Worrying about Apraxia of Speech at 12–18 Months

If your little one is 12 to 18 months and the words just aren't coming the way you expected, it's natural to wonder about Childhood Apraxia of Speech — and the honest, reassuring answer is that this age is far too early to confirm it.

In short

At 12 to 18 months, Childhood Apraxia of Speech (ICD-11 6A01.0) cannot reliably be identified — and it is not the thing to worry about yet. CAS is a motor-planning speech difficulty that needs a child to be attempting words and sounds before a clinician can see the tell-tale inconsistency in how those sounds come out. What matters at this stage is watching the broader building blocks of communication: babbling, gesture, understanding and the drive to connect. These are patterns to observe gently, never a diagnosis to make at home.

What is appropriate to watch at 12–18 months

Rather than looking for apraxia, look for the early communication foundations that any speech later stands on:

• Babbling with variety — strings of sounds like "bababa", "dada", "mama" with changing consonants
• Gestures — pointing, waving, reaching up to be picked up, showing you things
• Understanding — responding to their name, simple requests ("give me the ball"), familiar words
• Social connection — eye contact, sharing smiles, turn-taking in little back-and-forth games
• First words emerging — often a handful by 18 months, though range is wide

A quiet or limited spoken vocabulary at this age is common and frequently catches up. The signs that genuinely deserve attention now are different: very little or no babbling, no gestures by around 12 months, not responding to their name, or losing skills they once had — these warrant a general developmental check, not a CAS label.

When CAS becomes meaningful to assess

A reliable look for apraxia usually becomes possible from around age 2 to 3 and beyond, once your child is attempting more words and a speech therapist can observe whether sounds are produced inconsistently and with effort. Until then, the kind and useful step is to monitor the foundations above and, if anything feels off, have an unhurried developmental conversation.

The Pinnacle way

A clinical AbilityScore® — a structured, clinician-administered assessment — and any diagnosis are formed only at a Pinnacle Blooms Network centre, under qualified clinician care, never from an online form or a home checklist. Drawing on 2.5 billion+ data points and 25 million+ therapy sessions across 70+ centres, our therapists look at the whole picture of how your child communicates and connects, then guide the right next step. If words are slow to come, gentle, play-based speech therapy supports the foundations long before any label is ever needed.
