The real advice is that the time for good advice is long past. In situations like this a person can only dig themselves deeper for so long, but eventually will face some of the downside consequences for their actions - even if those actions were necessary at the time. An excellent way for her to end up in jail and her baby with someone else is to commit fraud at the hospital. Healthcare fraud could also potentially endanger both her AND the child should their be complications because it puts the healthcare providers in the position of having lacking (or worse, fabricated or inaccurate) medical history available to guide their decisions. There ARE ways to handle many of the problems that have gotten her to this point, but running and planning to commit fraud are not among the ones that are going to give her a rosey outcome.
She needs to call the number you were given and start getting some help to CHANGE and FIX some of the situation, including legally getting the guardianship issue addressed. No one expects her to be able to do it by herself, but she's got to get things RIGHT because the avenues for her to continue to run are about to evaporate quickly now that there's a child on the way.
