Boy that is a tough one. Judges typically have no sympathy towards parents who give up their rights and then decide they don't want to any longer, but this is a different case because of the jail time, etc. First, she needs to research the laws on what that means and what recourse, if any there is to take. The best thing of course is to call an attorney. Most will even give you advice on the phone or let you know if they even think it's a worthy cause and what all would be involved. Does she speak with the ex-husband/father of the child? If so, she might want to start with him and see if he would be willing to give some visits. She needs to understand that this will be emotionally trying on the child and if she wants to be in the childs life, she can't walk out again. It will be a long legal battle if the father wants to fight it I am sure of that. Best of luck and hope it all works out for the best. I think it is important, when in the childs best interest, that they are reunited with their birth parents. Even adopted children who have the best homes and loving care givers constantly wonder about their bio parents, where they came from, what they look like, etc. so it is certainly worth pursuing.
