Child Custody

My wife is not staying together with me for more than 6 months. I wanted to meet my daughter who is 3 years old, I asked her to give child for atleast 2 days in a week. but my wife is not allowing to bring my child at my home. My wife has also started working from last 2 months and staying with her widow mother and younger sister.. She is 12 hrs working and keeping my child with her mother, my mother in law (MIL) health is also not good, but my daughter is staying with her and with her neighbours. Wife hardly gives time to my daughter, but because of her Ego she is wasting my child life and not giving it to me. I am well settled staying in mumbai and I have my parents who loves my child a lot and can take care of my daughter very well. Me and parents are very much depressed and do not understand what steps we need to take. I can take care of my child without her support and hence do not want to give her any maintainence. Morover my daughter loves me a lot and when she sees me and my parents, she leaves my wife and runs behind us. she is forcefully being kept their. In my case what options are there to get custody of my child, my daughters age is 3 yrs? Do father do not have any rights to bring child home for few days? Child is forcefully kept, do we have any law for this? If there is any option available, I want to hire a lawyer in mumbai who can give 100% results for child custody. Awaiting for positive responses Thank You
