Screens Before Bed and Toddler Sleep: What to Skip
The published advice is shorter than the shopping list built around it. The American Academy of Pediatrics says to turn off all screens at least 60 minutes before bedtime and to keep screens out of children’s bedrooms at night. The WHO says no screen time at all under age one, and no more than an hour a day from age two to four. That is essentially the whole evidence-backed intervention, and every part of it is free. The gadgets sold alongside it — toddler blue-light glasses in particular — are the part I would skip. Here is what I verified.
What the guidance actually says, by age Verified August 2026
Two bodies publish numbers, and they broadly agree. I pulled both on August 15, 2026.
The WHO’s guidance for under-fives is stated per age band:
| Age | Sedentary screen time | Sleep per 24 hours |
|---|---|---|
| Under 1 | ”Screen time is not recommended” | 14–17h (0–3 months) or 12–16h (4–11 months) |
| 1 year | ”Sedentary screen time … is not recommended” | 11–14h “including naps” |
| 2 years | ”No more than 1 hour; less is better” | 11–14h “including naps” |
| 3–4 years | ”No more than 1 hour; less is better” | 10–13h, “which may include a nap” |
The AAP’s page on screens for infants and toddlers puts the threshold at 18 months, because “it takes around 18 months for a baby’s brain to develop to the point where the symbols on a screen come to represent their equivalents in the real world.” Its limit after that: “Cap your child’s electronic entertainment time at 1 hour a day from age 18 months to age five.”
That cap is superseded, and the AAP has not updated its own parent page. In January 2026 the AAP published Digital Ecosystems, Children, and Adolescents (Pediatrics 157(2)), which drops the universal numeric limit in favour of content and context. The under-18-months caution stays. That is the AAP’s own site contradicting its own current policy.
Two lines on that page matter more for bedtime than the retired number. Screen viewing before 18 months “contributes to problems with sleep and attention.” And background TV counts: “just having the TV on in the background, even if ‘no one is watching it,’ is enough to delay language development.” If your evening has a TV murmuring in the corner while the toddler plays, that is inside the guidance, not outside it.
The 60-minute rule — and where two expert bodies disagree
This is the part worth knowing, because you will see both numbers quoted as gospel and nobody ever mentions that they are different.
The AAP’s healthy sleep habits page says: “To prevent sleep disruption, turn off all screens at least 60 minutes/1 hour before bedtime.” It also recommends “keeping all screens—TVs, computers, laptops, tablets and phones out of children’s bedrooms, especially at night.”
The American Academy of Ophthalmology, on its blue light page, recommends limiting screen time “in the two to three hours before you go to bed.”
So: sixty minutes from the pediatricians, two to three hours from the eye doctors. I am not going to average them into a fake number. Read sixty minutes as the floor, not the target — if bedtime is a fight at an hour, the next lever is a longer gap, not a purchase.
The clearest “don’t buy” on this whole topic Verified August 2026
Blue-light-blocking glasses for kids are marketed straight at this problem. The AAO’s own position, quoted from the page above:
“There is no scientific evidence that blue light from digital devices causes damage to your eye.”
And, on the product itself: “Skip the glasses that claim to protect your eyes against blue light, because of a lack of evidence that they are effective.” The Academy states it “does not recommend any special blue light-blocking eyewear for computer use.”
That is the eye specialists’ own body telling you not to buy the eye product — about as close to settled as this site gets.
What the AAO suggests instead costs nothing: “nighttime settings on your devices to minimize blue light exposure in the evenings.” Every phone and tablet has shipped with that toggle for years.
Free things that do the actual work
Ranked by how little they cost.
- The device’s own night mode. Named by the AAO, built into the hardware, zero dollars.
- Screens out of the bedroom. The AAP’s wording is a location rule, not a product. Moving a tablet to a kitchen drawer is the intervention.
- A fixed routine. The AAP’s shorthand for young children is “brush, book, bed,” alongside keeping “the same waking time (both on weekdays and weekends), mealtimes, nap time and play times.”
- A written family plan. The AAP’s Family Media Plan tool lets families set “screen-free zones (such as the dinner table, during homework and before bed).” Caveat: no page I could read states a price, so I will say it sits on AAP’s public parent site rather than call it free.
- Books instead of the tablet. Your library card covers the replacement activity, plus story times and often museum passes — the full list.
- Something to do in that last hour. Betteroo keeps a stack of screen-free things to do with a toddler, which is the practical gap the guidance leaves open — “no screens” is easy to say at 6pm and hard to fill.
Where money is genuinely worth spending: light, not lenses
The honest exception to the skip-the-gadget line is about the room, not the screen. In August, bedtime happens while it is still bright out — a toddler who was fine in January may have a west-facing window rather than a screen problem. Darkening the room is the one purchase I would make here, and it is cheap: grommet panels like the NICETOWN thermal insulated blackout curtains fit a standard rod with no rail install, which matters in a rental.
Whether to buy them at all, and what to get secondhand instead, is worked through in a sleep-friendly nursery on a freebies budget. The related question of what is safe to actually put in the cot at this age is covered in when a blanket is finally safe.
When the screen is not the problem
Worth saying, because this site exists to stop people spending money on the wrong diagnosis: cutting the evening screen only helps if the evening screen was the cause. A two-year-old whose total sleep is short across the whole 24 hours, or who is capping naps at the wrong point, will fight bedtime with or without a tablet.
If you are not sure which one you have, start with the total rather than the tablet — Betteroo’s breakdown of how much sleep a two-year-old actually needs is a reasonable place to check your numbers against the AAP and WHO ranges in the table above.
The wider point about which “free” sleep resources are actually free and which are lead magnets with a price at the end is the whole subject of our guide to free baby sleep help.
FAQ
How long before bed should screens go off for a toddler? The AAP says at least 60 minutes. The AAO suggests two to three hours. Treat 60 minutes as the minimum and extend it if bedtime is still a struggle — that costs nothing to test.
Are blue-light glasses worth buying for a child? The American Academy of Ophthalmology says to skip them, citing a lack of evidence that they are effective, and states there is no scientific evidence that blue light from digital devices damages your eye. That is the eye specialists’ own guidance.
Is background TV a problem if my toddler is not watching it? The AAP says yes — having the TV on in the background, even when no one is watching, is enough to delay language development. It counts toward the evening wind-down whether or not anyone is facing it.
What about a tablet with a kids’ bedtime mode? No published guidance from either body recommends a device as a bedtime aid. The rules both organisations actually publish are about time and location: turn it off an hour before, keep it out of the bedroom.
Does any of this apply to a baby under one? The WHO’s line for under-ones is that screen time is not recommended at all, so there is no evening allowance to manage. At that age the questions are about feeds, wake windows and the room.
