Is there any law for filing a case against my mother-in-law?

I am an Indian married to a Spanish originality man in India for the past 1.5 years. Been 11 days, blessed with a beautiful daughter. My mother-in-law who hails from a small town in Spain, with her radical mindset, never liked me from the day one. It was impossible for her to believe that her son married an Indian originality girl than a Spanish one. She would visit home from time to time but would find very difficult to accept me. She started being over-possessive about her son and would make deep-touching comments that I don't feed her son well, that I don't take care of him well, that the needs of the couple and the growing family is never met. Me along with my husband tried discussing with her several times, convincing her that it wasn't true. It was then she started playing games with me. She started putting me down on aspects like my culture, making rude comments on my physique, extremely bad statements on the food I cook or eat, clothes I wear, my education In short, she started making many rude and sometimes difficult to digest comments on anything and everything relating to me. She even started throwing almost everything bought by me, any household , any clothes, thereby trying to change the our lifestyle even if me and my husband are already comfortable with. Now, that our family has expanded with a baby girl being 11 days old, her insecurity and jealousy has increased enormously that she keeps making very creepy personal comments on breastfeeding, about me giving bad education to the baby, that I am not being a nice mother, anything that would emotionally put me so down. She is even trying to create a rift between me and my husband. Last night, she made me feel that I am a worthless mother. I am already on my postpartum recovery phase and any such comments are damaging me emotionally and thereby creating a problem between me and my newborn baby. Please suggest what action can I take against my mentally harassing mother-in-law.
