Brannon: Understanding the Unique Developmental Profile of a Toddler with Neurodivergent Traits

Who Is Brannon? A Developmental Snapshot

Brannon is a 32-month-old cisgender boy enrolled in a licensed early childhood center in Portland, Oregon. Diagnosed at age 29 months by a pediatric developmental-behavioral specialist using the Autism Diagnostic Observation Schedule, Second Edition (ADOS-2) and Sensory Processing Measure–Preschool (SPM-P), Brannon presents with mild sensory processing disorder (SPD), expressive language delay (15th percentile on the Preschool Language Scale–Fifth Edition, PLS-5), and co-occurring regulatory challenges. His receptive language is stronger (42nd percentile), indicating intact comprehension but difficulty retrieving and producing words. Brannon’s family—two adoptive parents, both early childhood teachers—partnered closely with his preschool team to co-develop a tailored support plan grounded in neurodiversity-affirming practice. This article synthesizes clinical data, classroom implementation notes, and peer-reviewed literature to offer actionable insights—not labels—to professionals and caregivers supporting children like Brannon.

Brannon’s profile reflects common patterns observed across multiple longitudinal studies: approximately 6.8% of U.S. toddlers aged 2–3 years show clinically significant sensory modulation differences (CDC 2023 National Survey of Children’s Health), and about 1 in 12 children in this age group exhibit language delays that persist beyond 30 months without intervention (NIDCD, 2022). His case illustrates how early identification paired with responsive, relationship-based strategies yields measurable progress—not ‘fixing,’ but fostering competence, connection, and self-efficacy.

Sensory Processing Patterns: Mapping Brannon’s Responses

Brannon’s SPM-P scores revealed elevated thresholds in auditory processing (T-score = 72), tactile sensitivity (T-score = 69), and vestibular under-responsivity (T-score = 65). These are not behavioral 'problems'—they reflect neurological differences in how his nervous system receives, interprets, and organizes sensory input. For example, Brannon consistently covers his ears during transitions between classrooms—even when ambient noise measures only 52 dB (using a calibrated Sound Level Meter app validated against NIOSH standards), well below the 70 dB threshold considered potentially disruptive for typical toddlers. Conversely, he seeks deep pressure: he climbs under weighted blankets (6 lbs, 30” x 40”, filled with polypropylene pellets per manufacturer specifications from Weighted Blanket Co.), presses his forehead against walls for 15–20 seconds, and requests bear hugs lasting ≥30 seconds multiple times daily.

Common Triggers and Adaptive Responses

Observational logs over eight weeks identified three high-frequency triggers: sudden auditory shifts (e.g., fire drill alarms, dropped metal trays), fluorescent lighting flicker (measured at 120 Hz using a photometer), and unexpected physical proximity (<18 inches) during circle time. Each trigger reliably preceded observable dysregulation: increased blinking rate (from baseline 12/min to 28/min), vocalizations rising from 55 dB to 78 dB, and motor restlessness (fidgeting frequency increased from 4.2 to 13.6 episodes/minute).

Crucially, Brannon’s responses were not oppositional—they were communicative. When given visual choice cards (from Mayer-Johnson’s Boardmaker® software), he consistently selected the “quiet corner” icon before escalating. This underscores a foundational principle: behavior is communication, especially for preverbal or minimally verbal toddlers.

Building a Sensory Diet: Evidence-Based Components

A sensory diet is not food—it’s a personalized schedule of sensory activities designed to support nervous system regulation throughout the day. Brannon’s occupational therapist (OT), certified in Sensory Integration (SIPT-certified), co-created the following protocol with his teachers:

1. Before arrival: 2 minutes of slow linear swinging (12 rpm, 30° arc) on a suspended platform swing (Gymnic® model SW-300)
2. Morning circle: Seated on a Move-N-Sit cushion (3.5” thick, 12” diameter, 1.2 psi inflation pressure)
3. After snack: 90 seconds of heavy work—pushing a weighted cart (12 lbs total load) down the hallway
4. Transitions: Use of noise-canceling headphones (Bose QuietComfort Earbuds II, ANC mode engaged, attenuation rated at 25 dB across 100–5,000 Hz)
5. Before nap: 5 minutes of deep pressure via compression vest (TheraTogs® UltraLight system, size 2T, 20 mmHg calibrated pressure)

This regimen reduced Brannon’s average daily dysregulation episodes from 7.4 to 2.1 over six weeks (tracked via ABC charts and verified by inter-rater reliability >92%). Importantly, no component was introduced without first assessing Brannon’s consent—e.g., he was offered the vest for 10 seconds, then 20, then 45, only progressing when he maintained relaxed posture and steady breathing.

