Mother in law madness

Hi, does anyone else have a monster in law? Honestly, seems like she has gotten worse since i’ve given birth. She is really such an evil person. Didn’t even congratulate us but expects to be able to come to the house and hold our baby. I want to restrict her from seeing him but i can’t since she is my husband’s mom. Even my husband is getting fed up with her crazy attitude. I just have such terrible anxiety every time she holds my baby. It would be different if she were nice to me. I’ve seriously resented her since i gave birth. She has been the main trigger to my postpartum baby blues/anxiety/depression
