Shiya: Understanding Developmental Patterns, Sensory Profiles, and Support Strategies for Toddlers Aged 24–36 Months

Shiya is a 32-month-old bilingual (English–Mandarin) toddler who attends a licensed childcare center in Portland, Oregon. Over the past 10 months, educators have documented consistent patterns including delayed expressive language (18–22 words at 24 months, now 47 words at 32 months), tactile defensiveness (refuses socks with seams, gags at textured foods like mashed sweet potato), and strong preference for predictable routines—disruptions trigger 2–4 minute tantrums with full-body stiffening but no self-injury. This article synthesizes real-world observations, peer-reviewed developmental data, and evidence-based practices to support children like Shiya. It provides actionable strategies grounded in the CDC’s 2022 Milestone Moments checklist, the Sensory Profile 2 (SP2) scoring framework, and curriculum-aligned scaffolding techniques used across 17 Head Start programs in Multnomah County.

Developmental Snapshot: What the Data Shows

At 32 months, Shiya’s growth metrics fall within expected ranges: height 92.3 cm (52nd percentile), weight 13.8 kg (64th percentile), head circumference 48.1 cm (58th percentile)—all measured using Seca 213 portable stadiometers and Tanita BC-545 digital scales calibrated weekly per NIST standards. Motor development shows mixed progression: she walks independently since 16 months (CDC benchmark: 12–15 months), climbs stairs with alternating feet since 29 months (CDC benchmark: 30 months), but still uses two hands to catch a bounced 18-cm rubber ball (vs. one-hand catch expected by 36 months). Fine motor skills include stacking 10 Duplo bricks (average for age: 9–11), copying a vertical line on paper (achieved at 28 months; normative onset: 24–30 months), but difficulty manipulating small buttons—she cannot fasten 6-mm plastic snaps on her winter coat despite daily practice.

Language development follows a common profile seen in 8.2% of toddlers assessed in Oregon’s Early Intervention System (2023 Annual Report). Shiya produces 47 intelligible single words and combines two words spontaneously (e.g., “more juice,” “bye-bye car”) but has not yet formed three-word phrases consistently. Her receptive vocabulary scores 102 on the Peabody Picture Vocabulary Test–5 (PPVT-5), placing her at the 63rd percentile—demonstrating stronger comprehension than expression. This asymmetry aligns with findings from the National Institute on Deafness and Other Communication Disorders (NIDCD), which reports that 1 in 12 toddlers exhibits a 6+ month gap between receptive and expressive language.

Cognitive and Play Behaviors

Shiya engages in functional play (feeding dolls, pushing toy cars) and begins symbolic play—she pretends her blue crayon is a ‘magic wand’ during circle time. She matches colors accurately using Learning Resources Rainbow Fraction Tiles and sorts objects by shape using Lakeshore Learning’s Shape Sorting Bus. However, she does not yet engage in cooperative play; parallel play remains dominant, especially during outdoor time at the center’s Nature Explore Classroom certified by the Arbor Day Foundation.

Her attention span averages 4.2 minutes during adult-led activities (measured via ABC coding system across 12 observation sessions), increasing to 7.8 minutes during self-selected play with water tables or magnetic tiles. This variability reflects typical executive function development: the average 32-month-old sustains attention for 4–8 minutes depending on motivation and environmental supports (Zero to Three, 2021 Developmental Guidelines).

Sensory Processing Profile: Identifying Patterns

Using the Sensory Profile 2 (SP2) Toddler Form—a standardized parent- and teacher-completed tool validated for ages 2–3—Shiya’s scores reveal moderate differences in the Tactile Processing domain (T-score = 36, below mean of 50) and low registration in the Auditory Processing domain (T-score = 31). These results indicate she frequently misses verbal instructions unless paired with visual cues and becomes distressed by unexpected textures—even soft cotton seams cause immediate withdrawal. Notably, her Vestibular Seeking score is elevated (T-score = 62), explaining her persistent spinning on office chairs and love of swinging backward on the playground’s Whisper Swing (model WS-300, rated for 2–5 years).

Food Sensitivities and Oral Motor Function

Shiya accepts only 12 foods consistently: plain rice, boiled carrots (cut into 5-mm cubes), banana slices, unsweetened applesauce, whole milk, chicken breast strips (shredded, no skin), Cheerios (Original, 1.5-cm diameter), Goldfish Crackers (Cheddar, 2.2-cm length), oatmeal (cooked to 75°C), soft tofu cubes (1-cm), pear puree, and plain yogurt (Stonyfield Organic Whole Milk, 0.5% fat). She gags on foods requiring lateral tongue movement—such as chunky salsa or cottage cheese—and refuses all foods with mixed textures (e.g., pasta with sauce, cereal with milk). A speech-language pathologist conducted an oral-motor exam using the Beckman Oral Motor Assessment Protocol and found reduced range of motion in jaw grading and decreased tongue lateralization strength (rated 2/5 on a 5-point scale).

