Screen Time for Babies and Toddlers: What the Research Says

Evidence-based guidance on screen time for children under 3 — what the AAP recommends, why it matters, and how to use screens wisely if you choose to.

By uWish Baby Editorial

Screens are everywhere. From video calls with grandparents to educational apps to TV in the background, digital media has become woven into daily life. For parents of babies and toddlers, the question isn’t whether screens exist — it’s how to navigate them in ways that support healthy development.

The research is clear on some points and evolving on others. Here’s what we know about screen time in the early years.

What the research shows

Language development

Multiple studies have found associations between early screen exposure and delayed language development. A 2017 study in JAMA Pediatrics found that children aged 6 months to 2 years who spent more time with handheld screens had delayed expressive language skills.

Why? Language learning happens through back-and-forth interaction — what researchers call “serve and return” communication. Screens don’t adapt to a baby’s responses. Even “educational” videos don’t provide the responsive, contingent interaction that builds language.

However, video chat is different. Research shows that babies can learn from video calls because the person on the other end responds to them in real time. The AAP makes an exception for video chatting.

Attention and self-regulation

Fast-paced media with quick cuts and constant stimulation may affect developing attention systems. Some research suggests that early exposure to rapid scene changes is associated with shorter attention spans later in childhood.

Background TV is particularly problematic. Studies show that even when children aren’t directly watching, background television disrupts play quality, reduces parent-child interaction, and is associated with attention difficulties.

Sleep

Screen use before bed affects sleep in multiple ways:

  • Blue light suppresses melatonin production
  • Content can be emotionally stimulating
  • The “just one more” effect delays bedtime

A 2015 meta-analysis found that screen time is consistently associated with shorter sleep duration and delayed sleep onset in children.

Physical health

Screen time is sedentary time. While this matters less for infants who aren’t mobile anyway, it becomes increasingly relevant as toddlers develop. Screen time displaces active play, which is crucial for motor development and establishing healthy activity patterns.

AAP recommendations by age

The American Academy of Pediatrics provides specific guidelines:

Under 18 months:

  • Avoid screens other than video chatting
  • No evidence that educational programming benefits babies
  • Background TV should be avoided

18–24 months:

  • If introducing digital media, choose high-quality programming
  • Co-view and co-engage — watch together and talk about what you see
  • Avoid solo viewing
  • Limit to occasional use, not daily routine

2–5 years:

  • Limit to 1 hour per day of high-quality programming
  • Co-view when possible
  • Avoid screens during meals and for 1 hour before bedtime

Why babies don’t learn from screens

Babies learn through interaction, repetition, and real-world experiences. Here’s why screens don’t provide what they need:

The video deficit: Research consistently shows that babies learn less from video than from live interaction. A 2003 study found that 12-month-olds learned sign language from live instruction but not from video instruction.

Symbolic understanding: Babies under 18 months don’t understand that images on a screen represent real objects. They can’t transfer learning from 2D to 3D.

Passive vs. active learning: Screens provide information; interaction builds understanding. A baby learns “ball” by holding a ball, feeling its texture, throwing it, and hearing you name it in context — not by seeing a picture of a ball.

Attention requirements: Educational content often requires understanding that exceeds a baby’s cognitive abilities. What’s labeled “educational” for babies rarely is.

The reality of modern parenting

The AAP guidelines are based on optimal child development — but parenting happens in the real world. Sometimes you need 15 minutes to shower, cook dinner, or preserve your sanity. The goal isn’t perfection; it’s intentionality.

If you use screens occasionally:

  • Don’t feel guilty — occasional use won’t harm your child
  • Choose calm, slow-paced content over fast stimulation
  • Stay nearby and check in
  • Prioritize high-quality interaction the rest of the day

If you’re a working parent relying on screens:

  • Focus on quality over quantity during the hours you’re together
  • Enlist caregivers to prioritize non-screen activities
  • Use weekends for device-free family time

Making video calls work

Video chatting is the one screen activity the AAP encourages for babies. It supports social connection and language development. Tips for successful video calls:

Set up the environment:

  • Prop the device so your baby can see the screen hands-free
  • Ensure good lighting on your baby’s face
  • Minimize background noise

Facilitate interaction:

  • Sit with your baby and help them engage
  • Encourage the person on the other end to be animated and responsive
  • Use props — books, toys, songs
  • Keep calls relatively short (5–10 minutes for babies)

Be patient: Babies may not look at the screen, may get distracted, or may lose interest quickly. This is normal.

If you choose to introduce screens after 18 months

Select content carefully:

  • Slow pacing with clear cause-and-effect
  • Real objects and people rather than abstract animation
  • Interactive elements (asking questions, waiting for responses)
  • No commercials or fast cuts

Examples that meet these criteria: Sesame Street (older episodes), Mister Rogers’ Neighborhood, simple nature documentaries with calm narration.

Co-view and engage:

  • Watch together rather than using screens as a babysitter
  • Talk about what you see: “Look, the bird is flying. Where is the bird going?”
  • Connect screen content to real life: “We saw a dog on the show. Where is our dog?”

Set boundaries:

  • Use screens at predictable times, not as constant background
  • Turn screens off when not actively watching
  • Keep screens out of bedrooms

Reducing screen time: practical strategies

For babies under 18 months:

  • Put your phone in another room during playtime
  • Use audio (music, podcasts, audiobooks) instead of video for background stimulation
  • Keep the TV off unless you’re actively watching something
  • Make one room in your home screen-free

For toddlers:

  • Rotate toys to maintain interest
  • Get outside daily
  • Involve your child in household tasks (they’re more interesting than you think)
  • Keep books accessible and read frequently
  • Use timers to make screen limits concrete

FAQ

My baby loves watching TV. Is that bad?

Babies are attracted to screens because they’re designed to capture attention — bright colors, movement, and sound. This attraction doesn’t mean screens are good for them. Babies also love sugar, but we don’t feed it to them because of their preferences. Your job is to provide what’s developmentally appropriate, not what they enjoy most in the moment.

What about “educational” apps and videos for babies?

Research doesn’t support educational claims for baby media. The “educational” label is largely unregulated marketing. A 2014 study found that 90% of educational apps for young children had no research basis for their claims. Real learning happens through interaction, exploration, and play — not screens.

I need to work from home. How do I manage without screens?

This is genuinely hard. Strategies:

  • Work during naps
  • Tag-team with a partner when possible
  • Use safe independent play (play yards, activity centers) for short periods
  • Accept that some screen use may be necessary — minimize it and don’t guilt yourself
  • Consider childcare if work demands are high

Does background TV really matter if my baby isn’t watching?

Yes. Background TV has been shown to:

  • Reduce the quantity and quality of parent-child interaction
  • Disrupt focused play
  • Be associated with attention problems later
  • Expose children to age-inappropriate content

Turn the TV off when no one is watching.

Will occasional screen time ruin my child?

No. The research shows associations with problems at high levels of use or when screens replace interaction. Occasional, mindful use — especially if you’re engaging alongside your child — is unlikely to cause harm. The goal is balance, not elimination (which is impossible in modern life).
