Your problem is that your question has been answered but you refuse to accept the answer. I don't question your motives or concerns for this baby, but the system doessn't work the way you think it should, and you can't seem to get around that. Let me repeat my earlier best answer to your concern;

"your neice will have the baby and you will place a call to DSS to report child neglect, an investigation will occur, there will be a finding of fault and the baby will be placed in foster care.

That's the system at work and it's the best you can do with it.
