What we treat / Childhood apraxia of speech
Childhood apraxia of speech (CAS)
Your child knows what they want to say; the message just gets scrambled between the brain and the mouth. CAS is a motor speech disorder: the brain has difficulty planning the precise, rapid movements that speech requires. The muscles aren't weak and the thinking is intact (ASHA). With the right therapy, often enough, children with CAS can make real progress.
Signs to watch
Clues that your child's speech difficulty may be motor-based
Features described by ASHA and Mayo Clinic. Only a motor-speech evaluation can tell CAS from its look-alikes.
Was a quiet baby, with little babbling between 7 and 12 months (Mayo Clinic).
First words came late and were missing sounds.
Says the same word differently every time. Today's “cookie” isn't yesterday's.
Short words come out clearer than long ones; new or long words collapse.
You can see the mouth searching: jaw, lips and tongue groping toward positions.
Stress lands oddly. The rhythm and melody of speech sound off.
Understands far, far more than they can say, and struggles to imitate even simple words on request.
Frustration is big, because the message is fully formed and the mouth won't cooperate.
How KidSLP helps
Different therapy, delivered more often, with honesty about what we know.
A careful motor-speech evaluation
We separate CAS from phonological disorders and dysarthria, and say “not sure yet” honestly when that's the truth. There is no single test; the diagnosis comes from skilled observation of how your child's speech behaves across tasks.
Motor-learning therapy, often
High repetitions of carefully chosen movement sequences, cued with touch, sight and sound, and zero non-speech “oral exercises,” because strengthening isn't the problem (ASHA). How often is planned with your family; online sessions can fill in between home visits.
Power words, AAC and a home team
A power-word list built with your family (names, needs, “I love you”) so early wins land where they matter. AAC as a bridge whenever helpful, so your child can communicate today (ASHA). Caregiver coaching for short daily practice bursts.

Everything else parents want to know
Open a section. Nothing here replaces an evaluation.
CAS looks different from other speech sound difficulties in a few telltale ways:
- Inconsistency: the same word comes out differently every time. “Mama” might be “mama,” “nana” and “baba” in one afternoon (ASHA).
- Trouble with transitions: difficulty moving smoothly from one sound or syllable to the next. Longer words fall apart while short ones survive (ASHA; Mayo Clinic).
- Prosody differences: stress lands on the wrong syllable or word, and speech can sound choppy or flat (ASHA).
- Groping: visible searching movements of the jaw, lips or tongue as the child works to find the right position (Mayo Clinic).
Looking back, many families remember early clues: a quiet baby who babbled less than expected between 7 and 12 months, and first words arriving late, often after 12–18 months, with sounds missing (Mayo Clinic).
CAS is not the same as a phonological disorder (patterned rule errors), a lisp (one stubborn sound), or dysarthria (true muscle weakness). Telling them apart is genuinely difficult, even for professionals, and the treatment for CAS is different. That's why an accurate diagnosis matters.
CAS is rare. Estimates suggest perhaps 1 in 1,000 children (Apraxia Kids), a fraction of the much larger group with other speech sound disorders. Because the signs overlap with more common conditions, CAS is both underdiagnosed and overdiagnosed: some children carry the label who shouldn't, and some who should, don't.
Most of the time, the cause of CAS is unknown (ASHA). When a cause is found, it's often genetic. Mayo Clinic notes genetic factors in roughly a third of cases, including FOXP2 gene changes. CAS can also be associated with conditions like galactosemia or chromosome differences, or with brain injury. For most families, though, there is no event to point to and nothing anyone did wrong.
CAS is diagnosed by a speech-language pathologist, ideally one experienced in motor speech disorders. There is no single test: the diagnosis comes from skilled observation of how your child's speech behaves across tasks. At KidSLP, that process is careful and unhurried, because getting this label right changes everything about treatment. It happens in your home or online, with you right there.
- A caregiver interview: babbling history, first words, what speech has done over time.
- A hearing test, always, plus medical referral when anything suggests an underlying condition (ASHA).
- An oral-motor exam: how the lips, jaw and tongue are built and how they move, including ruling out true muscle weakness (dysarthria).
- Speech tasks that reveal motor planning: repeating the same word several times (watching for inconsistency), building from short to longer words, imitating, and listening closely to prosody and transitions.
- An honest conclusion: CAS, a different speech sound disorder, or “not yet clear, here's the plan to find out.” Young children sometimes need therapy underway before the picture settles, and we say so plainly.
This is the heart of the CAS conversation: children with apraxia don't need more of the usual therapy. They need different therapy, delivered more often. Because CAS is a motor planning problem, treatment is built on motor learning: many, many repetitions of speech movement sequences, with multisensory cues (touch cues on the face, visual models, careful listening), and definitely not muscle-strengthening exercises, because the muscles were never weak (ASHA).
ASHA notes that therapy for CAS often starts at 3–5 times per week. How often is a decision we make with your family, and online sessions are a natural way to add practice between home visits. A coached practice partner at home multiplies every session.
