Do screens before bed affect my toddler’s sleep?
They can. The AAP advises turning screens off at least an hour before bedtime and keeping phones, tablets and TVs out of your child’s bedroom at night. The light from screens can disrupt melatonin, and exciting shows or games can leave a child more alert. Screens are often one part of a harder bedtime rather than the whole cause.
What the AAP recommends
The AAP’s guidance on screens and sleep has three parts:
- Stop screens at least an hour before bedtime.
- Keep phones and screens out of your child’s bedroom at night.
- Choose calm content. The AAP notes that an action-packed game or something intense can make children more alert and raise their heart rate, which makes falling asleep harder. It suggests relaxing or funny programs watched together instead.
The AAP also explains that the type of light given off by screens can disrupt the production of melatonin, the hormone that helps the body fall asleep.
Why young children are sensitive to evening light
A 2018 study exposed 10 healthy children aged about 3 to 5 to bright light for an hour before bed. Their melatonin fell by about 88% and stayed suppressed for at least 50 minutes after the light went off. A tablet held close to the face is not the same as a brightly lit room, but the study shows how responsive young children’s body clocks are to light at night.
Screens are often one piece of a harder bedtime. Actually Sleeping works with babies and toddlers from newborn on and fixes the whole evening, not just the last hour.
What it looks like at home
Parents often notice one of these patterns:
- Bedtime battles start the moment the show ends.
- Your toddler seems wired, not sleepy, at the time they should be winding down.
- Falling asleep takes longer on nights with a show than without.
- A show has become part of how your child falls asleep, and they ask for it again at night.
That last pattern is the one that matters most. When a screen becomes part of falling asleep, it works like any other sleep association: your child needs it to fall asleep, and asks for it, or for you, when they wake.
Why taking screens away often is not enough
Many families cut evening screens and find bedtime gets louder, not easier, for a while. The show was filling time, managing a tired toddler, and giving parents a break. Without something to replace it, and without a clear limit both parents hold, the protest moves to the routine. Babies are affected too: background TV in the room where a baby is falling asleep adds both light and noise.
Parents’ screens count as well, especially a phone lit up during night feeds or while sitting by the crib.

Mornings and daytime
The AAP’s sleep advice is about the evening. Daytime limits are a separate decision for your family and pediatrician. For sleep, the hour before bed and the bedroom matter most.

Frequently asked
How long before bed should screens go off for a toddler?
The AAP advises at least an hour before bedtime. It also recommends keeping phones, tablets and TVs out of your child’s bedroom at night, and choosing calm content when screens are used in the evening.
Does night mode or a blue-light filter make screens okay before bed?
The AAP’s advice is simply no screens in the hour before bed. Even with a filter, an engaging show or game can keep a toddler alert. A book or quiet play is the safer bet for sleep.
Is a calm show better than a game before bed?
The AAP suggests relaxing or funny programs watched together over action-packed games and movies, which can raise heart rate. Even so, aim to finish all screens at least an hour before bedtime.
