Why the 8pm dose is the one that slips
Missed tasks are usually a memory problem, not a caring problem. There is a technique with real evidence behind it.

Almost nobody misses a dose because they decided not to give it. They miss it because 8pm arrived while they were doing something else, and by the time they remembered, the window had closed.
Researchers have studied this exact problem for decades. The technique that works best is called an implementation intention, which is a formal name for something very simple. Instead of holding an intention like "I will give Bella her tablet tonight", you decide in advance on the exact moment and place: "At 8pm, when I sit down in the kitchen, I give Bella her tablet."
Why it works
Holding a plan in your head costs attention all evening. Tying the action to something you are going to encounter anyway costs nothing, because the kitchen does the remembering for you. The trigger does the work instead of your willpower.
Across 94 studies covering everything from exercise to voting, people who made if-then plans reached their goals substantially more often than people who simply intended to. The effect was strongest for taking medication on time, which is the closest thing in the research to what a sitter does.
What this looks like on a sit
- Read the plan once when you arrive and pick a physical trigger for each timed task. The kettle, the back door, feeding your own pet.
- Say the plan out loud once, in the form "when X, then Y". Writing or saying it makes it stick better than reading it.
- Sign each task as you do it rather than at the end of the day. A late sign records the care but does not clear a miss, and the window is usually an hour.
- If a time genuinely will not work, message the owner and ask them to move it. A changed plan is not a miss.
The honest limit
Reminders and triggers are scaffolding, not a personality change. In one study people receiving prompts followed through 82% of the time against 49% for people who got none, but follow-through dropped sharply once the prompts stopped. Treat the plan as something you rebuild at the start of every sit rather than a habit you now have.
