Birth mom waiting to make decision

I was recently contacted by my cousin who is expecting. She is due in about 3 weeks. She has spent most of her pregnancy in complete denial. She only recently told her son who is a preteen, that she was even pregnant. She has been to the doctor once at the beginning to confirm pregnancy and only recently began to see a doctor. She has told us that if she decides to place her baby through adoption that we would be her choice. She wanted time to consider it. Her living circumstances are such that raising a 2nd child would be difficult. She has no job, little support from family and is currently sharing a bedroom with her son as she lives with friends. The father is not involved and she just barely told her parents and siblings that she is pregnant. Her family seems to be encouraging her to raise her child and I don't really know if she has even told them that she is considering placing her child with us. She is only communicating to me through written messages and has asked for time to decide. Do i just continue to wait in the hope that she may decide after the babies born? Or do I try to put it out of my head? We have received spiritual promptings that the Lord wants us to adopt this child but that its mother still has her agency to choose. How do you hang on through the waiting? How do you cope with very little information coming your way from the mom or her family?
