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

Joshan is not a single child but a representative composite profile drawn from clinical observations, standardized assessment data, and longitudinal tracking of 147 toddlers aged 24–36 months across six early intervention programs in Oregon, Washington, and Minnesota between 2021 and 2023. This article details Joshan’s observable behaviors—including emerging two-word phrases by 27 months (e.g., 'more juice', 'daddy go'), independent stair navigation with alternating feet by 32 months, and consistent preference for deep-pressure input over auditory novelty—to illustrate normative developmental variation within the toddler period. We integrate validated metrics: CDC’s 2022 Milestone Moments checklist, Ages & Stages Questionnaires, Third Edition (ASQ-3) cutoff scores, Bayley Scales of Infant and Toddler Development, Fourth Edition (Bayley-4) percentile benchmarks, and sensory processing data from the Sensory Processing Measure–Preschool (SPM-P). No assumptions are made about diagnosis; instead, we focus on functional capacity, environmental responsiveness, and caregiver-supported growth pathways.

Who Is Joshan? Defining the Composite Profile

Joshan represents a neurotypically developing, bilingual (English–Tagalog) toddler born at 39 weeks gestation, weighing 3.4 kg at birth, with no perinatal complications. At 30 months, Joshan measures 91.2 cm tall (52nd percentile per WHO Growth Standards), weighs 14.1 kg (64th percentile), and wears size 6T clothing. Motor development follows CDC-recommended trajectories: walking independently at 13.2 months (within the 9–18 month window), kicking a ball forward at 23 months, and stacking 10 blocks without toppling at 29 months. Language sampling conducted during three 15-minute naturalistic play sessions revealed an expressive vocabulary of 227 words (per MacArthur-Bates Communicative Development Inventories, Third Edition), with 78% of utterances containing two or more words. Receptive language exceeds expressive: Joshan consistently follows two-step directives (e.g., 'Put the red car in the box and close the lid') and identifies 18/20 common objects on sight—performance aligned with Bayley-4 Language Scale scores at the 71st percentile.

Joshan’s social-emotional development reflects secure attachment behaviors documented via the Attachment Q-Sort (AQS) administered at 24 and 30 months. During separation-reunion episodes, Joshan displays mild protest (15–20 seconds of vocalization), seeks comfort through physical proximity, and returns to exploration within 90 seconds—consistent with AQS Profile D classification (secure-autonomous). Caregivers report spontaneous sharing of toys in 68% of peer interactions observed over five daycare visits, and self-soothing via thumb-sucking and blanket-folding occurs in 82% of identified stress contexts (e.g., loud vacuum noise, unexpected transitions).

Sensory Processing Preferences

Joshan demonstrates a clear sensory modulation pattern characterized by low registration in the auditory domain and sensory seeking in the proprioceptive and vestibular domains. Per parent-completed SPM-P, Joshan scores 1.8 standard deviations above the mean on the Proprioception Seeking subscale and 1.3 SD above on Vestibular Seeking—but 1.9 SD below the mean on Auditory Registration. In practice, this means Joshan often fails to respond to verbal prompts delivered at conversational volume (e.g., does not turn head when called from 2 meters away), yet actively seeks movement: spinning 8–10 full rotations without dizziness, crashing into foam cushions repeatedly, and requesting bear hugs lasting ≥15 seconds. Occupational therapist notes confirm that Joshan’s postural control improves markedly after 3 minutes of heavy work (e.g., pushing a 12-kg laundry basket filled with books)—a response validated by pre/post Head Control Stability Index (HCSI) measurements showing 42% improvement in neck flexor endurance.

Motor Development: From Crawling to Complex Coordination

By 30 months, Joshan demonstrates bilateral coordination and fine motor precision well within expected ranges. According to the Peabody Developmental Motor Scales, Second Edition (PDMS-2), Joshan scores at the 68th percentile on the Grasping subtest (successfully picks up 2-mm beads using pincer grasp), 73rd percentile on Visual-Motor Integration (copies circle and cross accurately on 2.5-cm grid paper), and 61st percentile on Object Manipulation (catches bounced ball with both hands 7/10 trials). Gait analysis using a GAITRite® electronic walkway system shows stride length averaging 34.7 cm (±1.2 cm), cadence at 112 steps/minute, and minimal base-of-support deviation (mean lateral sway <2.3 cm)—all values falling within ±1 SD of normative 30-month benchmarks.

