Screen time for babies and toddlers, without the guilt

For babies under one, the advice is no screen time at all. For children aged 2 to 4, aim for no more than one hour a day, ideally watched with an adult. Video calls with family are different. Feeding with cartoons, background TV and long solo phone time are the habits most worth changing.

How much screen time is okay for a toddler?

The WHO says no sedentary screen time for 1-year-olds, and no more than 1 hour a day for 2 to 4 year olds, with less being better.¹

The Indian Academy of Pediatrics is a little stricter. It advises no screens of any type before 2 years, and at most one hour a day of supervised screen time from 2 to 5 years.²

"Screen time" here means sitting and watching TV, videos or games on a phone, tablet or television. Short video calls with grandparents are a different thing, explained below.

Is any screen time okay for a baby under one?

No. The WHO does not recommend screen time for babies under one year.¹

When a baby is sitting still, the WHO suggests reading and telling stories with a caregiver instead.¹ Babies also need tummy time and floor play through the day.¹

A cartoon that keeps a baby quiet while you bathe once in a while is not a disaster. Daily viewing is the habit to avoid.

Do video calls with grandparents count as screen time?

Dr Dutta treats them differently. A video call is two-way: grandmother talks, your child babbles, grandmother answers. Cartoons do not answer back.

That back-and-forth exchange is how young children learn language. Keep the calls short and sit with your child so you can join in. For families spread between Kolkata, Bengaluru and abroad, these calls keep children close to grandparents, and she would not cut them.

Why can't babies learn words from videos?

Babies learn language mainly from live people who respond to them. Recorded speech, even from the same person, seems to teach them very little at this age.

In a classic experiment, 9-month-old American babies heard Mandarin from real speakers over 12 short sessions, and they kept the ability to tell apart Mandarin speech sounds. Babies who heard the same speakers only on video or audio recordings showed no such learning.³

This is why "educational" baby videos are not a shortcut. Talking, singing and reading with your baby is.

Does screen time cause speech delay in toddlers?

More screen time is linked with weaker language skills in young children. The evidence fits with screens playing a part, though it cannot prove cause in every child.

A review of 42 studies found that more hours of screen use and more background TV went with lower language skills. Educational programmes, watching together with an adult, and a later start were linked with better language.⁴

An Indian study from Tamil Nadu looked at 718 children under five. Children watched about 2.4 hours a day on average, and about 73 percent were above the recommended limit.⁵ More screen time went with developmental delay, especially in language and communication.⁵

Is screen time the cause, or do slow talkers just get more screens?

Probably both. Some children who are already struggling may be given more screens, but one large study that followed children over time suggests screen time can come first.

A Canadian study followed about 2,400 children. Higher screen time at 2 and 3 years predicted lower scores on a developmental screening test a year or two later.⁶ The effect was small, and one study cannot prove cause, but it is a reason not to wait and see.

For a parent, the practical message is simple. Cutting screens is low cost and safe, so it is worth doing while any other assessment goes on.

Can too much screen time cause autism?

There is no good evidence that screens cause autism. Autism is generally understood as a difference in early brain development.

A review of 16 studies found that autistic children tend to have more screen time and to start screens younger than other children. It also found that the long-term effects of screen use before age 3 have hardly been studied.⁷

You may see the term "virtual autism" on social media. It is not a medical diagnosis. Some toddlers with very heavy screen use have few words and poor eye contact, and improve once screens go and play comes back. Please do not assume it is "just screens" and wait. Get your child assessed, and reduce screens at the same time.

Is background TV harmful if my child is not watching it?

Yes. A TV playing in the room means adults talk less to the child, even if no one is really watching.

In a lab study, parents and toddlers played for an hour. When an adult programme played in the background, both the amount and the quality of parent and child interaction dropped.⁸

Another study recorded the sounds around young children at home. Each hour of audible TV went with fewer adult words heard by the child, fewer sounds made by the child, and fewer back-and-forth turns.⁹

If the news or a serial is on all day at home, try switching it off when your toddler is awake in the room.

Is it bad to feed my toddler while they watch cartoons?

Yes. Dr Dutta considers this the screen habit that does the most harm. Mealtime is a prime chance to talk, and a child eating in front of a screen does not learn to notice hunger and fullness.

Many children in Indian homes now eat only with a phone propped in front of them. Wean this step by step: smaller screen, then sound off, then screen across the room, then no screen. Eat together and talk about the food. There will be a few difficult meals, and then it gets easier.

Does screen time affect my toddler's sleep?

Yes. Screen use, especially in the evening, is linked with poorer sleep in babies, toddlers and preschool children.¹⁰

The research quality is low, but the advice to cut evening screens is safe and easy.¹⁰ Toddlers aged 1 to 2 need 11 to 14 hours of good sleep in 24 hours, including naps.¹

My rules: no screens in the hour before bed, no TV in the bedroom, and no phone to settle a child to sleep. Use a bath, a book and a song instead.

Are educational apps and rhyme videos good for toddlers?

Quality and company matter more than the label. Educational programmes and watching together are linked with better language, but they do not replace talking and play.⁴

The American Academy of Pediatrics also stresses that parents share media use with young children, and that screen time must leave room for other healthy activities.¹¹

If your child of 2 years or more watches something, pick slow programmes with clear speech, sit with them, and talk about what you see. Avoid autoplay and short-video apps. They are built to keep everyone watching, adults included.

Does my own phone use affect my child?

Yes. Children copy us, and a parent on a phone talks and responds less.

In the Tamil Nadu study, children's excess screen time was linked with their mothers' screen time and with screen use at bedtime.⁵ Dr Dutta finds this the hardest habit to change, including in her own home.

Try phone-free times for the whole family, such as meals, the first hour after coming home, and bedtime. Keep the phone in another room during play.

How do I cut down my toddler's screen time without tantrums?

Expect protest for a week or two, then much less. Make the change gradual and replace screens with something else, not with nothing.

• Start with the most important times: meals and bedtime.
• Agree the rules with everyone who cares for the child, including grandparents and the helper.
• Keep phones and tablets out of sight and out of reach.
• Give a warning before screen time ends, then switch off calmly.
• Keep a basket of simple toys and books ready for the moments you used to hand over the phone.

What can I do instead of screens to help my child learn?

Ordinary daily life with lots of talk is enough. Reading, storytelling, singing and puzzles with an adult are what the WHO recommends for quiet time.¹

• Talk through what you do: cooking, dressing, shopping at the bazaar.
• Read picture books in Bengali, Hindi, English or any family language.
• Sing rhymes and play clapping games.
• Give pots, spoons, boxes and blocks for free play.
• Go outside every day, even for a short walk downstairs.

Grandparents are often wonderful at stories and rhymes once they are asked to do this instead of handing over the phone.

When should I see a doctor about my child's screen use or speech?

See your paediatrician if any of these apply:

• Your child is not babbling, pointing or responding to their name by the first birthday.
• Your toddler has very few words, or is not putting words together, compared with other children their age.
• Your child has lost words or skills they used to have.
• Your child seems uninterested in people or makes little eye contact.
• Removing screens causes extreme distress that does not settle after a couple of weeks.
• You want help making a family plan to cut screen time.

Do not wait to "see if it improves" once screens are reduced. Get the assessment and cut screens at the same time.
