The Afternoon Nap Grows Long: How to Catch the Day-Night Flip Before It Sets In

A day and night that run in the wrong order rarely flip all at once. It starts with a nap that runs a little later each afternoon, until it reaches dinner and carries into the evening. Then the waking hours move into the dark, and the night becomes the time of the most activity. The shift is easier to slow down early, so it helps to know what it looks like at the start.

What the first signs look like

Watch for a nap that begins after lunch and runs past the time dinner used to happen. Watch for meals that move later, a restless hour before bed, and waking when the house is quiet. Watch for a person who seems fully awake at night but tired and slow in the morning. None of these alone says much. Together they say the rhythm is moving.

Keep a log for a week

Write down the time she wakes, the time she naps and how long the nap lasts, the time she eats, and the time she is up at night. Add one line for anything that changed around the same time, such as a new visitor, a shift in the schedule, or a new medicine that her doctor started. After a week, compare the lines. The log shows the drift more clearly than memory does, and it gives her doctor something specific to look at. Bring the log to the next visit and say when the change seems to have started.

Shape the afternoon, not only the night

Most of the work happens before dark. Keep the afternoon bright, with time outside or near a window if it is safe to do so. Keep any nap short and early in the day, and move the bigger activities into late morning and early afternoon, while energy is still high. Keep the evening quiet and the bedroom dark. If the flip has already started, the household may need an extra person for a few nights, so the one who sleeps nearby is not carrying every hour alone. Watch how the nights go before you decide what to add.
