TL;DR
A child who can't tell you something hurts is a child whose ear infection can go untreated for a week. You can teach pain expression through visual pain scales, body maps, AAC devices, and steady modeling starting as early as 12 to 18 months. The approach shifts with language level, but the core stays constant: give the child a reliable tool, use it yourself first, and repeat until it sticks.
Why does teaching pain expression matter so much?
A child who can't tell you something hurts is a child whose ear infection goes untreated for a week. Or whose broken toe gets walked on. Or whose headache from a shunt malfunction gets read as a tantrum.
This is not hypothetical. Research in the journal Pain has found that children with intellectual disabilities and communication difficulties are more likely to have their pain underrecognized and undertreated than peers who can speak up for themselves [1]. The same pattern shows up in autism research. A 2020 study in the Journal of Pain reported that autistic people were more often undertreated for pain, partly because their behavioral signs of pain don't match what clinicians and caregivers expect to see [2].
So when a child melts down, bites themselves, refuses to walk, or falls apart out of nowhere, pain belongs on the list of suspects. Every time.
The fix is to build the communication bridge before the crisis, not during it. Teaching pain expression isn't a niche skill. It's basic safety.
What makes it hard for some kids to communicate pain?
Several things get in the way, and they tend to stack.
Language delays mean a child just doesn't have the words yet. If a two-year-old's expressive vocabulary is ten words, "hurt" or "owie" may not be among them, especially if nobody has made body-sensation words a priority [3].
Sensory processing differences change how some kids feel pain at all. Some autistic children have atypical pain sensitivity, higher or lower than average, so they may not show the classic cues a parent watches for [2]. That doesn't mean they can't learn to communicate about pain. It means you build the skill on purpose.
Motor speech disorders like apraxia of speech make words physically hard to produce even when the child knows them. A child with childhood apraxia of speech may understand exactly what "my tummy hurts" means and still not be able to say it reliably under the physical stress of actually hurting.
Some children lean on echolalia as their main way to communicate. They might repeat a memorized phrase that has nothing to do with pain, simply because they don't yet have a scripted line that fits. Seeing what echolalia means as a stage rather than a wall lets you work with it instead of against it.
History matters too. If a child has learned that expressing discomfort leads to forced procedures, restraint, or a panicked adult, they may shut those signals down entirely. Trust and a predictable response are part of the teaching, not separate from it.
At what age can you start teaching a child to express pain?
Earlier than most parents assume. Toddlers as young as 12 to 18 months can start learning basic body-part words and linking simple sounds or gestures to internal states when those ideas get modeled over and over [11]. You don't wait for sentences. You start with one word, a sign, a picture, or a symbol.
For infants and very young toddlers, the goal isn't self-report. It's sharpening your own read on behavioral pain cues (facial grimacing, leg guarding, the quality of the cry, how hard the child is to console) and narrating what you see out loud. "Oh, that hurt. Ouch." You're planting a vocabulary.
By 18 to 24 months, a typically developing child can point to a body part and use one word for a sensation. If your child is behind that, early intervention services can help you figure out where to begin. Most states run free evaluations for children under three through Part C of IDEA, the Individuals with Disabilities Education Act [5].
For older kids who are minimally verbal or who use AAC devices, there's no upper limit. The strategies below work whether your child is three or thirteen. Nobody ages out of learning to communicate about pain.
What tools actually work for teaching pain communication?
The honest answer: it depends on the child's language level. Here's the breakdown by level.
Pre-symbolic communicators (no consistent words or pointing yet)
Build one consistent pain signal. A gesture, a vocalization, a body movement that you all agree means "something is wrong." Some families use a hand-over-body gesture. Others use a specific high-pitched sound paired with an immediate, warm response. You're after signal reliability, not vocabulary.
The FLACC scale (Face, Legs, Activity, Cry, Consolability) was built for children who can't self-report. It's validated for kids from 2 months to 7 years, including those with cognitive impairment [6]. Print it. Keep it in the diaper bag or the medical binder so every caregiver reads pain through the same lens.
Emerging communicators (some words, signs, or symbols)
Add one or two core pain words to whatever system the child already uses. Picture exchange? Add a "hurt" card. Speech-generating device? Put "hurt," "owie," and key body parts on the home page, not three levels deep. ASHA's AAC guidance is blunt about this: frequently needed vocabulary should sit within one or two navigational steps [7].
Body maps earn their keep here. Print a simple front-and-back body outline. When something hurts, point to the spot. Laminate it. Keep copies in the car, the school bag, the doctor's office. Over a few weeks, pair the pointing with a spoken or device-generated word.
