Husband and I are going through divorce...how do I get my daughter back asap!?!?

My husband and I are splitting up for the second time. He is physically abusive and suffers from alcoholism. He was planning on moving his stuff out today. The only problem is that he went to my sitters house and took our 2 years old little girl! He is in no way responsible enough to care for her by himself. The only time her entire life she was left alone with him over night he left her at home alone and went to a bar and was pulled over going over 100mph drunk driving. I am concerned and think that it is in her best interest to come back home where she always has been until we go to court for custody,. I plan on going to the courthouse as soon as they open to file for divorce, full custody, and possibly a restraining order. Just 2 weeks ago he punched me in my lip with our daughter standing there watching the whole thing....She has never been away from me a full day....What do I do?!?!?!
