Most families do not decide they have a problem. They find out they have been running one for months, because the favor kept working. You drove over on a Tuesday to check the stove. You texted the reminder about the appointment, then the one about the ride. You stopped asking him to do the thing because doing it yourself was faster. Each favor was small, and that is exactly why it hides the problem.

This guide is for the adult son who wants to know whether what he is doing is help or a quiet takeover his father has never agreed to. Dad may be fine. He may be running his own life with a system you cannot see. The count below tells you which it is, and it does not require you to judge his competence before you have the numbers.
Start the count
For fourteen days, keep one running list on paper or in a notes app. Every time you do something for Dad that he used to do himself, or that he could do if he had to, write one line: what you did, how long it took, and how you got the word that it needed doing. Do not judge the entries yet. Four sorts cover most of what lands on the list.
Reminders: texts, calls, or notes that get him to act on something he already knows about.
Checks: a drive over, a phone call, or a look through the window to confirm the house, the mail, the stove, or the car is as he left it.
Errands: groceries, pharmacy pickups, bills he would normally handle, anything you took off his plate without a conversation.
Speaking for him: calls where you answered a question on his behalf, or where the other party came to you first.
Read the count, not the mood
At the end of fourteen days, look at three numbers. First, how many lines there are. Second, how many lines repeat the same sort on the same schedule. Third, how many would have failed if you had not been available that day. The third number matters most. A favor you can plan around is a routine. A favor that only happens because you happened to be near the phone is the sign that the arrangement depends on one person and one stroke of luck.
You have the problem being solved, and not just a busy son, when most of these are true. The count grew over the two weeks. The same check repeats on a fixed rhythm that you now schedule your life around. You cannot leave town for a night without a plan that someone else has to run. Or you have started answering for him to the doctor's office, the bank, or a neighbor, and he has not heard about it from you.
What Dad sees from his side
From his chair, the favors look like nothing is happening. The stove is still off, the bill still got paid, the ride still showed up. That is the trap for both of you. He does not have to notice that he stopped doing things, and you do not have to say it out loud. Name it without a verdict: the list shows the work has moved to you, and you want to look at which parts should move on purpose instead of by accident. Bring the list, not a conclusion.
Do not present the list as proof that he cannot manage. Present it as a map of what your household currently carries. That keeps the conversation about the load rather than his judgment, which is where he is most likely to actually listen.
Sort each line before the next favor
Go down the list with a pen and mark each line one of three ways. Keep it with you if it is a one-time favor that does not need a standing answer. Hand it to a named person if a family member or a neighbor can take it on a fixed schedule, with a written note of what to do. Move it to an outside service only after you have read what that service actually does and what it will not do, in the written terms, before you sign anything.
The lines you mark for handing off are the ones to take to the next step, and that step is a short conversation with a plan for who covers which sort. Start with the checks, because they are the ones that fail silently.
Next move
Tonight, write the four sort names at the top of a blank page and sort the last three days of your list under them. Then count the checks alone. Pick the one check that would hurt most if it were missed, and name a backup for it this week. If you want help finding that backup in the St. Louis area, start with Local Help in St. Louis, and if you are still deciding how to open the conversation with Dad, read Start Here first.
