Early Signs of Childhood Apraxia of Speech at 12–18 Months

Every toddler babbles in their own time — so how do you tell a slow-and-steady talker from a little one whose mouth and words aren't yet clicking together?

In short

At 12–18 months, true Childhood Apraxia of Speech (CAS) cannot be diagnosed — it's a motor-planning difficulty that needs enough speech attempts to recognise, which usually means waiting until a child is trying words and short phrases. What you can watch for at this age are early warning signs: very little babbling or vowel-heavy sounds, a quiet repertoire of consonants, and difficulty imitating sounds. These are gentle flags to observe and discuss with a speech-language professional, not a diagnosis to make at home.

Early signs to watch at 12–18 months

CAS is about the brain planning and sequencing the movements of speech — so at this young age the clues are mostly about how few and how variable a child's sounds are, rather than a clear pattern.

Babbling and early sounds

• Limited or late babbling — fewer of those repetitive "bababa", "dada", "mama" strings than other children
• Sounds heavy on vowels ("ah", "oo") with very few consonants
• A small set of consonant sounds overall

Imitation and trying words

• Difficulty copying sounds or simple words when you model them
• Inconsistency — saying a sound or word one moment and not being able to repeat it
• Seeming to want to communicate (pointing, gesturing, leading you by the hand) but struggling to make the sounds follow

Feeding and mouth movements

• Some children have early feeding differences, though this alone is not a sign of CAS

What matters most here is the gap between a child's eagerness to communicate and the sounds they can actually produce — a child who understands well, points and gestures, but stays unusually quiet vocally is worth a friendly check.

When to seek a check

Many 12–18-month-olds simply talk later, and most catch up beautifully. Consider a developmental and speech check if your toddler is making very few sounds, isn't babbling with consonants, isn't trying to imitate you, or isn't using any words by around 15–18 months. Because true CAS needs more spoken attempts to identify, an early visit is usually about supporting communication now and watching closely — early support helps every late talker, whatever the eventual picture.
