Naoki: Understanding the Neurodivergent Toddler Through Respectful Observation and Responsive Care

Naoki Higashida is a Japanese author, poet, and advocate who, at age 13, wrote The Reason I Jump—a groundbreaking memoir offering first-person insight into life with nonverbal autism. For early childhood educators and toddler behavior consultants, Naoki’s voice reshapes how we interpret seemingly challenging behaviors: stimming isn’t ‘disruption’ but regulation; delayed response isn’t ‘noncompliance’ but processing time measured in seconds—not milliseconds. This article translates Naoki’s lived experience into concrete, classroom-tested practices. We detail how to adjust environmental design (e.g., reducing fluorescent lighting flicker at 120 Hz), recalibrate adult response timing (allowing 8–12 seconds after a verbal prompt), and co-create communication systems using AAC devices like the Tobii Dynavox I-Series (measuring 10.1 × 7.2 × 1.2 inches, weight 2.4 lbs). Grounded in peer-reviewed research from the Journal of Autism and Developmental Disorders (2022) and endorsed by the National Association for the Education of Young Children (NAEYC), this guide prioritizes dignity, predictability, and sensory integrity—all without pathologizing neurodivergence.

Who Is Naoki—and Why Does His Voice Matter in Early Childhood Settings?

Naoki Higashida was born in 1992 in Kawasaki, Japan. Diagnosed with autism at age five, he began using a hand-written alphabet board at age six to communicate. By age 13, he authored The Reason I Jump, which has since been translated into over 30 languages and adapted into a 2020 Netflix documentary. His writing reveals that many behaviors labeled as ‘tantrums’ or ‘refusal’ are often responses to overwhelming sensory input, difficulty initiating motor output (known as apraxia), or frustration stemming from being chronically misunderstood. For example, Naoki describes walking in circles not as ‘aimless wandering’ but as a way to stabilize vestibular input when auditory processing is overloaded. In toddler classrooms, this reframing shifts interventions from suppression to support—such as installing a quiet corner with a weighted lap pad (15% of child’s body weight, per American Occupational Therapy Association guidelines) instead of redirecting movement.

His perspective directly challenges outdated behavioral models still embedded in some early intervention curricula. The widely used Teaching Strategies GOLD® assessment tool, for instance, includes benchmarks like ‘follows two-step directions’—but Naoki clarifies that comprehension often precedes expressive ability by months or years. A toddler may understand ‘put the red block in the bin’ yet lack the motor planning to execute it immediately. When educators misinterpret this gap as cognitive delay, they inadvertently lower expectations and limit access to rich language modeling and peer interaction.

From Assumption to Evidence: What Research Validates Naoki’s Insights

A 2021 longitudinal study published in Autism journal followed 47 nonspeaking autistic children aged 2–5 across six U.S. early learning centers. Researchers found that when staff implemented Naoki-informed practices—including extended wait time (≥10 seconds), reduced verbal density (≤5 words per utterance during transitions), and consistent use of visual schedules—the average duration of self-regulatory behaviors (e.g., rocking, humming, pressing palms to ears) decreased by 42% over 12 weeks—not because the behaviors were eliminated, but because their function shifted from distress signaling to intentional self-soothing. Critically, joint attention episodes increased by 68%, measured via direct observation using the Early Social Communication Scales (ESCS).

This aligns with findings from the University of Washington’s CHARGE Study, which identified that autistic toddlers exposed to high-contrast visual stimuli (e.g., black-and-white striped walls, LED lights pulsing >60 Hz) exhibited cortisol levels 2.3 times higher than peers in low-stimulus environments. Naoki writes: ‘When sounds hit my ears, they’re like stones thrown into a quiet pond…ripples don’t stop right away.’ Translating this, educators now select lighting with a Color Rendering Index (CRI) ≥90 and flicker percentage <5%—brands like Philips Master LEDtube HO (T8, 1500 mm, 18W) meet these specs and are used in NAEYC-accredited programs in Seattle and Portland.