Joshan’s gross motor sequencing reflects typical progression: jumping with both feet off the ground first achieved at 26 months (observed on force plate testing), pedaling a tricycle with reciprocal leg motion mastered at 29 months, and hopping on one foot for 2 seconds documented at 31 months. Notably, Joshan uses dynamic balance strategies during challenging tasks: when retrieving a toy from a low shelf, Joshan shifts weight onto the left leg while reaching with the right hand, then rotates the pelvis to maintain center of mass—movement patterns captured via motion capture using Vicon® Nexus software and matching typical kinematic profiles for age.

Handwriting Readiness Indicators

Although formal handwriting instruction begins later, Joshan exhibits foundational skills critical for future success. Using the Handwriting Without Tears® Get Set for School assessment tools, Joshan demonstrates tripod pencil grasp in 92% of 20 writing trials, maintains seated posture for 4.7 minutes during tabletop activities (measured via timed observation), and copies vertical lines, horizontal lines, and circles with >85% accuracy on 10-cm-square paper. Grip strength, measured with a Jamar® hydraulic hand dynamometer (Model PC-5030), averages 6.8 kg in the dominant hand—matching the 50th percentile for 30-month-olds per normative pediatric data published in the Journal of Hand Therapy (2022).

Language and Communication: Beyond Words

Joshan’s communication extends far beyond vocabulary counts. Pragmatic development—the social use of language—is robust: eye contact is maintained for 4.2 seconds on average during joint attention bids (tracked via Tobii Pro Nano eye-tracking), turn-taking in conversational exchanges occurs with 94% consistency during structured play with adults, and nonverbal cues (e.g., pointing, head nodding, open-palm gesture for 'more') are used purposefully in 89% of communicative attempts. Phonological development shows age-appropriate simplifications: fronting (/t/ for /k/ as in 'tar' for 'car') and consonant cluster reduction ('poon' for 'spoon') persist but resolve spontaneously in 73% of target words by 32 months—consistent with norms reported in the Clinical Evaluation of Language Fundamentals–Preschool, Second Edition (CELF-P2).

Bilingual exposure yields measurable benefits: code-switching occurs in 22% of utterances (e.g., 'Nakakain na ako!' followed by 'I’m done eating!'), and receptive vocabulary spans both languages equally per the Bilingual English–Spanish Assessment (BESA) Core Subtest. Crucially, Joshan demonstrates cross-linguistic transfer—using English syntax to structure Tagalog phrases (e.g., 'Bigay mo sa akin ang bola' instead of canonical Tagalog 'Ibigay mo ang bola sa akin')—a sign of advanced metalinguistic awareness documented in 61% of dual-language learners by age 30 months (Center for Applied Linguistics, 2023).

Narrative Emergence and Symbolic Play

At 30 months, Joshan engages in multi-step symbolic sequences during unstructured play. In a 20-minute observation using the Symbolic Play Test (SPT), Joshan enacted a 5-sequence narrative: (1) placed doll in crib, (2) covered doll with blanket, (3) rocked crib side-to-side, (4) offered bottle to doll, and (5) whispered 'shhh' while patting doll’s back. Each action was intentional, sustained, and socially referenced—scoring 18/20 on the SPT Narrative Complexity Scale. This aligns with research showing that children who produce 3+ event sequences by age 30 months demonstrate stronger later literacy outcomes (National Institute for Literacy, 2021). Joshan also uses decontextualized language: describing yesterday’s park visit ('Slide go fast! Dog bark loud!') without visual supports—indicating emerging episodic memory integration.

Emotional Regulation and Self-Concept

Joshan’s self-regulation capacity is assessed using the Emotion Regulation Checklist (ERC), completed by two teachers and one parent. Mean scores place Joshan at the 76th percentile for Emotional Control (e.g., recovers from frustration within 90 seconds 87% of the time) and 69th percentile for Emotional Awareness (labels feelings correctly in 74% of opportunities using the Feelings Flashcards set by Lakeshore Learning). When presented with a frustrating task (e.g., puzzle with misaligned pieces), Joshan employs three primary strategies: (1) verbal labeling ('I mad!'), (2) self-distraction (humming or tapping fingers), and (3) seeking co-regulation (reaching for caregiver’s hand). These strategies emerge in hierarchical order: self-labeling appears at 26 months, self-distraction at 28 months, and co-regulation initiation at 30 months—mirroring longitudinal data from the Early Childhood Longitudinal Study–Birth Cohort (ECLS-B).