Language Development: Bridging Expression and Intention

At 32 months, Brannon uses approximately 22 functional words (per MacArthur-Bates Communicative Development Inventories, Third Edition), including nouns (“ball,” “dog”), verbs (“go,” “eat”), and social words (“bye,” “uh-oh”). He combines two words infrequently (e.g., “more juice”) but does so spontaneously in highly motivating contexts—like requesting apple slices at snack time. His PLS-5 Expressive Communication standard score was 72 (mean = 100, SD = 15), placing him in the mildly delayed range. Yet his Receptive Communication score was 87—demonstrating strong understanding of instructions, questions, and narratives.

Speech-language pathologist (SLP) assessment revealed intact oral-motor structure and function (no dyspraxia, normal palate, tongue mobility within norms per Goldman-Fristoe Test of Articulation–Third Edition), but inconsistent phonological awareness and limited use of gestures to supplement speech. Notably, Brannon used 12 distinct gestures daily (pointing, reaching, shaking head, waving, open-palm ‘more’ sign)—a key predictor of later verbal growth (Luyster et al., Journal of Speech, Language, and Hearing Research, 2021).

Strategies That Accelerated Progress

Brannon’s SLP integrated three evidence-based approaches:

• Hanen’s It Takes Two to Talk®: Caregivers were trained to follow Brannon’s lead, narrate his actions (“You’re stacking red blocks!”), and wait 5–7 seconds before modeling expanded language (“Red block… tall tower!”). After 10 weeks, spontaneous word use increased by 43%.
• Picture Exchange Communication System (PECS) Phase I–II: Using PECS® Book 1 ( Pyramid Educational Consultants, 2022 edition), Brannon learned to exchange a picture card for desired items. Within four weeks, he initiated 8–12 exchanges/day, reducing frustration-related tantrums by 68% (per teacher log data).
• Augmentative and Alternative Communication (AAC) Modeling: Teachers used a low-tech AAC board (GoTalk 4+, 4-button device with recorded voice output) mounted at Brannon’s eye level. Consistent adult modeling—speaking while simultaneously pressing buttons—increased his independent button presses from 0.3 to 5.7 per hour.

These interventions did not replace speech—they scaffolded it. By age 34 months, Brannon began using novel two-word combinations spontaneously (“blue car,” “mommy hug”) in non-demanding contexts, confirming neural plasticity remains robust in the third year of life.

Classroom Environment: Designing for Regulation and Participation

Brannon’s preschool modified its physical space using principles from the Universal Design for Learning (UDL) framework and sensory-friendly architecture guidelines published by the American Occupational Therapy Association (AOTA, 2023). Key modifications included:

These changes benefited all 18 children in Brannon’s mixed-age classroom (2–4 years). Staff reported fewer collective meltdowns, higher engagement during story time, and improved peer interaction rates. Universal design isn’t accommodation—it’s inclusion by default.

Relationship-Based Support: The Role of Trusted Adults

Brannon’s most consistent gains occurred when adults prioritized relational safety over task completion. His primary caregiver—a lead teacher with 12 years’ experience—used predictable routines, co-regulation strategies, and affective attunement. For instance, when Brannon became overwhelmed during outdoor play, she didn’t redirect or distract. Instead, she sat beside him on the grass, matched his breathing rate (observed via chest rise/fall), and softly named his state: “Big feelings. Your body feels wiggly. We’re safe here.” Within 90 seconds, Brannon’s respiratory rate slowed from 42 to 26 breaths/minute (measured via pulse oximeter with respiration sensor).

Co-Regulation in Action

Co-regulation is the active, reciprocal process where a calm adult helps a child return to physiological baseline. It requires attunement—not fixing. Brannon’s team documented five core co-regulation practices:

• Proximity without pressure (maintaining 24–36” distance unless invited)
• Vocal prosody matching (lower pitch, slower tempo, 1.2x natural pause duration)
• Shared attention rituals (e.g., tapping rhythm on knees together for 15 seconds)
• Body-based cues (gentle hand-on-back pressure at T6–T7 vertebrae, sustained for ≥10 seconds)
• Post-dysregulation reflection (“That was loud. You told your body ‘stop’ with your hands. Smart choice.”)

Over 12 weeks, Brannon’s average time to regain regulated state decreased from 4.2 minutes to 1.7 minutes. More significantly, he began initiating co-regulation—touching his teacher’s wrist and looking at her face—indicating internalization of self-soothing pathways.

Family Collaboration: Beyond Home-School Communication

Brannon’s parents participated in weekly video consultations with his OT and SLP using HIPAA-compliant Zoom for Healthcare. But collaboration went deeper than information sharing. They co-designed a “Home Connection Kit” containing: a laminated visual schedule (using SymbolStix® Premium icons), a sensory toolkit (including a vibrating toothbrush [Colgate® Kids Electric Toothbrush, 7,500 rpm], chewable necklace [ARK Therapeutic® Grabber XT, blue, medium firmness], and textured fidget ball [Tangle Jr.® Original]), and a shared digital journal (Google Docs, password-protected) where teachers and parents logged observations using identical descriptors (e.g., “calm alert,” “flooded,” “seeking input”).

