If you are sleeping with a baby monitor on so you can hear your mother at night, you are not alone, and you are not doing it wrong. Plenty of families in west St. Louis County start exactly here after the second or third fall. The plain answer to the question you typed is this: a monitor can wake you, but it cannot walk Mom to the bathroom. If she is falling on the trip from the bed to the toilet, what matters is whether anyone can reach her before she stands. Size your nights by that, not by whether the monitor is on.
Local option: New Plan Care gives families in the St. Louis area in-home help so a parent can stay home: companionship, help with bathing and dressing, meals, and overnight care. Call (314) 405-0887.
This piece helps you tell whether the monitor still fits your household, and what to do when it does not.
What the monitor actually does
A monitor carries a sound or a picture from her room to yours. That is all. It does not slow her down, does not turn on a light, does not steady her at the doorway. It works when two things are true: you wake at the first sound, and you can cover the distance from your bed to hers before she is on her feet.
What it costs: The Missouri median for non-medical in-home care is $33 an hour, per the CareScout (Genworth) Cost of Care Survey 2025 state data tables, released March 2026. New Plan Care's standard rate is $34 an hour with a four-hour minimum, so a visit starts at $136 (newplancare.com/services).
Both of those are worth testing honestly. You may live in the same house, down the hall. You may be across the house, or upstairs, or sleeping on her couch two nights a week and at home the rest. Each of those is a different household, and the monitor fits each one differently.
A three-night check
For the next three nights, keep a note pad by your side of the monitor. Each time it wakes you, write:
The time. What you heard first: the bed creaking, her voice, her feet, the walker. Where she was when you got to her: still lying down, sitting on the edge, standing, already in the hall. How long it took you to get there. Which of the six stops on her route was the hard one that trip: the bed edge, the first step, the doorway, the hall, the bathroom door, the toilet.
In the morning, also write how you feel. Not as a judgment. Just whether you slept between calls, and whether you were steady on your own feet when you got up.
After three nights, read it back. If you reached her lying down or sitting most times, the monitor is doing its job for now. If you keep arriving after she is already standing or walking, the monitor is telling you something it cannot fix: there is a gap between the sound and your arrival, and that gap is where the falls live.
Signs the monitor no longer fits
You find her standing, or in the hall, more than once. You sleep through a trip and learn about it in the morning. She has started getting up more times than she used to. You are up so often that you are tired and unsteady yourself on the stairs or in the dark hall. You have stopped sleeping in your own bed. You work in the morning and cannot keep the nights going. Any one of these is enough to start looking at overnight help. Two or more, and the nights have outgrown what one person with a monitor can cover.
Questions about why she wakes so often, or why she is unsteady when she does, go to her physician. Bring the three-night note.
What overnight help looks like in this house
A non-medical overnight caregiver takes the place of the monitor and of the run down the hall. They stay in or near her room. When she stirs, they are already there: the light goes on, the walker is in reach, her footwear is on, and someone is beside her before she stands. They walk the six stops with her, wait or help in the bathroom as she prefers, settle her back into bed and write down the time and how it went. They can give a medication reminder if one falls overnight, while the medicine itself stays with you, her doctor and her pharmacist. If she falls, they call you and, when needed, emergency services.
Ask for an awake overnight shift if your notes show she is up more than once or twice, or if she is standing before anyone could reach her. A sleeping arrangement only fits a night where she rarely wakes and the caregiver can still get to her in time.
You can also start small. Some families begin with two or three nights a week, so the person who has been listening to the monitor can sleep in a bed with the door closed and the monitor off.
How to start
Take your three-night note and call two or three agencies that serve your part of the county. Read them the times and the stops. Ask whether they offer awake overnight shifts, the minimum shift length, whether the same person will come each night, and what happens if the caregiver cannot come. Ask for an in-home visit, and walk the person along her full route from bed to toilet.
