i am so sorry! was there any type of formalized custody order for your parents to have him? if so i'd call your caseworker tonight, leaving a message about this, do you have witnesses to that the baby was happy and healthy with you, like close responsible neighbors, your minister, the peditrician who can speak to your high quality care of him, and to his good health with you, any individual that a court would find to be credible. don't talk to her or her friends, as tempting as it would be don't engage with them at all, no matter what. you all have to be above reproach and as pure as fresh snow. make sure the yard and home is immaculate, take photos to prove it. an experienced family law attorney is going to cost money, there is no way around that. stephanies history will catch up with her. i am so sorry that this has happened to him and you.