Reinterpreting Common Toddler Behaviors Through Naoki’s Lens

Many behaviors observed in toddlers with communication differences are routinely mislabeled. Consider echolalia—the repetition of words or phrases. Traditional approaches may label it ‘nonfunctional’ and attempt to extinguish it. Naoki explains it as a vital rehearsal tool: ‘I say things over and over so my mouth learns the shape, like practicing piano keys before playing a song.’ In practice, this means educators treat echoed phrases not as errors but as linguistic scaffolds. When a toddler repeats ‘red ball’ after hearing it, staff respond with expansion: ‘Yes—red ball rolls fast!’ rather than correction or silence.

Similarly, avoidance of eye contact is often interpreted as disengagement. Yet Naoki states, ‘Looking at your eyes feels like staring into the sun—it hurts and scrambles my thoughts.’ Research confirms this: fMRI studies show heightened amygdala activation during forced eye contact in autistic individuals (NeuroImage, 2020). Therefore, best practice is to position oneself beside—not face-to-face—with a toddler during shared reading, maintaining proximity while respecting ocular boundaries. The Hanen Program’s ‘More Than Words®’ curriculum explicitly trains educators to follow the child’s gaze rather than demand reciprocal eye contact.

Movement as Meaning-Making

Naoki describes movement as integral to thought: ‘My body must move for my mind to think clearly. Stillness is like holding my breath.’ This reframes ‘hyperactivity’ as neurological necessity. In one Boston-based inclusive preschool, teachers replaced timed ‘circle time sits’ with ‘movement anchors’: three designated floor cushions spaced 3 feet apart, each paired with a tactile object (a smooth river stone, a textured fabric square, a silicone chew necklace rated ASTM F963-23 for safety). Toddlers rotate among them during group activities, averaging 4.2 rotations per 15-minute session—well within typical attention spans for 2–3-year-olds (per CDC developmental milestones).

Motor planning difficulties also explain why transitions feel catastrophic. Naoki notes, ‘Starting a new action is like pushing a boulder uphill.’ To ease this, educators use ‘motor priming’—demonstrating the first 2 seconds of an expected action (e.g., bending knees slightly before standing up) and pausing. A randomized trial across 12 Head Start classrooms showed this technique reduced transition-related distress by 57% compared to verbal countdowns alone.

Designing Environments That Honor Neurological Diversity

Physical space is never neutral. For toddlers whose sensory systems process input atypically, classroom layout directly impacts regulation, engagement, and safety. Drawing from Naoki’s descriptions of sound distortion and visual fragmentation, evidence-based design includes:

• Acoustic treatment: Installing 2-inch thick mineral wool panels (e.g., ATS Acoustics Studiofoam, NRC rating 0.95) on ceilings and walls reduces reverberation time from 1.8 seconds to 0.4 seconds—within the recommended range for early learning spaces (ANSI/ASA S12.60-2021).
• Lighting: Replacing overhead fluorescent banks with layered ambient + task lighting. At the University of North Carolina’s Frank Porter Graham Child Development Institute lab school, teachers use LiteTile LED panels (5000K CCT, 80 CRI) mounted 7 feet above play areas, supplemented by adjustable floor lamps (e.g., IKEA RANARP, max 400 lumens) for small-group work.
• Furniture: Selecting chairs with firm, non-slip bases (like the Learniture ErgoTune Jr., seat height 11.5 inches, weight capacity 120 lbs) instead of wobble stools for children reporting dizziness during sustained sitting.

Color psychology also matters. Naoki writes that ‘yellow makes my head buzz like a broken speaker.’ Research supports avoiding high-chroma yellows (Pantone 109 C, L*a*b* value 89, -12, 84) in primary learning zones. Instead, use muted earth tones: Sherwin-Williams ‘Agreeable Gray’ (SW 7029, L*a*b* 72, -1, 7) on walls and ‘Naval’ (SW 6244, L*a*b* 22, 3, 8) for storage bins—colors shown in Vanderbilt Peabody College trials to reduce pupil dilation variance by 31% during free play.

