YOUR QUESTION. A CLEARER NEXT STEP.
Key communication milestones in early childhood
Early communication follows a clear sequence: cooing and smiling by 3 months, babbling and gestures by 9-12 months, first words around 12 months, two-word phrases by 24 months, and short sentences by 3 years. These are guides, not deadlines — steady progress matters most, and a gentle check helps if babble or gestures are absent by 12 months or words are lost.
In this answer 5 sections
Every coo, babble and first word is your child reaching out to the world — and there's a beautiful rhythm to how communication unfolds.
In short
Early communication grows in a predictable sequence: from coos and shared smiles in the first months, to babbling and gestures by the end of year one, first words around 12 months, and short phrases by age two. These are guides, not deadlines — children vary, and steady forward movement matters more than hitting a date exactly.

When a gentle check helps
Milestones describe most children, not every child. It is worth a developmental check if there is no babble or gesture by 12 months, no single words by 16 months, no two-word phrases by 24 months — or any loss of words or skills your child once had, at any age. A hearing check is always a sensible first parallel step, since hearing and talking grow together.
The Pinnacle way
At Pinnacle Blooms Network, our therapists see communication as connection — not just speech. A clinical AbilityScore® and any diagnosis are formed only at a Pinnacle Blooms Network centre under qualified clinician care; it is a clinician-administered structured assessment, never an online quiz. If you have a question, our speech therapy team can guide you on what is age-appropriate and when to simply keep watching.

Act Early." milestones, the American Speech-Language-Hearing Association, and the American Academy of Pediatrics' HealthyChildren guidance — all paraphrased here for parents.

CONNECT THE ANSWER TO YOUR CHILD’S DAY
Something to notice. Something to discuss.
What to notice
Seek a developmental check if there is no babble or gesture by 12 months, no single words by 16 months, no two-word phrases by 24 months, or any loss of words or social engagement at any age. Pair it with a hearing check.
In everyday life
Narrate your day aloud — name what you see, pause, and wait for your child's reply, even if it's just a sound. This back-and-forth turn-taking is how communication grows.
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
At what age should my child say their first word?
Most children say one or two first words around 12 months, often "mama", "dada" or a favourite object. There's a wide normal range — what matters is that babble, gestures and understanding are also growing. A gentle check is sensible if there are no single words by 16 months.
My child understands me but doesn't talk much — is that a concern?
Understanding (receptive language) often runs ahead of speaking (expressive language), and that's common. Keep encouraging back-and-forth and gestures. If your child isn't joining two words by 24 months, a friendly developmental check can offer reassurance or early support.
Are gestures like pointing really important?
Yes — pointing, waving and showing are powerful early communication, often appearing before words around 9 to 12 months. They show your child wants to share and connect. Absent gestures by 12 months are worth a gentle check.
