Most long-distance daughters choose a check-in time by what fits their week. You finish work at six, so you call at six-thirty. That is a good time for a conversation. It may be a poor time for checking, because by six-thirty she may have eaten alone at noon, sat in one chair since breakfast, or gone a whole afternoon without a word from anyone in the house.
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.
Sizing a check-in means starting from her house, not your calendar. Before you pick a time, sketch her ordinary day in blocks: when she gets up, when she eats, when she bathes, when anyone else comes through the door, and where the longest empty stretch falls.
Find the stretch that is actually empty
Ask her to walk you through a normal Tuesday, not a good day she is saving for your visit. Listen for the gaps. A neighbor who drops by at ten, a pharmacy run on Thursdays, a friend who calls at lunch: those hours are covered. The hours with nothing in them are where a fall, a missed meal, or a confused afternoon would go unnoticed the longest.
Then compare two timings honestly. A morning call catches the night that just ended: did she sleep, did she get up, is she steady on her feet. An evening call catches the whole day: did she eat, did she go out, did anything go wrong. Neither is the right answer everywhere. Pick the one that falls closest to her longest empty stretch, and keep the questions short enough that a tired parent can answer them.
Know what a call cannot see
A phone call will not show you a fall on the bathroom floor or a stove left on. If the longest empty stretch is also the hardest one, the call is only half of the plan. Someone who can look in during that stretch, even briefly, covers what your voice cannot. This is where local help in St. Louis matters more than the schedule itself.
Keep the call fixed. Ask the same three questions each time: what did you eat today, did you leave the house, is there anything you need before tomorrow. A change in her answers tells you more than a long, cheerful conversation.
Tonight
Write down her three longest stretches alone, with the days of the week when they happen. Choose one for a fixed call and tell her you will call at that time every day, so a missed answer means something to both of you. Put her neighbor's name, the nearest person with a key, and the emergency number on one sheet, taped inside a kitchen cupboard where you can read it over the phone.
What to leave with the doctor
Bring the hours she is alone, not only her symptoms. Ask whether her balance, memory, sleep, or appetite changes which hours are safe for her to be on her own, and whether anything she has noticed should change how often someone checks in. Ask which signs mean she needs a call to the office the same day. The doctor can answer those questions. A phone schedule cannot.