Kids with more language but shaky pain reporting
Visual pain scales work well. The Wong-Baker FACES Pain Rating Scale (six faces, smiling to crying) is validated for children as young as 3 and is free from the Wong-Baker FACES Foundation [8]. The Faces Pain Scale-Revised is another option, validated from age 4. Print both, try both, keep the one that clicks.
Role play matters more than most parents expect. Practice "what do you do when your tummy hurts?" during calm moments. The skill has to be rehearsed before it's needed, the way a fire drill happens before the fire.
How do AAC users learn to report pain?
AAC users hit a specific wall: the words they need have to already live in the device before the pain arrives. A child mid-crisis can't wait for you to hunt down a symbol. So the programming happens first, calm and ahead of time.
The practical steps:
1. Check the current AAC system right now. Is "hurt" reachable in one tap? Are basic body parts (head, stomach, ear, leg) in the vocabulary? If not, fix that before anything else on this list.
2. Model, model, model. Aided language stimulation means you use the device to talk too. Bump your knee, pick up the device, tap "hurt, leg." Child falls, tap "ouch, hurt" before you even ask them to. ASHA's guidance shows this kind of modeling raises functional AAC use [7].
3. Build routines around pain check-ins. Some families add a "how does your body feel?" question to the morning routine on the device, same time every day. When asking about pain is routine, answering stops feeling like a big deal.
4. Work with the child's speech therapist to program pain vocabulary and make a quick-access pain page. No SLP yet? Autism spectrum speech therapy programs often specialize in exactly this kind of functional mapping.
5. If in-person therapy is hard to reach, online speech therapy has grown a lot since 2020 and works well for AAC programming and parent coaching.
How do you teach body-part vocabulary as a foundation for pain reporting?
You can't report a stomach ache without knowing where the stomach is. Body-part vocabulary is the prerequisite, so it comes first.
Daily routines build it fastest. Bath time is ideal. Name body parts as you wash them, every time, no pressure. Dressing is another window. "Sock goes on your foot. Your foot." Little owies are the third: "You bumped your head. Your head hurts. Ouch."
For kids who learn through visuals, a labeled body chart on the bathroom wall gives dozens of low-pressure exposures a week. For kids who respond to songs, "Head, Shoulders, Knees, and Toes" is a real vocabulary tool, more than a way to pass the time.
Target these first: head, ear, eye, mouth, throat, tummy (or stomach), chest, back, arm, hand, leg, foot. Add "inside" (which a child can point to for internal pain) and "outside" once the concrete parts are solid.
If a child is slow to pick up body-part labels, raise it with an SLP. Trouble with body schema sometimes connects to proprioceptive processing differences, which an occupational therapist can assess.
What about kids who have high pain tolerance or seem not to feel pain?
Some children, particularly some autistic children, have genuinely altered pain sensitivity. The 2020 Journal of Pain study found real heterogeneity in autistic pain processing: some individuals show reduced behavioral responses even when physiological measures say pain is present [2].
That doesn't mean the child isn't hurting. It means behavioral cues alone will fail you.
For these kids, proactive check-ins matter even more. Build in a regular question: "Does anything hurt right now?" with a simple yes/no visual or a body map, at the same times each day. Before and after activities that tend to cause injury (sports, physical therapy, transitions across rough ground), add a quick body scan.
Tell the school team and medical providers about this profile straight out. Bring documentation. The AAP recommends that providers caring for autistic children stay aware of atypical pain presentation and ask structured questions rather than leaning on observation [4].
One more thing. Some children who read as pain-insensitive actually feel pain sharply but have learned not to show it, because past responses overwhelmed them. If you suspect that, work with a therapist who understands trauma and sensory processing alongside the SLP.
How should you respond when a child successfully communicates pain?
Your response decides whether they'll do it again.
Aim for calm, immediate, and validating. "Thank you for telling me. Let's look." That's it. No drama. No sprinting to the ER at the first "ouch," and no brushing it off either. The child learns that reporting pain brings a predictable, safe result: someone listens and helps.
For kids who have been through medical trauma, honesty goes in too. "I hear you. I'm going to look at your arm. It might feel a little cold when I touch it." Narrating your moves before you make them lowers the anxiety that often makes pain feel worse.
Don't accidentally punish the communication. If every "hurt" leads to a shot or an appointment that ends in restraint, the signal fades out. Work with your medical team on making visits more predictable and less frightening. The AAP has guidance on trauma-informed pediatric care that speaks to this directly [4].
And reinforce the act of telling you, more than the content of it. "I'm so glad you told me" is a short sentence that does heavy lifting.
How do you work with schools and caregivers on a shared pain communication system?
A child who uses a body map at home but gets nothing at school has a system that works maybe 40% of the waking day. That gap is where injuries hide.