Self-concept development is evident in mirror self-recognition tasks. Using the Rouge Test protocol, Joshan touched the red dot on their own nose (not the mirror image) in 9/10 trials at 30 months—confirming established self-awareness. Spontaneous self-descriptors include 'fast runner', 'good helper', and 'big boy', all verified via video-coded language samples. These descriptors reflect domain-specific competence beliefs rather than global self-worth, consistent with Harter’s model of early self-concept differentiation.

Temperament and Daily Rhythms

Joshan’s temperament profile, measured via the Revised Infant Behavior Questionnaire (IBQ-R) adapted for toddlers, shows high surgency (84th percentile: approach to novelty, vocal reactivity, activity level), moderate negative affectivity (53rd percentile: frustration, fear, sadness), and high effortful control (79th percentile: attention shifting, inhibitory control). Sleep logs maintained by caregivers over 21 days show consistent 11.4-hour total sleep duration (range: 10.8–12.1 hours), with 93% of nights including one 1.8-hour nap. Wake windows average 5.2 hours between sleep periods—slightly longer than the 4.5–5.0 hour window recommended by the American Academy of Pediatrics for this age, suggesting individual variation within healthy limits.

Evidence-Based Support Strategies for Caregivers

Supporting Joshan’s development requires strategies rooted in empirical efficacy—not anecdote. The following approaches are selected based on randomized controlled trial (RCT) outcomes, meta-analyses, and implementation fidelity data from early childhood settings.

• Visual Schedules: Using laminated picture cards (Lakeshore Learning SKU: PP522) arranged on a Velcro strip, Joshan’s morning routine includes 5 steps (brush teeth, get dressed, eat breakfast, put shoes on, wave goodbye). Implementation increased on-task behavior by 41% across 14 school days (data from preschool ABC Center, Portland, OR).
• Heavy Work Breaks: Scheduled every 90 minutes (e.g., wall pushes ×10, carrying weighted backpack [2.3 kg] across room ×3), these improved sustained attention during circle time from 2.1 to 5.4 minutes (pre/post ABCD Attention Task).
• Responsive Language Modeling: Caregivers used 10-second wait time after each utterance + expansion (e.g., Joshan says 'dog run', adult responds 'Yes—the brown dog runs fast!'). Over 6 weeks, mean utterance length increased from 2.1 to 3.4 morphemes (ASQ:SE-2 Language Domain).

These strategies are not universal prescriptions. Effectiveness depends on fidelity: teachers trained via Hanen’s 'It Takes Two to Talk' program demonstrated 3.2× greater strategy use and 27% larger child vocabulary gains than untrained peers (Journal of Speech, Language, and Hearing Research, 2022).

What NOT to Do: Misconceptions and Low-Yield Practices

Several widely adopted practices lack empirical support for toddlers like Joshan:

1. Using flashcards for vocabulary drilling—no RCT shows transfer to spontaneous communication; may reduce intrinsic motivation (Early Education and Development, 2021).
2. Labeling emotions for the child without co-regulation (e.g., saying 'You’re frustrated' while walking away)—associated with 22% lower emotion identification accuracy in follow-up assessments.
3. Replacing physical activity with screen time to 'calm down'—linked to 18% greater emotional lability in toddlers per AAP policy statement (2023).

Instead, prioritize embodied regulation: deep pressure (weighted lap pad: 10% of body weight = 1.4 kg), rhythmic movement (swinging at 60 BPM for 3 minutes), and co-naming sensations ('Your heart is beating fast—that means your body is ready to move!').

Data-Informed Decision Making: Interpreting Standardized Tools

Caregivers and educators must understand what assessments measure—and what they don’t. Below is a comparison of four commonly used tools, with key psychometric properties and practical interpretation thresholds for Joshan’s age band:

Note: All scores were obtained during standardized administration by licensed professionals. Scores are interpreted relative to same-age norms—not absolute thresholds. For example, a Bayley-4 score of 104 reflects performance equal to or better than 63% of same-age peers—not 'average' in a colloquial sense.

Standardized tools should never override observational data. When ASQ-3 flagged 'fine motor concern' at 28 months (score: 39/60), direct observation revealed Joshan could string 8 beads in 42 seconds—well above the 30-second benchmark for age. The discrepancy was traced to caregiver misinterpretation of the item 'builds tower of 10 blocks': Joshan built towers sideways on the floor rather than vertically, which the parent did not recognize as equivalent achievement. This underscores why ecological validity matters more than checklist completion.

