Screen Time for Kids: How Much Is Too Much and How to Set Limits

It is 5 p.m., dinner isn’t ready and the tablet is the only thing standing between you and chaos. Or your teenager has been on their phone since breakfast, and you can’t tell whether that is normal or a problem. Either way, a quiet voice asks: Is this too much?

Screen time is one of the most common worries in modern parenting, and it is surrounded by conflicting advice, scary headlines and guilt. This guide explains what health guidelines recommend at different ages, what research does and doesn’t show, and ten practical ways to set limits that work for your family.

What do the guidelines say?

Guidelines vary, but the main health bodies broadly agree on a pattern.

Under 18 months

The American Academy of Pediatrics (AAP) advises avoiding screen use, other than video chatting with family, in this age group. The World Health Organization (WHO) recommends no screen time at all for children under one.

18 to 24 months

If you want to introduce media, choose high-quality programming and watch it together so you can help your child understand it. Avoid solo use.

Ages 2 to 5

The AAP suggests limiting non-educational screen use to about one hour a day of high-quality programming, with parents co-viewing when possible. The WHO says no more than one hour a day for children aged 2 to 4, and that less is better.

Ages 6 and older

There is no single “magic number.” The AAP encourages parents to set consistent limits, make sure screens don’t replace sleep, physical activity or other healthy behaviours, and to keep some times and places media-free. It recommends creating a family media plan tailored to your household.

These are guidance, not laws. The point is to protect the things children need most: sleep, movement, play, conversation and time with people.

What does the research show?

The picture is mixed, and it is worth being honest about uncertainty.

• Early childhood. In a large study of young children, more screen time at ages 2 and 3 was associated with poorer performance on developmental screening tests at ages 3 and 5. The study shows an association, not proof that screens caused the difference, but it fits a wider concern that screens can crowd out interaction and play.
• Sleep. Screens close to bedtime, especially stimulating content and devices in bedrooms, are linked with later bedtimes and less sleep, which affects mood, behaviour and learning.
• Mood and mental health. Some studies link heavy use, particularly of social media, with anxiety, low mood and poorer wellbeing, especially in adolescents. Effects tend to be small on average, vary a lot between children and are hard to separate from other factors.
• Content and context matter. Educational, age-appropriate content watched with a caring adult is very different from passive, fast-paced or violent content consumed alone.
• What it displaces. Many concerns come from what screens replace: physical activity, sleep, outdoor play, reading and face-to-face contact.

The upshot: it isn’t only about minutes. The quality of content, the time of day, whether an adult is involved and what else is happening in the child’s life all count.

Signs screen use may be a problem

Consider stepping back if your child:

• has trouble sleeping, or is tired and irritable
• resists stopping and has intense meltdowns when devices are removed
• is losing interest in friends, hobbies, or activities they used to enjoy
• is falling behind at school or avoiding homework
• seems anxious, low or withdrawn, especially after using social media
• is hiding use or lying about it
• has physical symptoms such as headaches or eye strain
• is exposed to content that frightens or upsets them, or to contact from strangers

These are signals to pay attention and adjust, not to panic.

10 ways to set healthy screen time limits

1. Make a family media plan

Sit down together and agree on the basics. Include:

• When screens are allowed (after homework, weekends)
• Where they can be used (not in bedrooms, not at the table)
• How long, at a level that leaves room for sleep, play and activity
• What content is okay
• What happens when rules are broken

Involving older children in creating the plan makes them more likely to stick to it. Write it down and put it on the fridge.

2. Protect sleep

Sleep matters more than almost anything for children’s mood and learning. Try:

• No screens for at least an hour before bed
• Charge devices outside bedrooms overnight
• A wind-down routine: bath, story, quiet talk

This is one of the most worthwhile rules to enforce. If your teen is struggling with racing thoughts at night, our guide to how to fall asleep when your mind is racing may help.

3. Create screen-free times and places

Some anchors help the whole family:

• Meals: no phones or TV at the table
• Bedrooms: no devices overnight
• Car journeys: conversation or music, sometimes
• Family time: a regular game, walk or activity
• The first hour after school or waking up

Predictable “no screen” zones reduce arguments because they aren’t decided in the moment.

4. Choose quality and watch together

Not all screen time is equal. Prioritise content that is:

• Age-appropriate, with a slow pace for young children
• Educational, creative or interactive
• Free from ads and violent content
• Something you can discuss together

With younger children, co-viewing and talking about what you see turns passive time into shared learning. With older children, show interest in what they play and watch.

5. Balance with other activities

Make sure the rest of the day is full. Children need:

• Active play and physical movement every day
• Outdoor time
• Unstructured play and boredom (it fuels creativity)
• Reading and hobbies
• Face-to-face time with family and friends

When there are good alternatives, screens are less likely to fill the gaps.

