The system has treated your sister and her new family terribly, and it's been so frustrating to read about -- I can't imagine what it was like to live with it! I'm so glad to hear that everything has been resolved now, and that your sister and BIL can feel confident that their family is secure with them.

The transition to working at home must be so strange! I can definitely see that there would be good bits -- but I agree, it's terribly exciting to see someone outside of the usual circle!
