Seeking Visitation Rights with Baby

What rights do I have? My ex-girlfriend and I had a baby in September. We are no longer together,but I want to have a relationship with my daughter I do not get along with her parents and the only way she will let me see her is if I go to her parents house and visit her, she wont let me pick up the baby. It is very uncomfortable and very hard to establish a relationship. Her parents got her an attorney and had me served with papers to agree to giving her full custody and limited visitation with them supervising it! I have 24days to respond and I dont know what to do,or what course of action I should take. Please Help. Thank You.
