Did you contact a center for abused women and let your daughter talk to them?
I don't know what she's going to do about the baby, but he is the father so supposedly he has a right to visit and create more trouble.

It is a blessing that your daughter is fed up enough with this guy not to want him around, but i'm afraid trouble can be only postponed.

If your daughter really want to be out of this nightmare, she's got to learn how to protect her heart, ber baby and her person from this man. This is a path, that she has to learn.

Best luck to you