6. Model the behaviour you want

Children watch us. If parents are constantly on phones, rules for kids feel hypocritical. Try to:

• Put your own phone away at meals and during conversations
• Avoid scrolling in front of children
• Talk about how you manage your own screen use

If you struggle yourself, how to stop doomscrolling offers practical steps for adults too.

7. Give warnings and use transitions

Stopping mid-game or mid-episode is hard. Make it easier:

• Give a five-minute warning: “Five more minutes, then we turn it off.”
• Use a visual timer
• End at a natural stopping point, such as the end of an episode or level
• Offer a next activity to move to: “After this, let’s make snacks.”

Big reactions at switch-off are normal for young children; see how to handle toddler tantrums.

8. Stay calm and consistent about limits

Rules work when they are predictable and calmly enforced. Avoid:

• Using screens as the only reward or punishment, which makes them more valuable
• Changing the rules according to your energy levels
• Shouting matches. See how to stop yelling at your kids.

Acknowledge feelings while holding the line: “I know it’s hard to stop. The rule is that we switch off at 6.”

9. Use tools wisely

Parental controls and settings can help, particularly for younger children: content filters, time limits, app approvals, and safe search. But they don’t replace conversation. For older children and teens:

• Talk openly about online risks such as bullying, strangers, sharing images and scams
• Agree on what to do if something upsetting happens: “You can always tell me, and you won’t be in trouble for telling.”
• Respect their growing need for privacy, with safety in mind

10. Keep the conversation going with older kids

Teens need autonomy, and rigid control tends to backfire. Ask about their online lives with curiosity, not suspicion: What do you enjoy? What is stressing you? Who do you talk to? Work out limits together, especially around sleep, homework and social media. See how to talk to your teenager.

Screen time by age: a quick guide

Age	Suggested approach
Under 18 months	Avoid, except video calls with family
18–24 months	If any, high-quality and watched together
2–5 years	About an hour or less a day, high-quality and shared; less is better
6–12 years	Consistent limits; protect sleep, activity, homework and family time; family media plan
Teens	Agree rules together; focus on sleep, mental health, safety, balance

Are all screens the same?

• Passive vs interactive: scrolling short videos differs from video-calling a grandparent, making a digital story, or learning a skill.
• Social media: for teens, the concern is often social comparison, sleep disruption and online bullying. See how to stop comparing yourself to others.
• Games: many are social and creative, but some are designed to keep players engaged. Look at how the game is monetised.
• Homework and learning: screen time for school isn’t the same as leisure time, though breaks matter.

Common mistakes

• All-or-nothing bans, which tend to increase fascination and secrecy
• Using screens to manage every difficult moment, so children don’t learn to handle boredom or big feelings
• Guilt spirals. You are allowed to use screens sometimes to cook dinner or rest
• Focusing only on minutes and ignoring content, sleep and mood
• Inconsistency, which invites negotiation

When to seek help

Consider speaking to your paediatrician, school counsellor or a mental health professional if:

• your child’s screen use is causing serious conflict, distress or significant changes in mood, sleep or school,
• they seem unable to stop despite negative consequences,
• they are being bullied, exploited or exposed to harmful content,
• they seem persistently anxious, low or withdrawn,
• they talk about self-harm or hopelessness.

If a child is in danger, contact your local emergency number. In the United States, you can call or text 988 for a crisis line. See our disclaimer for more.

Frequently asked questions

How much screen time is too much for a child?

There’s no single figure. Guidelines suggest none or minimal for under-twos, about an hour or less of quality content for preschoolers, and consistent limits for older children that protect sleep, movement and relationships.

Is screen time bad for toddlers?

Heavy screen use in very young children is associated with poorer developmental outcomes and displaces interaction. Limiting it and co-viewing high-quality content is advised.

Is educational screen time okay?

Quality matters. Age-appropriate, interactive content watched together is better than passive or fast-paced viewing, but it still shouldn’t replace play, sleep or conversation.

How do I get my child to stop playing games?

Use warnings, visual timers, natural stopping points and a next activity. Stay calm and consistent, and acknowledge feelings.

Should I ban screens completely?

For most families, total bans are impractical and can backfire. Clear, consistent limits and healthy alternatives work better.

At what age should a child have a phone?

There’s no fixed age. Consider your child’s maturity, your family’s values, their need for contact, and start with clear rules and supervision.

The bottom line

Screens are a part of modern childhood, not a villain to defeat. What counts is that they don’t crowd out sleep, movement, play and people. Agree a family plan, protect bedtime, set screen-free zones, model the habits you want and stay curious about your children’s online lives. Start with one change this week, such as phones out of bedrooms overnight, and build from there.