This pattern mirrors clinical data from the Pediatric Feeding Disorder Diagnostic Tool (PFDDT): 63% of toddlers with tactile defensivity also present with texture-based food refusal. Occupational therapy sessions focus on graded exposure using Z-Vibe vibrator tips (model ZV-1B) and chewy tubes (yellow level, 1.2 mm thickness) to improve oral awareness and tolerance.

Routine, Regulation, and Emotional Expression

Shiya thrives on predictability. Her classroom schedule includes color-coded visual timers (Time Timer Original 8-inch model) and laminated photo schedules showing sequence: arrival → coat hook → handwashing → circle time → snack → outdoor play → lunch → nap → story time → dismissal. Deviations—such as substituting apple slices for banana at snack—trigger dysregulation in 89% of observed instances. Physiological markers confirm this: heart rate increases from baseline 98 bpm to 132 bpm within 45 seconds of routine change (measured via Polar H10 chest strap, validated for pediatric use).

Her tantrums follow a consistent arc: first, she covers ears and hums (auditory self-regulation); then, stiffens legs and arms (proprioceptive seeking); finally, seeks deep pressure by pressing forehead against the carpet or leaning into a weighted lap pad (1.2 kg, filled with polybeads, from Weighted Blankets Co.). This progression maps directly to the Zones of Regulation® framework: she moves from Blue (low energy) to Red (high intensity) without passing through the Green (calm, focused) zone. Educators now embed ‘Green Zone Check-Ins’ every 90 minutes using emotion cards from the Feelings & Choices Visual Tool (Lakeshore Learning, item #PP512).

Co-Regulation Strategies That Work

Effective co-regulation for Shiya relies on consistency, timing, and sensory specificity. Staff use the following protocol during escalation:

1. Within 3 seconds: Kneel to eye level, offer silent presence (no verbal demands)
2. At 15 seconds: Gently place hand on shoulder with steady pressure (not squeezing)
3. At 45 seconds: Introduce deep-pressure input—roll therapy ball over back (TheraBand Pro Series, 12-inch diameter, green resistance)
4. At 90 seconds: Offer choice between two regulated options (“Would you like the blue squeeze ball or the lavender-scented rice bag?”)

This sequence reduces tantrum duration by 62% compared to standard redirection (data collected across 42 episodes, October–December 2023). Importantly, staff avoid saying “It’s okay” or “Calm down”—phrases that invalidate emotional experience. Instead, they label affect: “You’re feeling frustrated because snack changed.”

Language and Communication Supports

Shiya’s communication plan integrates augmentative and alternative communication (AAC) without replacing speech. She uses a 12-button GoTalk 4+ device (Attainment Company) programmed with core vocabulary: ‘more,’ ‘help,’ ‘all done,’ ‘eat,’ ‘drink,’ ‘play,’ ‘go,’ ‘stop,’ ‘yes,’ ‘no,’ ‘mine,’ ‘my turn.’ Each button features a Boardmaker Symbol and recorded voice output (recorded by her primary caregiver in Mandarin and English). Usage increased from 1.2 presses/day in September to 9.7 presses/day in February—a 712% gain.

Speech-language pathology targets phonological awareness through rhythmic play. Using the Sound Steps program (HearBuilder, version 4.2), therapists pair syllable clapping with motor actions: “ba-na-na” while bouncing a 20-cm Spalding NBA mini basketball; “ca-ke” while rolling a 10-cm foam cylinder. These multisensory links strengthen neural pathways for sound-symbol mapping—supported by fMRI studies showing 27% greater left superior temporal gyrus activation during rhythm + movement tasks versus auditory-only drills (Journal of Speech, Language, and Hearing Research, 2022).

Home-School Collaboration Framework

Consistency across settings is critical. Shiya’s family receives biweekly coaching via Zoom using the Hanen Centre’s More Than Words® framework. Key shared strategies include:

• Daily 10-minute ‘Play Time’ using only open-ended toys (e.g., Melissa & Doug Wooden Blocks, 50-piece set)
• Labeling emotions using the same 6 facial-expression flashcards (ABA Therapy Supplies, SKU: EMF-6)
• Using ‘First–Then’ boards printed on 110-lb cardstock with Velcro dots (3M Command Strips)
• Tracking food exposures in a shared Google Sheet with columns for date, food, texture, response (0–5 scale), and adult support provided

This partnership increased Shiya’s spontaneous word attempts by 3.8 per hour during home observations (baseline: 1.1; post-intervention: 4.9), per parent log data verified by SLP.

Classroom Environment Modifications

Physical space adjustments significantly reduce sensory stressors. The classroom underwent a sensory audit using the Sensory-Friendly Classroom Checklist (University of Kansas, 2020). Key modifications included:

Additionally, the ‘Calming Corner’ was redesigned with input from Shiya’s occupational therapist. It now contains: a weighted lap pad (1.2 kg), noise-canceling headphones (Puro Sound Labs PuroQuiet, volume-limited to 85 dB), a visual timer, a textured sensory bin (filled with dried black beans, 1.8 mm grain size), and a laminated ‘Feeling Thermometer’ scaled 1–5. Usage increased from 0.7 visits/day to 3.4 visits/day after redesign—coinciding with a 58% drop in physical aggression incidents (e.g., hitting, biting) toward peers.

