I think you should do what the case worker tells you to do and document the effort. If there is no actual case, then I would not make the extra effort. I would make the mother prove interest in her child...or not...and take steps to obtain legal custody of the child. My nephew found out the hard way that with no CO, he has only as much "right" as his child's mother allows. If you keep her, you should make it official.
