A child who can't tell you something hurts is a child whose ear infection can go untreated for a week, whose broken toe gets walked on, whose headache from a shunt malfunction gets read as a tantrum. You can teach pain expression starting as early as 12 to 18 months, using visual pain scales, body maps, AAC devices, and steady modeling. The tools shift depending on how much language a child has, but the core idea stays the same: give the child one reliable way to signal pain, use that tool yourself first, and repeat it until it sticks.
Why this matters more than it seems
This isn't 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. This isn't a niche skill. It's basic safety.
Why some kids struggle to say what hurts
A few 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 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 rather than waiting for it to appear.
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 manage to say it under the physical stress of actually hurting.
Some children lean on echolalia as their main way to communicate, repeating a memorized phrase that has nothing to do with pain simply because they don't have a scripted line that fits yet. Understanding 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 aren't separate from the teaching, they're part of it.
When to start
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 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 vocabulary before it's needed.
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, and 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.
Tools that actually work, by language level
For children with no consistent words or pointing yet, build one signal and stick to it: a gesture, a vocalization, a body movement everyone agrees means "something is wrong." Some families use a hand-over-body gesture, others a specific high-pitched sound paired with an immediate, warm response. You're after reliability, not vocabulary. The FLACC scale (Face, Legs, Activity, Cry, Consolability) was built for exactly this group. It's validated for kids from 2 months to 7 years, including those with cognitive impairment [6]. Print it and keep it in the diaper bag or medical binder so every caregiver reads pain the same way.
Once a child has some words, signs, or symbols, add one or two pain words to whatever system they already use. If they use picture exchange, add a "hurt" card. If they use a 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 too. Print a simple front-and-back body outline, laminate it, keep copies in the car, the school bag, the doctor's office, and have the child point to the spot when something hurts. Over a few weeks, pair the pointing with a spoken or device-generated word.
For kids with more language but shaky pain reporting, visual pain scales do a lot of work. 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. Try both and keep whichever one clicks. Role play matters more than most parents expect too: practice "what do you do when your tummy hurts?" during calm moments, because the skill has to be rehearsed before it's needed, the way a fire drill happens before the fire.
Helping AAC users 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 has to happen first, calm and ahead of time.
Start by checking the current system. Is "hurt" reachable in one tap? Are basic body parts (head, stomach, ear, leg) in the vocabulary? If not, fix that before anything else. Then model constantly: aided language stimulation means you use the device to talk too, so if you bump your knee, pick up the device and tap "hurt, leg." If your child falls, tap "ouch, hurt" before you even ask them to. ASHA's guidance shows this kind of modeling raises functional AAC use [7].
It helps to build routines around pain check-ins, like adding a "how does your body feel?" question to the morning routine on the device, same time every day, so answering stops feeling like a big deal. Work with the child's speech therapist to program pain vocabulary and set up a quick-access pain page. If you don't have an SLP yet, autism spectrum speech therapy programs often specialize in exactly this kind of functional mapping, and 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.
Body-part words come first
You can't report a stomach ache without knowing where the stomach is, so body-part vocabulary is the prerequisite. 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 a 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, not just 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 if a child seems to feel little or no pain?
Some children, particularly some autistic children, have genuinely altered pain sensitivity. A 2020 Journal of Pain study found real differences in how autistic people process pain: some show reduced behavioral responses even when physiological measures say pain is present [2]. That doesn't mean the child isn't hurting. It means you can't rely on behavior alone to tell you.
For these kids, proactive check-ins matter even more. Build in a regular question, "Does anything hurt right now?", paired with a simple yes/no visual or a body map, at the same times each day. Add a quick body scan before and after activities that tend to cause injury: sports, physical therapy, walking across rough ground.
Tell the school team and medical providers about this profile directly, and 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 look pain-insensitive actually feel pain sharply but have learned not to show it, because past reactions overwhelmed them. If that sounds familiar, bring in a therapist who understands trauma and sensory processing alongside the SLP.
How should you respond when a child tells you something hurts?
Your response decides whether they do it again. Aim for calm, immediate, and validating: "Thank you for telling me. Let's look." That's it. 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've been through medical trauma, honesty matters 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.
Try not to accidentally punish the communication. If every "hurt" leads to a shot or an appointment that ends in restraint, the signal fades. 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 a lot of work.
Getting schools and caregivers on the same page
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 that every adult in the child's life knows how to use and answer, written 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], and 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 put one together 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 step.
