you handle the situation