The right approach helps children:
- Build reliable motor plans for the words that matter most: names, needs, “I love you”
- Climb from syllables to words to phrases with stable, practiced movement patterns
- Communicate now through AAC while speech is under construction; it supports the speech work, never replaces it (ASHA)
- Keep frustration from swallowing motivation, with small wins made visible every session
Tips for parents
What you can do at home, starting today
Practice small, practice daily
Five minutes of the power words, once or twice a day, beats an hour on Saturday. Motor plans are built by frequent reps.
Let them watch your mouth
Face-to-face, slightly slowed, so your child can see the movements they're trying to build.
Practice words, not exercises
Skip the straws-and-blowing routines; the muscles aren't weak (ASHA). Real words, real phrases, real reps.
Honor every attempt
Groping and misses ARE effort. Respond to the message (“You want the cookie? Cookie!”) and keep the trying safe.
Use the AAC everywhere
If your child has signs, boards or a talker, that's their voice today: meals, car, grandma's house. Speech practice continues alongside, never instead.
Build rhythm into practice
Songs, claps and sing-song repeats make movement sequences stickier, and a lot more fun.
Protect their spark
No “say it again” gauntlets in front of others, no comparing to siblings. Motivation is the fuel for ten thousand repetitions.
Keep a wins list
CAS progress comes in inches. Write down every new clear word. On hard days, that list is medicine for caregivers, too.
Through a child's eyes
Ava's story
Illustrative story. Ava is a fictional child, not a KidSLP client.
Meet Ava, three and a half, a dancer who never misses a beat, except when she talks. Ava was a quiet baby, late to her first words, and now the same word comes out three different ways in one snack time. She knows exactly what she wants to say. Her mouth keeps losing the map.
Morning: getting ready for the day
“Mama, buh… puh… muh—” Ava's jaw works, searching. Mom holds still and warm: no rushing, no guessing ahead. Then Ava taps the banana button on her talker, and breakfast is solved. “Banana! You told me perfectly.” Her talker isn't giving up on speech. It's making sure Ava never has to go without a voice while speech is under construction.
At preschool
At circle time, Ava's teacher gives her the song jobs: hand motions, drum beats, the big cymbal crash. Full participation, zero pressure to perform words on demand. When Ava says “bah!” for ball at the toy bin, her teacher answers the message, not the miss: “The ball! Rolling it to you!”
Afternoon: speech therapy with KidSLP
Ava's sessions are short, playful and packed, and there are more of them than most kids get: home visits plus online sessions in between, a rhythm her parents and her SLP worked out together, because motor learning runs on frequency. Today's target word is “mama,” practiced the CAS way: dozens of repetitions hidden inside games, gentle touch cues at Ava's lips for each “m,” a slow visual model to copy, and a sing-song beat, “MA-ma, MA-ma,” because rhythm is Ava's superpower. Every clean rep drops a pom-pom in the jar. The jar fills.
Evening: at home
After bath, the five-minute practice: this week's power words (mama, up, go, more, hi), five reps each, danced as much as spoken, then done. Dad logs the night's win in the notebook on the fridge: “UP — clear, twice!” The wins list is getting long enough to need a second page.
Over time
Progress comes in inches, then one day it comes in a phrase. Months of reps, cues and pom-pom jars, and one bedtime, unprompted, clear as a bell: “Wuv you, Mama.” Mom cries. Ava giggles and says it AGAIN, the same way twice, which, for apraxia, is its own kind of victory. The map is holding. There's a long road ahead, and Ava's family knows it. They also know the way.
At KidSLP, we help children like Ava find their voice — because every child deserves to be heard.
Questions parents ask
The questions we hear most about apraxia
CAS is a motor planning disorder, not a timetable problem, and it doesn't typically resolve by waiting. The encouraging flip side: it responds to the right kind of therapy at the right frequency. The children who tend to do best are the ones whose apraxia was identified accurately and treated with motor-learning approaches, early and often.
No, and this matters. ASHA is explicit that mouth muscles are not weak in children with CAS, which is why blowing, chewing and strengthening exercises are not the treatment. The problem is the brain's plan, not the muscle's power. So therapy practices actual speech movements, over and over, with cues that help the plan stick.
Because this differential is honestly hard. The conditions share features, there's no single definitive test, and even experienced clinicians weigh the markers differently. A motor-speech-focused evaluation looks specifically at inconsistency, transitions and prosody across structured tasks. With very young children, sometimes the honest answer is “let's treat, watch and confirm.” The picture usually clarifies with time and therapy.
We won't promise timelines; anyone who does isn't being straight with you. What we can say honestly: with accurate diagnosis, frequent motor-based therapy and home practice, children with CAS make real progress, and many go on to be understood by most people. AAC along the way protects communication and confidence while the speech system is built. This is a marathon with mile markers, and we celebrate every one.
