So my mother and I have a toxic relationship.  We aren't close and never have been, I didn't live with her growing up and could care less if she was a part of my life. She is controlling where she has no right to be and that makes me not want to even discuss my life with her. I have a 6 years old son and am currently pregnant with my daughter due in November. She and my son will have different fathers. My sons father hasn't been in the picture for nearly 4 years and my daughters father has been great in picking up that role for him. My mother essentially thinks he has no right to discipline my son and that he is over stepping "her boundaries" when it comes to us. My son loves her so that is the only reason she is still around. She is constantly going against my rules and requests when he is over her house. IE bedtime routines, night time potty training, and even answering the phone when I call. She is rude and disrespectful to my daughters father and he doesn't want my mother in her life and I don't blame him. Now my mother is constantly threatening to take us to court to establish visitation bc she has "grandparent rights". This happens even if I don't let her take my son whe verb she wants. I think once a month is good enough. These are my children and I am tired of her interference. I don't know what to do, does she even have any grand to stand on?
