Responsive Communication — Serve and Return Strategies for Toddlers

Language develops in the space between people. The quality of the exchanges your child has — particularly in the first three years — shapes how their language system develops. This page is about the responsiveness part: what happens when your child communicates, whether they use words or not.

Serve and return

Harvard’s Center on the Developing Child describes the key mechanism of early language and brain development as serve-and-return interaction: a child signals something (a look, a gesture, a sound, a word) — this is the “serve.” A caregiver notices and responds in a contingent, warm way — this is the “return.”

The return doesn’t have to be words. It can be:

• Making eye contact and smiling in response to a baby’s gaze
• Picking up what the child reached toward and naming it
• Imitating a sound your child made
• Saying “oh yeah!” and looking at what they’re pointing at
• Pausing to wait when they seem to be trying to communicate

What matters is that the response is contingent — connected to what the child just did — and warm — not perfunctory.

Respond to the intention, not just the form

One of the most important things a responsive communication approach asks of parents is to respond to what a child is trying to communicate — not just to what they produced.

• A child reaches toward the biscuit tin → respond to the request, name it (“biscuit? do you want a biscuit?”), and follow through
• A child says “bah” while pointing at a ball → respond as if it were “ball” — “Yes! Ball. Do you want the ball?”
• A child pulls your hand toward the door → respond to the intent (“you want to go outside?”) and give it language

Responding to communicative intent — even when the form is incomplete — tells the child that their communication works. That experience is a powerful motivator for more communication.

Narrate daily routines

The routines of an ordinary day — getting dressed, eating breakfast, having a bath, getting into the car — are rich language opportunities, precisely because they’re predictable. Predictable contexts help children learn vocabulary and sentence patterns.

You don’t need to keep up a constant running commentary — that can become background noise. A few sentences at key moments, connected to what’s happening, is enough.

• “Arms up! Now the shirt goes on. Pop — there’s your head.”
• “Splash, splash. Time to wash your hair.”
• “Let’s get your shoes. This one, then this one. There — done.”

Over time, these scripted phrases become the child’s own — they start to anticipate them, fill in the next word, or use them independently in similar situations.

Imitate your child

Imitating your child — repeating the sounds, words, or actions they produce — has two effects: it shows them that their output is interesting and worth responding to, and it creates a natural turn-taking exchange.

Try imitating a sound or word your child makes, then waiting. Many children will imitate back. This simple exchange is one of the foundations of conversational turn-taking.

This is particularly relevant for children using echolalia or scripts — a responsive approach meets them where they are rather than trying to replace their current communication system with a different one.

Reduce screen time during interaction

Screens are not the problem — passive parallel screen use during interaction is. When a screen is running in the background during meals or play, it reduces the number of contingent adult responses a child receives, because the adult’s attention is split.

This is not about eliminating screens — it’s about making sure that when you’re with your child, you’re available to notice and respond.

Talk about feelings and inner states

Children whose caregivers name emotions and inner states — “You’re frustrated. That’s tricky.” “You look excited!” “I think the dog is scared.” — tend to develop richer emotional language and better understanding of their own and others’ minds.

This kind of language also tends to be used in calmer, more connected moments — which makes it a natural part of a responsive communication approach.

When communication breaks down

Children who can’t communicate their needs effectively often express frustration through behaviour — tantrums, hitting, biting, or meltdowns. This is not a behaviour problem. It is a communication problem, and it is extremely common in children with speech or language delays.

A few strategies that help in the moment:

• Accept all forms of communication — pointing, pulling, vocalising, gesturing. Responding to these tells your child that their communication works, which motivates more attempts.
• Offer choices rather than open-ended requests. “Do you want the red cup or the blue cup?” is easier to respond to than “What do you want?”
• Give language to the situation — “You want the ball. It’s up high. Let’s get it together.” Naming what’s happening reduces the child’s need to express it through behaviour.
• Stay calm and close during a meltdown, without demanding speech. Expecting a child to use words when they are dysregulated is usually counterproductive.

As communication improves — whether through development, therapy, or AAC — frustration-driven behaviour typically decreases. The two are directly connected.