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 around. 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 remain the best available option, but they're imperfect, and caregiver report fills in context the scale misses [2].
Pick a validated scale, write down which one you chose, and use the same one every time so you can actually track change.
Practicing pain communication before you need it
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.
Doll play works well: 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 help too: 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. And body check-ins, a quick daily question like "How does your body feel today?" with a visual scale or body map, make 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 thing. It's a reasonable, evidence-aligned target for both.
When to bring in a speech therapist for this
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 getting 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, for a total out of 10, and a parent or caregiver fills it out just by watching the child. Print a copy, keep it in your child's medical folder, and use it the same way every time so you can actually track changes over time.
At what age should a child be able to say where it hurts?
Typically developing children start 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 kids can name a body part that hurts and use a simple pain scale with some adult help. If your child is well behind these markers, it's worth getting an early intervention evaluation. Think of these ages as guidelines rather than deadlines: plenty of children pick up pain vocabulary later once they get 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 the usual signs, crying or guarding, may not show up even when they're genuinely in pain. Research in the Journal of Pain (2020) backs this up, showing real variation in how autistic kids process and display pain. Use the FLACC scale, run daily body check-ins with a visual tool, and make sure every caregiver and provider knows about this pattern. If your child suddenly seems more dysregulated, changes behavior, 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" sit one or two taps from the home page, not buried in a submenu, and put key body parts (head, ear, tummy, leg) at that same level. Then model it yourself: any time someone gets hurt, tap the words out loud on the device. Work with your child's SLP to build a dedicated pain page, with a body map icon if the device allows it. How often you model the words is what predicts how quickly your child starts using them.
Can I teach pain communication through play?
Yes, and it's one of the most effective ways to do it. Doll or stuffed animal play lets a child rehearse talking about pain without any actual discomfort involved. Try "bear hurt his tummy, where does it hurt?" and guide your child to point or use a symbol in response. Social stories, short illustrated narratives about what happens when something hurts and who helps, give the child a script before they ever need it. Practicing this daily during calm moments is what makes the skill available later, when it actually hurts.
What should I do if my child uses self-injury to communicate pain?
Self-injurious behavior is sometimes a way of communicating. Before treating it as a behavior to reduce, rule out pain as the underlying cause and figure out what function it's serving. A functional behavior assessment, with a BCBA and an SLP working together, is the right place to start. Replacing self-injury means giving your child a reliable, easier way to get the same result. Don't address the behavior itself until you're sure your child has a working system for communicating pain.
How do I get the school to support pain communication?
If your child has an IEP, ask for pain and medical communication to be written in as a goal, or at least documented in the health section. Under IDEA, IEPs are required to address a child's communication needs fully, and that includes safety communication. Bring in a one-page communication passport describing your child's pain signals and the tools they use. If the school uses a different AAC system than the one at home, get both SLPs to align the vocabulary so your child isn't switching systems mid-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 anywhere, available in over 50 languages. It works by asking a child to point to the face that matches how much they hurt, and it's reliable once a child understands the idea of rating something, usually from age 3 on, though some kids mix up sad faces with tired ones. Pairing it with a body map helps sharpen the accuracy.
My child has apraxia. How do they communicate pain if speech is unreliable?
Speech under physical stress, like real pain, is often harder for a child with apraxia to produce than speech during a calm moment. That's why a multimodal system matters: a body map to point to, an AAC device with one-tap pain words, or a consistent gesture. Work with your child's SLP to build something that doesn't rely on spoken words in the moment it's needed. Pain communication should be a stated part of the apraxia treatment goals, not an afterthought.
What words should I teach first for pain communication?
Start with one strong signal word, "hurt" or "owie," and pair it with a pointing gesture or body map. Once that's solid, add body-part labels: ear, tummy, head, and leg cover most pediatric pain complaints. Add "inside" and "outside" once the concrete parts are secure. For kids using AAC, these words belong among the first 50 core vocabulary items. Keep the list short and use each word often enough that 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), comparisons ("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 like a thermometer graphic with colors. What matters is using the same scale every time, so the child learns each level through repetition. You can calibrate by reflecting it 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 all work fine. 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 polish. If your late talker doesn't have a 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 (sometimes two-page) document describing 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 your child sees. For a child who can't self-report, or whose communication looks different from what people expect, it functions as a safety tool. Most SLPs can help you put one together, or you can find free templates from AAC organizations and hospital systems online.
