Many families arrange home help because one relative already carries most of the daily work. In that case the hired hours fill gaps, not the whole week. Sizing starts with a written list of the helper's fixed commitments, and only then with a count of the hours that are still open.

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.

Write the helper's week as a grid

Draw seven rows for the days and five columns for the blocks: early morning, midday, afternoon, evening, and overnight. In each cell write one of three marks: family covers it, another relative covers it, or it is open. Total the open cells in hours, not visits, because agencies book by the block and the count has to match that unit.

Sort the gaps by type

Recurring gaps repeat every week, such as a job that runs through the middle of the day. Scheduled gaps fall on known dates, such as a standing appointment for the helper. Unplanned gaps include a sick day for the helper or an urgent trip. Size the recurring gaps first and build the standing schedule from them. Keep unplanned gaps out of the standing schedule, and ask the agency separately how it handles same-day requests and whether it has open capacity at that hour.

Match each gap to a visit block

Every agency sets a shortest visit it will book. A gap shorter than that minimum cannot be filled by a standard booking, so ask for the minimum before you add up the grid. Ask also whether one block can be split between two caregivers and who makes that decision. Write down the answer, because the split changes who the family calls when a block goes wrong.

Check weekends and planned trips

Weekend staffing often differs from weekday staffing, so ask for weekend hours in writing rather than relying on the weekday schedule. For a planned trip of several days, ask how the agency records the absence, which blocks it holds, and whether the same blocks can restart on return. Those answers belong in the paperwork before the trip, not in a phone call from the road.

Questions to ask before you choose

  • What is the shortest visit you book, and what do you suggest for a gap shorter than that?
  • Can one block be split between two caregivers, and who decides?
  • If the family helper cancels a block on the same morning, what is the process, and how much notice do you need?
  • Who confirms weekend hours, and in what form will I receive them?
  • Which person in the office takes a same-day change, and when does that office close?

Check the local supply before you commit

In a county where few home care businesses serve the older population, open blocks can take longer to fill, and an agency may have capacity only at certain hours. Read Finding help where the supply is thinnest and How to read a caregiver-supply map for your county before you assume an agency can fill a late-evening or weekend gap.

Write the plan down

Keep one page with the grid, the gap list sorted by type, the agency's answers in writing, and a named backup for unplanned gaps. The backup is a second person the family can call, not a promise from an agency. The plan covers non-medical hours such as companionship, meal support, and household tasks. Health questions go to the family's doctor, and this page leaves those decisions with the family, the doctor, and the pharmacist.