You want one portable system every adult in the child's life knows how to use and answer. Write it into the IEP or 504 plan if the child has one. Under IDEA, communication goals, including medical and pain communication, can go straight into an IEP [5]. An SLP on the team should document the exact tools, vocabulary, and steps.
No IEP? A one-page communication passport does the job. It describes how the child communicates, what their pain signals look like, and what the adult should do. Most families can build one and hand it to teachers, coaches, grandparents, and babysitters.
Raise pain communication at every IEP meeting and every pediatric visit. Ask it plainly: "Is my child's ability to report pain documented in their care plan?" If the answer is no, that's your next item.
The Little Words app treats pain and body-state vocabulary as core targets. If you want a structured place to start daily practice, the quiz at littlewords.ai/start tells you which communication level to begin at and which words to prioritize first.
What does the research say about pain scales for kids who can't self-report?
There are validated tools, both observational and self-report, and the evidence behind them is reasonably solid.
For children who can't self-report, the FLACC scale has strong validation in post-operative and procedural pain, including in children with cognitive impairment [6]. You score each of five behavioral categories 0 to 2, for a total of 0 to 10. It's observer-rated, so a parent or nurse completes it, not the child.
For children who can self-report, starting around age 3 to 4, the Wong-Baker FACES Pain Rating Scale is one of the most studied pediatric pain tools going. It's been translated into more than 50 languages and used in hundreds of studies since the 1980s [8]. The Faces Pain Scale-Revised (FPS-R) is a validated alternative from age 4, free from the International Association for the Study of Pain [9]. The Numeric Rating Scale (0 to 10) becomes reliable around age 8 for most kids, earlier for some.
Nobody has great data on pain scale validity specifically for minimally verbal autistic children. The closest work suggests behavioral scales like FLACC stay the best available option, but they're imperfect, and caregiver report fills in context the scale misses [2].
The takeaway is simple: pick a validated scale, write down which one you chose, and use the same one every time so you can actually track change.
How do you practice pain communication without waiting for an emergency?
This is the part most families skip, and it's the part that decides everything.
Skills learned under stress are harder to reach than skills practiced calm. A child who has role-played "I have a tummy ache" thirty times over snack is far more likely to produce it during an actual stomach ache than a child who has only heard the words in theory.
Three practice structures that work:
Doll play. Practice on a stuffed animal or doll. "Oh, bear bumped his leg. What happened to bear? His leg hurts. Can you show me where?" Kids as young as two take to this, and it builds the words with zero physical discomfort.
Social stories. A short illustrated story (three to five pages, photos or simple drawings) about what happens when something hurts, read daily. "When my ear hurts, I touch my ear and say ouch. Then I show Mama. She looks at my ear. She says thank you for telling me." That gives the child a script before they need one.
Body check-ins. A quick daily question, "How does your body feel today?" with a visual scale or body map, makes talking about sensation ordinary. It also builds the habit of noticing and reporting instead of just reacting.
If your child has a behavior therapist, ask whether pain communication can go in as a functional communication training (FCT) goal. If they have an SLP, ask the same. It's a reasonable, evidence-aligned target for both.
When should you bring in a speech therapist for this specifically?
If your child is over 18 months and has no reliable way to tell you something hurts, that's a referral situation. Full stop.
ASHA defines functional communication as the ability to meet basic daily needs, and medical and safety communication sits near the top of that list [10]. An SLP can assess the child's current level, recommend the right AAC system or vocabulary set, and write goals that name pain and discomfort reporting directly.
If your child is already in speech therapy, bring up pain communication if it hasn't come up. It gets deprioritized sometimes, edged out by expressive vocabulary breadth or social language. You're allowed to say, "This is a priority for us, and I want it in the plan."
Early intervention through your state's Part C program is free for children under three, and SLPs in that system can target pain and safety vocabulary in the first years of life [12]. For children three and older, the school district must evaluate and serve the child under IDEA if they qualify [5]. If you're stuck on a waitlist or living somewhere rural, online speech therapy has grown fast and is covered by many insurance plans.
Don't wait on this one. Pain under-communication is a safety issue, and the earlier you build the skill, the more the child gets out of it.
Frequently asked questions
What is the best pain scale for a nonverbal child?
The FLACC scale (Face, Legs, Activity, Cry, Consolability) is the most validated observational pain tool for children who can't self-report, including those with cognitive or communication differences. It scores five behavioral categories from 0 to 2, giving a 0 to 10 total. It's observer-rated, so a parent or caregiver completes it. Print it, keep it in your child's medical folder, and use it consistently so you can track changes over time.
At what age should a child be able to say where it hurts?
Typically developing children begin pointing to body parts by 12 to 18 months and use one or two body-part words by 18 to 24 months. By age 3, most can name a body part that hurts and use a simple pain scale with adult support. If your child is well behind these markers, an early intervention evaluation is warranted. These timelines are guidelines, not verdicts. Many kids learn pain vocabulary later with the right support.
