I think it is a great idea. The paperwork I saw and had to fill out would really help in some circumstances. Not only to inform them, but also to empower them so they are prepared to know how to best handle some situations. I had to write down things that I thought they should say to me. Things that would anger me or escalate the situation. When to recognize what stage I was in, and how to handle the different stages (example: ignore it, validate it, get professional help). Feeling some sense of knowledge and feeling equipped to handle unexpected changes will make it easier for you all. I think it sounds like you are handling this very responsibly.
