YOUR QUESTION. A CLEARER NEXT STEP.
When to be concerned about your child's communication
Mild differences in how quickly a child talks are common and often resolve on their own, but it's worth a developmental check if your child isn't babbling by 9–12 months, has no clear words by 16–18 months, isn't joining two words by age 2, loses skills, or doesn't seem to understand or respond as expected. Communication is more than speech — listening, gestures and shared attention matter too. AbilityScore® is part of Pinnacle’s developmental assessment. Diagnosis, where needed, requires an appropriately qualified healthcare professional.

Every child finds their own voice in their own time — but knowing the gentle signposts helps you act early, with confidence rather than worry.
In short
Mild differences in how quickly a child talks are common and often catch up on their own. It's worth a developmental check if your child isn't babbling by around 9–12 months, has no clear words by 16–18 months, isn't joining two words by age 2, or seems not to understand or respond to you as expected. Trusting your instinct early is never wasted — a check brings reassurance far more often than concern, and where support helps, starting sooner makes the biggest difference.
Gentle signposts by age
Communication is far more than speech — it includes how your child listens, understands, gestures, makes eye contact, takes turns and shares attention. A useful rule is to look at the whole picture, not a single milestone:
- By 9–12 months — babbling ("bababa", "dada"), responding to their name, looking where you point, and using gestures like reaching or waving.
- By 16–18 months — a handful of clear words, pointing to show you things, and following simple instructions like "give me the ball".
- By 2 years — joining two words ("more milk"), a growing vocabulary, and understanding much more than they can say.
- At any age — it's worth a check if your child loses words or skills they once had, rarely makes eye contact or shares attention, doesn't respond to sounds or voices, or if you simply feel something is different.
If your child understands you well and communicates through gestures and pointing, that is a reassuring sign even when spoken words are slower to arrive. A hearing check is also a sensible first step whenever speech is delayed.
Why early matters
The early years are when the brain is most adaptable, so well-timed support builds skills quickly and naturally through play. Seeking a check is not about labelling your child — it's about understanding how they communicate best and giving them every opportunity to be understood.
The Pinnacle way
AbilityScore® is part of Pinnacle’s developmental assessment. Diagnosis, where needed, requires an appropriately qualified healthcare professional — never from an app or checklist. Our clinicians map your child's listening, understanding and expression to build a plan that fits them, through warm, play-based speech and language therapy. You can learn how your child's profile is built with the clinician-administered AbilityScore®, and explore more on child development at every stage.

CONNECT THE ANSWER TO YOUR CHILD’S DAY
Something to notice. Something to discuss.
What to notice
Watch for no babbling by 9–12 months, no clear words by 16–18 months, no two-word phrases by age 2, loss of words or skills once gained, little eye contact or shared attention, and not responding to sounds or their name — a hearing check is a sensible first step.
In everyday life
Talk through your day in simple, repeated phrases and pause to give your child time to respond — even a gesture, sound or look back is communication, and naming what they show interest in builds their words naturally.
Bring your observations and questions to your child’s professional. Choose activities that suit your child’s comfort, abilities and agreed plan.
Bring your questions to a first visitQuestions families ask
Is it normal for my child to talk later than other children?
Yes — there's a wide normal range, and many late talkers catch up beautifully, especially if they understand well and communicate through gestures and pointing. A check is still worthwhile if words are slow to arrive, simply for reassurance and to rule out things like hearing difficulty.
My child understands me but doesn't speak much. Should I worry?
Strong understanding is a reassuring sign. Still, if spoken words are well behind the typical guides for their age, a developmental and hearing check helps you understand whether gentle support would help expression catch up to comprehension.
At what age can communication be properly assessed?
Communication can be observed meaningfully from infancy through babbling, responses and gestures, and a structured assessment becomes increasingly informative from around 18 months to 2 years. If you have concerns at any age, an early check is always appropriate.
