When a household includes young children, the help for an older adult has to fit around school runs, naps, and the adults' work hours. The hired hours are for the older adult. Planning starts by describing the house hour by hour, not by choosing a total first and hoping the calendar fits.

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.

Map the household day first

Draw one row for each weekday. Mark when children leave for school, when they come home, when the adults are out, and when the older adult's usual routine is busiest. Visits that land on the edges of these blocks need the most planning. The gap often sits at the school handoff, not in the morning.

Decide what is not the aide's job

Ask the agency in writing whether its caregivers provide any childcare. If childcare is not part of the agreement, the family keeps those hours and should not assume a visit covers them. Do not leave a caregiver in charge of a child unless the written agreement says so.

Set the house rules for the visit

Agree on which rooms children may enter during a visit, who answers the door when a child is home, and what a child should do when the caregiver is in the older adult's room. Put the rules on a shared sheet that every adult can read, not in one adult's memory. Ask how the agency handles a visit that runs into a school pickup, because that is where a schedule usually breaks.

Compare agencies on household fit

When you call agencies, bring the day map and ask which blocks they can staff, how wide the arrival window is, and what happens when a visit runs long. Our guide to How to read a caregiver-supply map for your county explains why availability differs from one county to the next, which can change how many agencies you can ask in the first place.
