Where do I begin... my son just turned six and his biological father will be back from the vacation with bars on the wall in Dec 2013... he has never seen him, nor is his name on the birth certificate... I'm terrified of the unknown when he gets released... he was imprisoned in another state... but I'd like to know if he is ever able to try to waltz into my son's life at his leisure... is there anything I can do to stop this from EVER happening?
