Many families size home help by picking a number of hours that sounds reasonable and hoping it fits. A better starting point is the household itself: who is home, which rooms your parent actually uses each day, and when your parent is alone. Those answers show where the gaps are, and the gaps tell you how much help is worth scheduling and at what times.

Map the day, not the week
Draw your parent's ordinary day in four blocks: morning, midday, afternoon, and evening. Mark what happens in each block, such as breakfast, a walk, a phone call from a sibling, a regular outing, meals, television, and bedtime. Then mark who is in the house or nearby during each block. The empty blocks are the candidates for help. Avoid planning around the week as a single total, because a few hours on Tuesday and a few hours on Saturday can leave every evening untouched.
Name the household type
A parent who lives alone usually needs company and a steady check on meals and errands at predictable times, so the gaps tend to be in the evenings and on weekends. A parent who shares a home with an adult child who works away from the house all day usually needs help covering the hours when nobody is home, plus any household tasks the child cannot keep up with. A parent who lives apart from the family, perhaps across a county line, usually needs a helper who can keep a steady routine without the family present, which makes the notebook and a clear written task list matter more.
Count the gaps against the rooms in use
Walk through the rooms your parent uses in an ordinary day. If the helper will spend the visit in the kitchen and living area, the visit plan can focus there. Use home safety, room by room to decide which rooms are in regular use and what each one contains, then size visits to match. A visit covering meals and company in the main living area is a different length from one that also includes laundry and tasks spread across the house. Let the rooms and tasks set the visit length, not the other way around.
Leave room for the family's share
Not every gap should go to a helper. Some things are better kept by the family, such as a standing phone call, a weekly family meal, or a visit that is simply about being present. Name these first. That way the helper's hours are reserved for the tasks that really need another pair of hands, and the family's time is protected rather than squeezed out.
Test the fit against one ordinary week
Before committing to a full schedule, sketch one ordinary week with the proposed visits in place. Look for conflicts: visits that overlap with family visits, long stretches that your parent will feel as lonely, and tasks scheduled on days when your parent already has an outing. Then ask the agency to walk through the same week and tell you where they would add or move a visit. Their answer will show whether they understand the household or are simply filling time slots.
Local logistics that change the size
Travel time across the City of St. Louis, St. Louis County, St. Charles County, or the Illinois side of the region changes how long a visit really is. A helper who must drive a long way each direction loses part of a short visit to the road. Ask whether travel is counted in the booked time, and how the agency handles a home that sits on a different side of the region from its office. Those answers can change the schedule you finally choose.
