Early Signs of Childhood Apraxia of Speech at 18–24 Months

At 18 to 24 months, almost every toddler talks at their own pace — so how do you spot a difference that's about the brain planning speech, not just "taking their time"?

In short

Childhood Apraxia of Speech (CAS) is a motor-planning difference: a toddler's brain has trouble coordinating the lips, tongue and jaw to make sounds on purpose, even though the muscles themselves are strong. At 18–24 months it is genuinely hard to confirm — but early signs to watch include very limited babble and few spoken words, vowels that sound "off", trouble copying simple sounds when you ask, and a child who clearly understands far more than they can say. These are gentle flags to observe and discuss with a speech-language pathologist — not a diagnosis you can make at home, and not something to panic about.

Early signs to watch at 18–24 months

With sounds and babble

• Limited or quiet babbling as a baby, with fewer varied consonant sounds (less "ba-da-ga-ma") than other toddlers
• A small set of sounds and words that doesn't grow much month to month
• Vowels that sound unclear or distorted, not just consonants

With trying to talk

• Visible effort, groping or "searching" mouth movements when attempting a word
• The same word said differently each time — "baba", then "bada", then "da" for the same thing
• Difficulty imitating sounds or words on request, even when keen to communicate

The telling gap

• Strong understanding — your toddler follows instructions, points, knows names — but speech lags well behind
• Leaning heavily on gestures, pointing or leading you by the hand because words won't come out

What sets CAS apart from an ordinary late-talker pattern is inconsistency (the word changes each attempt) and the comprehension–speech gap — they clearly know what they want to say, but the motor plan won't hold together.

When to seek a check

Many toddlers with few words at this age simply bloom a little later, so these signs are reasons to observe and ask, not to alarm. A true CAS picture usually becomes clearer once a child is attempting more words — often closer to 2.5–3 years — so early on, the right step is a speech-language assessment that tracks how speech is developing rather than a fixed label. Bring it forward sooner if babble has been very limited, if words aren't emerging at all by around 18–24 months, or if your instinct says something is harder than it should be.

The Pinnacle way

At Pinnacle Blooms Network, we start by celebrating how your child already communicates — sounds, gestures, intent — and build from there. Focused, playful speech therapy for suspected apraxia uses frequent, motor-based practice to help the brain plan and repeat sounds with growing confidence. A clinical AbilityScore® and any diagnosis are formed only at a Pinnacle Blooms Network centre under qualified clinician care; nothing here is a diagnosis. Across 70+ centres in 4 states, 700+ therapists and 4.95 lakh+ families served, our aim is steady, strengths-first progress.
