My fiance and I are thinking about trying to gain custody of our nephew. He is currently living with my mother and has been since he was born almost 5 years ago. My sister has popped in and out of his life and its just not fair to him. I also do not agree with the way he is being raised and my mother still allows my sister to make all the rules and decisions for him. I just want my nephew to be happy and not yanked around anymore. I have spent one day sometimes more a week with him since he was born and since we purchased our house last September he has stayed with us every weekend. He has everything he needs at my home, his own room clothes, toys and food. What should we do?
