Keeping parent away from their grandchild

KD

There are many reasons why I don’t want my child around my mom. She has always put herself first, even when it meant that my siblings and I were in an unhealthy and bad situation for many years. There are a long list of reasons why I do not trust her to be a good influence on my child. I’m still pregnant and she doesn’t know yet. I know that it is going to be an insane battle when I do tell her. It’s not that I’m saying she can never see my child it’s that I want her to prove to me that I can trust her. I also know that where I live, she can take hubby and I to court for visitation rights. Without disclosing what went on for many years with her knowledge, as mean as if may be for me to say, I know that is what I will use if she decides to take us to court. Was wondering if anyone else has gone through something similar?