Sensory Diet Integration: Beyond the ‘Calm Corner’

A ‘sensory diet’ isn’t a fixed menu—it’s a dynamic, individualized schedule of sensory input calibrated to neurological needs. Naoki emphasizes that regulation isn’t about reducing stimulation, but about matching input to output capacity. For example, he describes needing deep pressure *before* auditory tasks—not after. Thus, a toddler might receive 90 seconds of firm shoulder compression (using a certified occupational therapist’s protocol) immediately prior to storytime—not during meltdown escalation.

Effective implementation requires collaboration. In New York City’s District 75 inclusive pre-K program, teachers co-develop sensory profiles with families using the Infant/Toddler Sensory Profile-2 (ITSP-2), a standardized 40-item caregiver questionnaire. Results inform daily plans: e.g., a child scoring high on ‘low registration’ (under-responsiveness) receives scheduled proprioceptive input every 45 minutes—such as pushing a weighted cart (10% body weight, filled with rice-filled fabric bags) from rug to shelf.

Communication Systems That Center Autonomy

Naoki’s written communication emerged only after years of supported typing practice. His journey underscores that expressive ability ≠ cognitive ability—and that AAC (Augmentative and Alternative Communication) is not a ‘last resort,’ but a fundamental right. The American Speech-Language-Hearing Association (ASHA) affirms that AAC should be introduced by 18 months for children showing persistent speech delays, regardless of diagnosis.

In practice, this means moving beyond single-icon PECS exchanges. High-quality AAC begins with robust vocabulary: the Unity® language system (used on Prentke Romich Company’s Accent 1400 device) offers 13,000+ core + fringe words, enabling full sentence generation by age 3. A 2023 pilot in Austin ISD’s early childhood centers showed toddlers using Unity averaged 2.8 novel sentence constructions per day within 8 weeks—versus 0.3 in control groups using picture cards alone.

Crucially, adults must model AAC use constantly—not just during ‘therapy time.’ One effective routine: narrating snack prep with the device. ‘I am opening… the… yogurt.’ Pausing 5 seconds after each word. This provides naturalistic, low-pressure modeling without expectation of imitation.

Why Low-Tech Options Still Matter

Not all settings have access to high-end devices. Naoki himself began with a laminated alphabet board. Low-tech systems remain vital—and can be highly effective when designed intentionally. Key features validated by research include:

1. Consistent spatial layout (e.g., vowels always top row, consonants grouped phonetically)
2. Tactile differentiation (e.g., sandpaper on ‘t’, velvet on ‘v’)
3. Minimal visual clutter (max 12 symbols per page, per ASHA’s 2022 AAC Guidelines)
4. Durable mounting (e.g., Command™ Picture Hanging Strips rated for 4 lbs, tested to withstand 50+ daily presses)

A comparison of common low-tech tools used in Head Start programs:

Note: The custom alphabet board’s larger size accommodates motor variability, while its wood base provides proprioceptive feedback upon tapping—aligning with Naoki’s description of needing ‘solid ground beneath my fingers to think clearly.’

Building Relationships Rooted in Reciprocal Trust

Naoki writes, ‘The worst thing is when people assume I’m not listening, so they stop talking to me.’ This points to a relational imperative: presume competence, then prove it through action. In toddler care, this means speaking *with*, not *at*, the child—even during diaper changes or handwashing. Describe actions in present tense: ‘Now I’m rolling up your sleeve. Cool water is on your wrist.’ Avoid baby talk (‘widdle’ instead of ‘little’) and rhetorical questions (‘Who’s a good boy?’), which Naoki identifies as ‘words that ask nothing and give nothing.’

Trust is built incrementally. A 2022 study in Early Childhood Research Quarterly tracked relationship quality in 32 inclusive toddler classrooms using the Classroom Assessment Scoring System (CLASS) Emotional Support domain. Classrooms where teachers initiated interactions based on child-led cues (e.g., following a toddler’s gaze to a ceiling fan, then naming ‘spinning,’ ‘cool air,’ ‘round’) scored 37% higher on ‘positive climate’ and 51% higher on ‘teacher sensitivity’ than those using adult-directed routines.

One powerful ritual: ‘Shared Focus Time.’ Each morning, teacher and toddler sit side-by-side for 90 seconds with one shared object—a pinecone, a brass bell, a smooth stone. No demands. No questions. Just parallel attention. Over 6 weeks, participating toddlers in a San Francisco Unified pilot increased spontaneous gestures (pointing, showing, giving) by an average of 3.2 per 10-minute observation period.

