I am not sure where to start. My nephew lives in Virginia with his mother, my sister. She is a convicted felon, HIV positive, and a drug addict. She left my nephew with a neighbor last week and said she would "be right back" and she didn't return. The next day, the neighbor called the police and DHS. My sister finally returned after threats that they would take her 4 year old away. My nephew is back with her. The father has never been in the picture. My husband and I would like to give my nephew a proper home and we are able to do that emotionally and financially. However, we live in Iowa. We have told my sister that we would raise her son. However, we are highly skeptical that she will do this without being forced. I am not sure what the next step is. Any advice would be greatly appreciated. We are very concerned about my nephew's future.