My autistic child doesn't seem to feel pain. How do I know if they're hurt?
Some autistic children have atypical pain responses, so signs like crying or guarding may be absent even when pain is present. Research in the Journal of Pain (2020) confirms this heterogeneity. Use the FLACC observational scale, do daily body check-ins with a visual tool, and tell all caregivers and providers about the pattern. If your child suddenly changes behavior, gets more dysregulated, or stops eating, pain is always worth ruling out.
How do I add pain vocabulary to my child's AAC device?
Make sure 'hurt' and 'owie' are reachable in one or two taps from the home page, not buried in a submenu. Add key body parts (head, ear, tummy, leg) at the same level. Then model the vocabulary yourself: whenever anyone gets hurt, tap the words on the device out loud. Work with the child's SLP to build a dedicated pain page with a body map icon if the device supports it. How often you model predicts how fast the child uses it.
Can I teach pain communication through play?
Yes, and it's one of the most effective methods. Doll or stuffed animal play lets children rehearse pain communication without physical discomfort. Say 'bear hurt his tummy, where does it hurt?' and guide the child to point or use a symbol. Social stories, a short illustrated narrative about what happens when something hurts and who helps, build a script before the child needs it. Daily practice during calm moments makes the skill available during actual pain.
What should I do if my child uses self-injury to communicate pain?
Self-injurious behavior (SIB) is sometimes a communication act. Before targeting SIB as a behavior to reduce, rule out pain as an underlying cause and figure out what function the behavior serves. A functional behavior assessment with a BCBA and an SLP working together is the right starting point. Replacing SIB means giving the child a reliable, easier alternative that gets the same result. Never address SIB without first making sure the child has a working pain communication system.
How do I get the school to support pain communication?
If your child has an IEP, ask that pain and medical communication be written as a goal, or at minimum documented in the health section. Under IDEA, IEPs must address the child's communication needs in full, which includes safety communication. Bring a one-page communication passport describing your child's pain signals and tools. If the school uses a different AAC system than home, have both SLPs align the vocabulary so the child doesn't have to context-switch during an emergency.
Is the Wong-Baker FACES scale accurate for young children?
The Wong-Baker FACES Pain Rating Scale is validated for children from age 3 and is one of the most widely used pediatric pain tools in the world, available in over 50 languages. It asks children to point to a face that matches how much they hurt. It's reliable for children who understand the idea of rating, usually age 3 and up, though some kids confuse sad faces with tired faces. Pairing it with a body map improves accuracy.
My child has apraxia. How do they communicate pain if speech is unreliable?
Speech under physical stress, like actual pain, is often harder to produce for children with apraxia than speech during calm. That makes a multimodal system essential: a body map they can point to, an AAC device with one-tap pain vocabulary, or a consistent gesture. Work with the child's SLP to design a system that doesn't depend on spoken words in the moment. The pain communication plan should be an explicit part of the apraxia treatment goals.
What words should I teach first for pain communication?
Start with one high-value signal word: 'hurt' or 'owie.' Then add a pointing gesture or body map. Once those are solid, add body-part labels: ear, tummy, head, and leg cover the most common pediatric pain complaints. Add 'inside' and 'outside' once the concrete parts are secure. For children using AAC, these belong among the first 50 core vocabulary items. Keep the list short and use each word so often it becomes automatic.
How do I explain pain intensity to a child who doesn't understand numbers?
Skip numbers until around age 8. Use faces (Wong-Baker or FPS-R), objects of comparison ('is it a little hurt like a bug bite or a big hurt like a fall?'), or a simple three-level visual: small, medium, big. Some families use a thermometer graphic with colors. The key is using the same scale every time so the child learns each level through repetition. Calibrate by reflecting back: 'you said big hurt and then you cried a lot, that makes sense.'
Can a late talker still learn to report pain before they have full sentences?
Absolutely. Single words, pointing, gestures, picture symbols, and AAC systems all work. You don't need sentences to report pain. A child who taps a picture of an ear is communicating just as functionally as one who says 'my ear hurts.' The goal is a reliable, consistent system, not grammatical completeness. If your late talker has no pain communication system yet, that's the first vocabulary target to prioritize with your SLP.
What is a communication passport and should my child have one?
A communication passport is a one-page document (sometimes two) that describes how a child communicates, what their behavioral pain signals look like, what tools they use, and what adults should do in response. You share it with every caregiver, school staff member, and medical provider. For children who can't self-report or whose communication is atypical, it's a safety tool. Most SLPs can help you build one, or you can find free templates from AAC organizations and hospital systems online.
