Ideally, no screen should be the last thing before sleep. The American Academy of Pediatrics recommends no screens in the hour before bedtime, and the NHS says 30 to 60 minutes. Young children are especially sensitive to light in the evening, and dark mode or Night Shift hasn't been shown to fix it. If you like a story app, use it earlier in the routine, print the story, or keep the screen short, dim and shared, then finish with lights out.
Disclosure: we make Storynite, which shows stories on an iPhone or iPad. We think you should know what the guidance says anyway.
What the guidance says
- American Academy of Pediatrics: children and teens should avoid screens for 1 hour before bedtime (2016 media policy).
- NHS: don't let children look at laptops, tablets or phones in the 30 to 60 minutes before bed.
- Sleep Foundation: a bedtime routine of around half an hour, with activities like reading a book and talking about the day.
What the research shows
- Preschoolers are very sensitive to evening light. In a 2022 University of Colorado study of 36 children aged 3 to 4, even dim light (5 to 40 lux) suppressed melatonin by 70 to 99%, and in more than half of the children it hadn't recovered 50 minutes after the light went off (Hartstein et al.).
- E-readers delayed sleep in adults. In a 2015 Harvard study, adults who read on an iPad before bed took longer to fall asleep, had less melatonin and were less alert the next morning than when they read a printed book (Chang et al., PNAS).
- Night Shift didn't help. A 2021 Brigham Young University study of 167 young adults found iPhone Night Shift did not improve sleep compared with using the phone without it (summary).
We found no study showing that dark mode, warm colors or a dimmed screen make bedtime screen use safe for children. Treat them as comfort settings, not sleep protection.
Five ways to use a story app without hurting sleep
- Make the story earlier. Create it after dinner or during bath time, so the screen part is done well before lights out.
- Print it. Export the story as a PDF and print it, and bedtime is paper again. Storynite has PDF and ePub export for this.
- Read it yourself, aloud. Hold the device yourself, angled toward you, and let your child listen and look at the pictures. Keep the brightness low.
- Keep it to one story. One short story, then the screen goes away and the routine carries on: a song, a cuddle, lights out.
- End with talking, not the screen. The last few minutes can be you asking about the best part of the story, or the best part of their day.
Why we still think a story app can earn its place
The point of a bedtime story is the time together: a parent's voice, a predictable routine, and words. Reading aloud from birth is one of the American Academy of Pediatrics' core recommendations (2024 policy), and a 2019 Ohio State study estimated children read five books a day hear about 1.4 million more words by kindergarten than children who aren't read to (Logan et al.). An app that gets a tired parent reading a story about their child's own day, instead of skipping the story, can be worth a few minutes of screen, especially if you follow the steps above.
FAQ
Does dark mode help kids sleep?
There's no good evidence that it does. It makes a screen more comfortable in a dark room, but research on Night Shift found no sleep benefit. Keep screens out of the last 30 to 60 minutes before sleep where you can.
Are audio stories better than screens?
For the light problem, yes: an audio story with the screen off avoids it. Children still benefit from a parent reading to them and talking about the story.
Is an iPad better than a phone?
A bigger screen makes it easier to read together, but it's still a light source. The same advice applies: dim, short, shared and earlier.
