This question comes up in almost every intro call: "Did the tablet delay his speech?" My honest answer is this: the issue is often less about the screen itself and more about what the screen replaces. In this post I want to share both what the science says and concrete, doable suggestions for home — without manufacturing guilt, but without softening the truth either.

What grows language?

Language grows through reciprocal interaction. Call it the "serve and return" loop: the child makes a sound or looks at something, the adult responds meaningfully, the child responds again… What builds language is precisely this back-and-forth. A one-way screen can't form that loop; the child speaks, but the screen doesn't turn back and answer.

Here's the key idea: displacement. Every minute a child spends in front of a screen replaces the words they would otherwise hear and the live interaction they would otherwise have. The problem is often not that something "bad" is on the screen; it's that the conversation that should be happening isn't.

Is "educational content" enough?

Unfortunately not — at least not at a very young age. Research shows that children under 2 struggle to transfer information from a screen to real life; the literature calls this the "video deficit." So even content marketed as "educational" does not, at this age, replace learning from a live human. For a young child, the best "app" is the adult in front of them.

Age-by-age recommendations

The frameworks of the World Health Organization and the American Academy of Pediatrics largely overlap:

  • Under 18 months: Avoid screens apart from video chat (for example, with a faraway grandparent).
  • 18–24 months: If you must, choose quality content and always be there alongside — watch together, talking about it.
  • 2–5 years: Limit to roughly 1 hour a day and watch together where possible.
  • At every age: Keep meals, the time before sleep, and playtime screen-free.

Do screens "delay speech"?

Saying flatly that "screens delay speech" is too blunt — the cause-and-effect isn't that simple. But there's a large body of research linking high screen time with weaker language skills, and the strongest explanation is, again, the same: lost interaction. So screens aren't the sole culprit; but "more screens" usually means "less back-and-forth talk," and that means "less language."

The richest "content" you can give a child is your voice and your face turned toward them.

Practical suggestions for home

  1. If you're watching, watch together and think out loud. "Look, the bear is looking for honey! Do you think he'll find it?" Turn one-way viewing into a conversation.
  2. Don't leave the TV on in the background. A background screen reduces adult–child talk even when no one is watching.
  3. Turn dead time into talking time. Mealtimes, bath time, car rides — conversation instead of a screen.
  4. Look at your own screen habit too. A child also models the time you spend on your phone.
  5. Choose the book, and the same book over and over. Repetition gives the child the courage to say the next word.

Do you have a concern?

You don't need to cut screens out of your life entirely; the goal is to set the balance in favour of interaction. But if you have a worry about your child's language development independent of all this — late talking, few words, being hard to understand — don't leave it in the shadow of the screen debate. Let's assess the situation together in an intro call; whether there's a genuine delay or whether it's a matter of giving it time, let's see it together. I cover the signs of late talking and when to seek support in detail in my post on late talking.
