Wife not coming back home after delivery

I am 33 yrs old and my wife is 25 from Pune. Im Govt Servant. Im married for 3 yrs. During marriage life, there were small fights & issues between us but we loved each other also. But my wife used to tell everything about our relation and household things to her mother. My mother in law used to fight us that my daughter is not capable of doing household work. You should keep a maid otherwise my mother should also do household work. My mother in-law frequently said that I should speak from my wife's side everytime instead of my mother's side. There were lot of fights on this issue. Then my wife was pregnant about a year ago. I was giving proper treatment as needed. But Doctor never suggested her for bed rest. But she again faught with my mother over house hold works. My mother in llaw faught with us over household work and told us to give her complete bed rest. Then after three months of pregnancy, on my wife's birthday her parents came for Birthday but before birthday they again started fighting with us and provoked my wife against us and said we will take our daughter to their home because she needs bed rest. There was huge fight on this issue on the Birthday. After mediation and saying that we will send wife in 7th month as per rituals, they went their house. But my egoistic parents in law kept provoking my wife against us on phone and kept intimidating that we will see them when she comes to their house for delivery. But before sending for delivery, my wife assured me that I will come in 2 months after delivery and not to worry as we were emotionally connected because our baby was coming. I trusted her and she went. But after going to her parental house in bijapur for delivery my wife again started fighting on small issues & after my daughter born on 13th November, My wife started ignoring our phone calls. She was not coming on the phone or video calls and my mother in law was telling that she very ill that she could not talk on the phone. They didn't not even showed my daughter on videos call. Then after one month I went to their house and saw that my daughter was not fed well and she was malnourished. Her weight was reduced to 2 kg from 2.5 kg. They again blamed me & my mother for this that we gave my wife tension and she got depressed. My daughter was admitted in ICU because of malnutrition. Then I asked my wife to come to our home to Pune. She said I will not come until you don't leave your mother. Because of my mother and relatives I fight with my wife, she said. I asked my wife to sort out things with mediation but she is not even ready for mediation for 5-6 months saying health and mental issues. My parents in law have provoked and completely brainwashed her against me and my mother. Her parents said they won't send her daughter because she was tortured and torment in our house. Now what can I do because of this iam frustrated and I feel harrassed. There is no police or legal complaint filed from me or my wife's side till now.
