Sometimes the answer to a night plan is no, and it stays no. She may not want a person in the house after dark, or a device on her wrist, or a rail on the wall. A refusal is her right and it deserves a real hearing. The harder part is noticing when a no is slowly taking apart the plan that was supposed to protect the route, because nobody says it out loud.

Signs the plan is slipping
Watch the small things along the trip. The night light she used to keep on is now off. A grab point or rail is no longer used, or has been moved out of reach. The walker or chair that was meant to stay by the bed is parked somewhere else. She takes the trip in the dark when she used to use the light. She stops mentioning the night at all, or says she is fine in a way that closes the subject. Any one of these can be ordinary. Several together, over a stretch of nights, mean the route is no longer being used the way it was set up.
What to do when you see it
Name the specific stop where the sign appears, rather than the whole plan. Offer one choice that she can accept, such as a light she controls herself, rather than a rule she has to follow. Let her choose the form of help where you can, because a choice she made is more likely to hold than one imposed on her. If a sign suggests her steadiness or thinking has changed, that is a question for her doctor, not something to settle by yourself at night. Bring the sign list to the appointment so the clinical side can see what changed and when.
What to write down
Keep a short running list with three columns: the sign you saw, the stop it touches, and the response you chose. Write what she said in her own words if she said something useful, without making it a quote for anyone else. Review the list each week, and mark which signs have come back. A pattern of repeated signs at the same stop is the early warning you can act on before the next fall.