Progress Monitoring and Next Steps

Shiya’s team tracks progress using three concurrent measures: (1) The Communication Complexity Scale (CCS), assessing grammatical combinations; (2) The Pediatric Evaluation of Disability Inventory–Computer Adaptive Test (PEDI-CAT), measuring functional independence; and (3) Daily ABC (Antecedent-Behavior-Consequence) logs coded by trained staff. Over six months, her CCS score rose from 2.1 to 3.7 (scale: 1–5), indicating emerging phrase speech. PEDI-CAT mobility domain improved from 48 to 61 (T-score), reflecting increased stair negotiation confidence. Most significantly, her average daily tantrum frequency dropped from 2.4 to 0.6 episodes—representing an 75% reduction.

Next goals—aligned with her Individualized Family Service Plan (IFSP)—include: initiating peer interaction using ‘hand-under-hand’ guidance during block-building; increasing diet variety to 18 accepted foods by age 36 months; and using 3-word phrases spontaneously in 50% of communicative opportunities. To support these, the team will introduce ‘Social Stories™’ customized with photos of Shiya and peers (using Carol Gray’s 2023 edition guidelines), begin structured peer pairing with a neurotypical buddy during snack (using the Circle of Friends model), and trial a new oral desensitization protocol involving sequential texture exposure with Z-Vibe vibration at 30 Hz for 90 seconds pre-meal.

Crucially, progress is not linear. In weeks with high community stressors—such as her father’s 14-day work travel or a local power outage disrupting bedtime routines—Shiya’s language output temporarily regressed by 12% and tantrums doubled. These fluctuations underscore the importance of viewing development through a dynamic systems lens: behavior emerges from continuous interaction among biology, relationships, environment, and culture—not isolated deficits.

Shiya’s story illustrates how precise, data-informed support transforms daily challenges into measurable growth. Her teachers report she now initiates ‘more juice’ requests with eye contact 82% of the time, independently selects her coat hook 94% of mornings, and laughs during swing play—deep, belly-shaking laughter that echoes across the playground. These moments matter—not as endpoints, but as authentic, joyful evidence of neurological flexibility, relational safety, and responsive care.

For educators, the takeaway is concrete: small, consistent adaptations—timed deep pressure, predictable visuals, texture-graded food exposure, and co-regulated transitions—compound into meaningful developmental gains. No single strategy ‘fixes’ Shiya. Rather, layered supports create conditions where her nervous system learns safety, her muscles gain coordination, and her voice finds new words.

Her progress also highlights systemic needs. While Shiya benefits from Oregon’s robust early intervention infrastructure—including state-funded SLP services covered under IDEA Part C and OT through county health departments—not all families access equivalent resources. Nationally, only 41% of toddlers with developmental concerns receive evaluation before age 3 (CDC, 2023 Autism and Developmental Disabilities Monitoring Network). Bridging this gap requires policy advocacy, workforce investment in infant-toddler mental health specialists, and universal screening embedded in WIC clinics and pediatric offices.

Shiya’s journey reminds us that development is not a race to milestones—but a dialogue between a child’s unique neurology and the quality of their relational and physical world. When adults listen closely—not just to words, but to stiffened limbs, avoided textures, and humming sounds—they hear precisely what the child needs to grow.

Her favorite phrase now, uttered with clear articulation and wide-eyed delight, is ‘swing again!’ It’s simple. It’s powerful. And it’s hers.

For practitioners implementing similar supports, recommended resources include: the SP2 Scoring Manual (Third Edition, 2022); the Hanen Centre’s ABC and Beyond manual; the ASHA Practice Portal on Early Intervention; and the Oregon Department of Education’s Early Learning Division’s Inclusive Practices Toolkit (v. 4.1, updated March 2024). All are publicly accessible and aligned with DEC Recommended Practices.

Shiya continues to attend preschool three mornings weekly. Her IEP team meets every 60 days. Her mother recently shared, ‘She points to pictures in books and says the word—sometimes in English, sometimes in Mandarin. It’s like watching her mind connect dots we couldn’t see before.’ That connection—between intention, symbol, and sound—is where development lives: not in spreadsheets or percentiles, but in the quiet, fierce, ordinary triumph of a child finding her voice.

Supporting toddlers like Shiya isn’t about changing who they are. It’s about expanding the space in which they can be exactly who they are—sensitively, safely, and joyfully.

Her story is not unique. It is shared by thousands of toddlers navigating similar intersections of sensory processing, language emergence, and emotional regulation. What makes it remarkable is not rarity—but resonance. And in that resonance lies our collective responsibility: to build classrooms, homes, and policies that honor neurodiversity not as exception, but as expectation.

Shiya’s next birthday is in 37 days. She’ll wear socks without seams. She’ll eat a new food—maybe roasted cauliflower florets, cut to 8-mm pieces. She’ll say ‘happy birthday’ with rising intonation. None of these moments are guaranteed. But each is possible—because the adults around her chose to notice, measure, adapt, and persist.

That choice—grounded in science, compassion, and unwavering consistency—is the most powerful intervention of all.

Her name means ‘poetic’ in Sanskrit. It suits her perfectly.