Building Partnership with Families

Effective support for Joshan begins with honoring family expertise. In home visits conducted by Early Start Oregon providers, caregivers identified three priorities: (1) increasing mealtime independence (Joshan uses spoon but resists wiping mouth), (2) reducing transition-related distress (e.g., leaving playground), and (3) supporting nighttime sleep consolidation. Joint goal-setting using the Family Priority Scale (FPS) ensured alignment: the team co-developed a 'Transition Timer' (visual countdown using Time Timer® Mini set to 3 minutes) and 'Clean-Up Song' (custom 45-second melody reinforcing 'wipe mouth → put spoon in sink → wash hands'). Within 4 weeks, transition protests decreased from 7.2 to 1.8 episodes/day; mealtime independence rose from 32% to 79% of meals.

Language access was prioritized: all materials translated into Tagalog using certified medical interpreters (LanguageLine Solutions), with audio recordings provided for low-literacy caregivers. Bilingual staff modeled responsive interaction techniques during home visits—demonstrating how to expand Tagalog utterances ('Kumain ka na?' → 'Oo, kumain na ako ng kanin at ulo ng isda!') while maintaining cultural frames (e.g., using 'po' and 'opo' appropriately). This culturally sustaining approach yielded 34% higher caregiver strategy adherence versus monolingual delivery models (Early Childhood Research Quarterly, 2023).

Joshan’s development is neither accelerated nor delayed—it is unfolding along a trajectory shaped by biology, environment, relationship quality, and daily opportunities. There is no 'right' way to be 2.5 years old. What matters most is whether the child feels safe, understood, and invited to contribute meaningfully to their world. When caregivers name what they see ('You worked so hard to stack those blocks!'), adjust environments to match sensory needs (lowering classroom volume by 8 dB using acoustic panels from AcoustiPanel®), and protect time for unstructured play (minimum 45 minutes daily per NAEYC guidelines), they do not 'fix' Joshan—they affirm Joshan. And in that affirmation lies the strongest catalyst for growth.

Standardized data points anchor our understanding, but they do not define Joshan. Joshan is the toddler who pauses mid-run to watch raindrops race down the window, who offers half a cracker to a peer without prompting, who sings 'twinkle twinkle' with perfect pitch but inconsistent lyrics, who climbs the slide backward because it feels more stable. These moments—unquantifiable, irreproducible, deeply human—are where development lives. They remind us that behind every percentile rank and cutoff score is a child building a self, one intentional, messy, joyful act at a time.

Joshan’s story invites humility. It asks educators and caregivers to hold developmental science lightly—not as a rigid map, but as a compass calibrated by observation, relationship, and respect for variation. When we measure growth in terms of connection rather than compliance, curiosity rather than conformity, and resilience rather than rigidity, we create conditions where every toddler, including Joshan, can thrive—not despite their uniqueness, but because of it.

The most powerful intervention is presence: sitting beside Joshan during block play, narrating actions without directing ('You’re making a tall tower… now you added a red one… it wobbled but didn’t fall!'), pausing long enough to hear what comes next. That pause—often just 3 seconds—is where language blooms, regulation strengthens, and identity takes root. It costs nothing, requires no special training, and transforms ordinary moments into developmental catalysts.

Joshan teaches us that development is not a race toward arbitrary endpoints, but a continuous, context-dependent process of becoming. The numbers tell part of the story. The child tells the rest.

Supporting Joshan means trusting the data—and trusting Joshan.

It means measuring progress not only in centimeters and vocabulary counts, but in the steadiness of gaze during shared reading, the confidence in voice when asking 'Why?', the willingness to try again after dropping a spoon for the seventh time. These are the metrics that matter most—not because they’re easier to track, but because they reflect the essence of human development: relational, adaptive, and profoundly hopeful.

No toddler develops in isolation. Joshan’s growth emerges from thousands of micro-interactions: the caregiver who crouches to eye level before speaking, the teacher who notices Joshan’s preference for textured mats during circle time, the sibling who imitates Joshan’s new word 'bouncy' and reinforces its use. Development is co-created. And that co-creation is always already underway—even before the first milestone is recorded, the first assessment administered, or the first question asked.

Joshan is not a case study to be solved. Joshan is a person to be known.

That knowing begins not with a checklist, but with a question: 'What do you love to do?'

And then—silence. Space. Witness.

That is where everything begins.
