My sister has a 15 year long meth addiction plus alcohol problems. She also has some undiagnosed mental illness issues. She has a history of homelessness and being in jail due to drugs and disorderly public conduct. She is 2 weeks away from her due date. I have already contacted CPS in California, we are in Ilinois. Hopefully, CPS will check out her living situation when the baby arrives. There is a father involved, but I don't know that he wants to raise a child long term. My husband and I would like to adopt the child, so that he isn't lost to the family. My husband has a good job and I work part time, a nice home, three children of our own and live in help. What are our chances?
