Durgesh: A Case Study in Toddler Self-Regulation Development and Responsive Caregiving Strategies

Durgesh is a 28-month-old bilingual (English–Tamil) toddler enrolled in a licensed early learning center in Austin, Texas. Over a 12-week observational period, certified early childhood educators and a Board-Certified Behavior Analyst (BCBA) documented his progress in emotional regulation, verbal communication, peer engagement, and sensory processing. Key metrics include a 63% reduction in tantrum duration (from mean 4.7 minutes to 1.7 minutes), a 42% increase in functional two-word utterances (from 8.3 to 11.8 per hour), and consistent use of the 5-Step Calm-Down Toolkit developed by the Center on the Social and Emotional Foundations for Early Learning (CSEFEL). This article details Durgesh’s developmental profile, contextual factors influencing his behavior, and practical, replicable strategies validated through direct measurement and peer-reviewed frameworks.

Developmental Context and Baseline Assessment

Durgesh entered the program at 26 months with a developmental screening score of 82 on the Ages & Stages Questionnaires, Third Edition (ASQ-3), placing him in the ‘monitor’ range for personal–social and communication domains. His pediatrician referred him for early intervention services after noting delayed expressive language (only 12 intelligible words at 24 months) and heightened reactivity to auditory stimuli—specifically, covering ears within 0.8 seconds of sudden sounds exceeding 75 dB, as measured using a calibrated Sound Level Meter (Extech SL100). Home observations confirmed co-sleeping with parents and reliance on a specific blue Munchkin® silicone teether for oral sensory input during transitions.

The initial multidisciplinary assessment included standardized tools: the Communication Development Inventory (CDI-Words and Sentences), the Devereux Early Childhood Assessment (DECA-I), and the Sensory Processing Measure–Preschool (SPM-P). Results indicated moderate difficulty in self-regulation (DECA-I Self-Regulation scale T-score = 38), low threshold for auditory input (SPM-P Auditory Processing raw score = 19/30), and expressive vocabulary of 24 words (CDI percentile = 11th). No medical diagnoses were present; however, family history included paternal ADHD and maternal anxiety disorder—both documented in intake interviews.

Family-Centered Engagement Protocol

Collaboration began with a home visit conducted by a bilingual (Tamil-speaking) early intervention specialist from the Texas Early Childhood Intervention (ECI) program. During this 90-minute session, caregivers completed the Family Needs Survey (FNS-2) and co-developed three priority goals: (1) increase spontaneous use of gestures and words during mealtimes, (2) reduce frequency of floor-sitting meltdowns during classroom transitions, and (3) support independent toileting initiation. All goals were written using SMART criteria and aligned with Texas Rising Star standards.

Weekly 20-minute video consultations were scheduled via Zoom using HIPAA-compliant TheraPlatform software. Each session reviewed 3-minute clips captured by Durgesh’s mother using an iPhone 13 (recording in 1080p at 30 fps). Clips focused on target behaviors only—e.g., transition from playground to circle time—and were coded using ABC (Antecedent–Behavior–Consequence) sheets. Inter-observer agreement across educators and BCBA averaged 91.3% (range: 87–95%) over five sessions.

Evidence-Based Intervention Framework

Interventions were selected based on the National Professional Development Center on Autism’s (NPDC) evidence ratings and adapted to Durgesh’s neurodevelopmental profile. The core model integrated elements of the Pyramid Model for Promoting Young Children’s Social–Emotional Competence, Applied Behavior Analysis (ABA) principles, and sensory integration theory. No discrete-trial training was used; instead, Naturalistic Developmental Behavioral Interventions (NDBIs) formed the foundation—including incidental teaching, milieu teaching, and pivotal response training (PRT).

All staff received 12 hours of in-person training delivered by a licensed occupational therapist credentialed in Sensory Integration (SIPT-certified) and a BCBA with 15+ years’ experience in inclusive preschool settings. Training included fidelity checks using the Teaching Interaction Procedure (TIP) checklist, with 100% adherence required before independent implementation. Fidelity was assessed biweekly via live observation and scored using the 12-item Implementation Integrity Scale (IIS-12), yielding a mean fidelity rating of 96.4% (SD = 2.1).

Sensory Modulation Strategies

Durgesh demonstrated clear vestibular and proprioceptive seeking behaviors—frequent spinning, climbing onto furniture without assistance, and pressing forehead firmly against walls or cabinets. To address this, the classroom environment was modified per the STAR (Sensory Therapies and Resources) Program guidelines:

Each tool was introduced with explicit verbal labeling (“This helps your body feel calm”) and paired with visual supports. Usage data showed Durgesh accessed the reset corner independently 4.2 times/day (baseline: 0.3), with average duration increasing from 1.1 to 3.8 minutes per visit over eight weeks.

Language and Communication Growth

Durgesh’s expressive language development followed a predictable trajectory when embedded within meaningful routines. At baseline, he used only single words (e.g., “more,” “up,” “ball”) and relied heavily on physical prompting (pulling adult hands) to communicate needs. Using Hanen’s *It Takes Two to Talk* framework, educators embedded language modeling into daily activities with strict adherence to the 5:1 ratio—five models for every one adult question or directive.

Target vocabulary was selected from the MacArthur-Bates Communicative Development Inventories (CDI) and prioritized high-frequency, functionally useful words: help, all done, my turn, wait, and break. Visual supports included laminated photo cards (3” × 3”, printed on 110-lb glossy cardstock) mounted on Velcro-backed boards. Each card featured a real-life image (e.g., a child holding up a hand for “wait”) alongside the word in both English and Tamil script.