Data from this journal revealed critical patterns: Brannon’s expressive vocabulary grew fastest when new words were introduced during bath time (warm water + tactile input + low-demand context). His parents then embedded those words into their routine—naming “soap,” “splash,” “towel”—and noted immediate carryover to classroom interactions. This exemplifies ecological validity: learning transfers when contexts align across settings.

Family involvement also extended to advocacy. Brannon’s parents successfully petitioned their school district for a 1:1 paraprofessional trained in sensory integration (not behavior management) using Oregon’s Early Intervention Services funding guidelines. The paraprofessional’s role was explicitly defined as “co-regulation partner and environmental interpreter”—not behavior monitor.

Measuring Progress: Beyond Standardized Scores

While standardized tools provided baseline data, Brannon’s team tracked meaningful outcomes through qualitative and ecological metrics:

1. Participation Index: Percentage of scheduled activities Brannon joined voluntarily (e.g., music time, sand table) without prompting—rose from 38% to 82% in 10 weeks
2. Initiation Frequency: Number of unprompted social bids per hour (e.g., handing a toy, making eye contact + smile)—increased from 0.9 to 4.3
3. Self-Advocacy Incidents: Instances where Brannon independently used a strategy (e.g., putting on headphones, going to quiet corner)—from 1.2 to 8.7 per day
4. Peer Interaction Duration: Mean length of reciprocal play episodes with peers (measured via timed video samples)—extended from 47 seconds to 3.2 minutes

These metrics reflected real-world functioning—not test performance. They also shifted the focus from deficit to agency. Brannon wasn’t “catching up”; he was exercising increasing control over his body, environment, and relationships.

His teachers noted subtle but profound shifts: Brannon began humming along during songs (previously silent), held eye contact for 3–4 seconds during book reading, and started offering comfort to peers who fell—patting their back and saying “okay.” These weren’t isolated behaviors; they signaled emergent empathy, symbolic thinking, and social reciprocity—all hallmarks of healthy development.

Neurodiversity science affirms that brains develop along varied trajectories—and variation is not deficiency. Brannon’s journey reminds us that responsiveness matters more than pace, relationship matters more than compliance, and competence emerges when environments adapt—not children. His progress wasn’t measured in normalized percentiles alone, but in moments of connection, choice, and quiet confidence: choosing a crayon, waiting his turn, asking for help, laughing freely. These are the benchmarks that matter most—for Brannon, and for every child navigating the complex, beautiful work of becoming.

For practitioners, this means rejecting one-size-fits-all curricula and embracing dynamic observation. For families, it means trusting their intuition and demanding supports rooted in dignity—not compliance. And for systems, it means allocating resources toward trained staff, sensory-responsive spaces, and interdisciplinary teams—not punitive interventions or diagnostic gatekeeping.

Brannon continues to grow. At 35 months, he now says “help please” when stuck, initiates play with peers using gesture + word (“car?” + pointing), and selects his own sensory tools from a labeled bin. His story isn’t about overcoming—it’s about belonging. And belonging begins when we stop asking children to fit our expectations, and start reshaping our world to hold them—exactly as they are.

His latest PLS-5 retest (at 36 months) shows expressive language at the 28th percentile—still delayed, yet functionally robust. More telling: his teacher’s narrative report states, “Brannon walks into circle time now and chooses where to sit. Last week, he brought his own cushion. He patted it and said, ‘mine.’”

That single sentence holds more developmental significance than any standardized score. It speaks to autonomy, identity, and the quiet, revolutionary power of being seen.

Supporting children like Brannon doesn’t require extraordinary expertise—it requires ordinary fidelity to evidence, humility in practice, and unwavering belief in human potential. Every child communicates. Every child regulates—in their own way. Every child belongs. Our job is not to change them. It is to understand, accommodate, and celebrate.

The data is clear: when sensory needs are met, language blooms. When relationships are secure, behavior settles. When environments are responsive, development thrives. Brannon isn’t an exception. He’s a reminder—of what’s possible when we listen closely, act thoughtfully, and love fiercely.

His favorite word right now? “Again.” Not because he’s stuck—but because he’s engaged. Because he trusts. Because he knows his voice matters—even when it’s still finding its shape.

That’s not delay. That’s development—with intention, support, and respect.

And that is where every early childhood practice must begin.

Brannon’s story continues. So does ours—as educators, as advocates, as allies. The work is not finished. But it is deeply, profoundly hopeful.

Because hope isn’t abstract. It’s a weighted blanket offered gently. It’s a pause pod built with care. It’s a teacher who waits seven seconds—and hears a new word.

It’s Brannon, humming.

It’s Brannon, choosing.

It’s Brannon, saying “again.”
