My sister is 4 months pregnant and isn't married to the child's Father. They had a rough break-up so now he is threatening to take the child from her not matter what. She is 21 and still lives at home with our parents, doesn't have a job, and isn't going to school. However, she wants this baby more than anything. He is a scumbag, working at a fast food restaurant and has drug problems that haven't been documented. Does anyone have any advice on what she needs to do to try and get custody of the child? Please help.