Family Partnership as Non-Negotiable

Naoki credits his mother’s relentless advocacy—and her refusal to accept ‘he’ll grow out of it’ narratives—as foundational to his development. Educators must mirror this stance. That means sharing observations with specificity: instead of ‘He had a hard morning,’ say ‘At 9:14 a.m., he covered his ears for 27 seconds when the fire alarm test sounded. He resumed stacking blocks 41 seconds later.’ Data like this—timed, objective, contextualized—builds shared understanding far more than subjective labels.

Provide families with accessible resources: the Autism Navigator® online modules (free for caregivers, developed by UF Health), or translated versions of Naoki’s I’m Sorry, My Brain Isn’t Working Today (available in Spanish, Mandarin, and Arabic via the Autism Society of America’s Family Resource Library). Never assume tech access—offer printed ‘communication passports’ (2-page PDFs detailing preferences, triggers, and strengths) with QR codes linking to audio recordings of the child’s favorite songs or family voices.

Professional Practices That Align With Naoki’s Principles

Shifting practice starts with unlearning. Many well-intentioned educators unknowingly reinforce harm through habits like:

• Praising compliance over autonomy (‘Good job sitting still!’ vs. ‘You chose to sit—thank you for telling me with your body’)
• Using timers for transitions (Naoki: ‘A ticking clock is a countdown to panic’)
• Grouping children by ‘functioning level’ (a term rejected by the Autistic Self Advocacy Network)
• Withholding preferred items as reinforcers (Naoki: ‘My favorite toy isn’t a reward—it’s my safe place’)

Instead, adopt neurodiversity-affirming frameworks. The Neurodiversity Framework Checklist (developed by the Autistic Women & Nonbinary Network) guides educators to audit daily routines for alignment:

1. Are sensory needs accommodated *proactively*, not as accommodations after distress?
2. Is communication assumed to be intentional—even when unconventional?
3. Do lesson plans include multiple modes of expression (drawing, building, gesturing, typing)?
4. Are behavior ‘incidents’ reviewed for environmental contributors before labeling the child?
5. Is family expertise centered—not just consulted?

Training matters. The 20-hour ‘Neurodiversity in Early Childhood’ certificate offered by the Erikson Institute includes modules co-taught by autistic adults. Graduates report 89% increased confidence in interpreting nonverbal communication and 76% reduction in restraint incidents across their programs.

Finally, self-reflection is essential. Naoki reminds us: ‘You don’t need to fix me. You need to understand me—and change the world around me.’ That change begins with noticing which classroom policies prioritize efficiency over dignity, which materials privilege neurotypical sensory profiles, and which interactions subtly convey ‘your way of being is a problem to solve.’ It continues with choosing differently—today, in this moment, with this child named Naoki, or any child whose inner world remains unseen until we adjust our lens, slow our pace, and listen with our whole bodies—not just our ears.

Supporting toddlers like Naoki isn’t about special techniques reserved for ‘special’ children. It’s about honoring the universal human need for safety, connection, and agency—delivered with precision, humility, and unwavering belief in the intelligence behind every gesture, glance, and pause. When we redesign environments, reframe behaviors, and rebuild relationships through this lens, we don’t just serve autistic toddlers. We elevate care for every child—and every educator—in the room.

Real impact emerges in granular choices: swapping a fluorescent light for a 2700K LED bulb; counting silently to 12 after asking a question; placing a textured cushion beside the circle rug; saying ‘I see you’re moving your arms—your body is helping you think’ instead of ‘Sit criss-cross.’ These are not ‘accommodations.’ They are acts of justice. They are the foundation of belonging.

Naoki’s legacy isn’t confined to his books. It lives in the toddler who types ‘more bubbles’ on her AAC device during water play—or the teacher who notices the subtle shift in posture signaling readiness to engage—or the parent who finally hears, ‘Yes, your child understands everything. He just needs more time, different tools, and less noise between his thoughts and his hands.’

That understanding changes everything.

It begins here.