Peer Interaction Supports

Durgesh initially avoided peer play, spending 87% of free-choice time near adults or engaged in solitary parallel activity. A peer-mediated intervention was launched using the *Friendship Circle* model developed by the University of Illinois at Chicago. Three neurotypical peers (ages 29–31 months) were trained over four 15-minute sessions to initiate simple, predictable interactions:

  1. Offer a preferred toy (e.g., Fisher-Price® Laugh & Learn Smart Stages™ Scooter)
  2. Use a scripted phrase (“Want to push?”)
  3. Wait 5 seconds for response before modeling a gesture or word
  4. Provide immediate reinforcement (smile + verbal praise) regardless of response type

Duration of peer proximity increased from 1.2 to 8.7 minutes per 30-minute block; joint attention episodes rose from 0.8 to 5.4 per session. Notably, Durgesh initiated 12 unprompted peer bids in Week 12—compared to zero at baseline—with 75% involving shared object manipulation (e.g., passing blocks).

Behavioral Regulation and Emotional Literacy

Tantrums occurred most frequently during transitions (68% of incidents) and lasted an average of 4.7 minutes (SD = 1.9), often including kicking, screaming, and head-banging against padded mats. Functional behavior assessment (FBA) identified escape from non-preferred tasks and access to adult attention as primary maintaining consequences. Antecedent strategies were prioritized over consequence-based responses.

The CSEFEL 5-Step Calm-Down Toolkit was implemented consistently across all staff and caregivers. Steps include: (1) Name the feeling (“You’re feeling frustrated”), (2) Validate (“It’s okay to feel that way”), (3) Offer choice (“Would you like the blue timer or the green timer?”), (4) Teach strategy (“Let’s take three big breaths together”), and (5) Re-engage (“Now let’s finish building the tower”). Timers used were Time Timer® SE (3-inch model) set to 90 seconds—validated in pilot studies with toddlers as young as 24 months for improving temporal awareness.

Progress was tracked using a digital tally system (Google Sheets) synced across devices. Staff recorded start/end time, antecedent, observable behavior, and adult response. Data revealed that when Step 3 (offering choice) was omitted, tantrum duration increased by 41% (p < 0.01, t-test). When breathing instruction used concrete motor cues (“Smell the flower, blow out the candle”), success rate rose to 89% versus 52% with abstract language (“Take deep breaths”).

Data Tracking and Progress Monitoring

Progress was evaluated using multiple concurrent measures collected three times weekly:

Graphs were generated automatically using Chart.js and reviewed biweekly in team huddles. A key finding was the lag between sensory regulation gains and language growth: sensory tool usage plateaued at Week 6, while expressive language acceleration began at Week 8—suggesting neurological readiness for symbolic communication followed physiological stabilization.

Environmental and Curriculum Adaptations

The classroom curriculum was adjusted using Universal Design for Learning (UDL) principles. Lesson plans were revised to embed multiple means of engagement, representation, and expression. For example, during a unit on weather, Durgesh received:

Classroom layout changes included lowering shelf height to 24 inches (per NAEYC Space Guidelines), adding floor tape markers for “quiet feet” pathways, and installing acoustic panels (Acoustimac® 2” thick foam) in the literacy nook to reduce ambient noise levels from 58 dB to 42 dB (measured with Extech SL100).

Caregiver Partnership and Cultural Responsiveness

Family involvement was structured around cultural values articulated during intake: collectivism, respect for elders, and emphasis on oral tradition. Instead of traditional parent-teacher conferences, monthly “Story Circle Nights” were held—families shared folktales in Tamil or English while educators modeled responsive listening and connection-building techniques. Durgesh’s grandmother contributed a hand-sewn cloth book featuring Tamil animal names and corresponding English translations, now used daily in morning circle.

Home–school communication utilized a dual-language notebook (Mead® Primary Journal, 70-page, spiral-bound) with color-coded sections: green for educator notes, orange for family observations, and purple for shared goals. Entries were limited to ≤3 sentences each, with space for quick sketches. Average daily completion rate was 94% over 12 weeks—significantly higher than standard paper-based logs (historical average: 61%).

Sustained Outcomes and Next Steps

By Week 12, Durgesh met or exceeded all three IEP goals:

  1. Spontaneous use of gestures/words during meals increased from 1.2 to 5.6 per meal (observed across 30 meals)
  2. Floor-sitting meltdowns decreased from 4.3 to 0.4 incidents per day (p < 0.001, Wilcoxon signed-rank test)
  3. Toileting independence achieved: 82% dry diaper checks over 5 consecutive days, per Texas ECI toileting readiness protocol

Post-intervention follow-up at 6 months showed maintenance of gains: expressive vocabulary stabilized at 86 words (CDI 49th percentile), DECA-I Self-Regulation T-score improved to 52, and teacher-rated social competence (using the Social Skills Improvement System–Rating Scales) placed him at the 76th percentile. He transitioned successfully to a mainstream pre-K program with a 1:3 paraprofessional ratio for the first month only—reduced to consultation-only support by Month 2.

Future priorities include expanding narrative language (target: 3-step sequenced stories), supporting early literacy through phonemic awareness games (e.g., Hape® Wooden Phonics Puzzle), and fostering autonomy in self-care routines. Durgesh’s case exemplifies how precise, culturally attuned, and measurement-driven interventions can catalyze rapid developmental shifts—even in toddlers presenting with multiple risk factors. It underscores that consistency, fidelity, and caregiver agency—not intensity or duration—are the strongest predictors of sustainable outcomes.

What distinguishes Durgesh’s progress is not exceptional talent or accelerated pace—but the rigorous application of developmentally appropriate, relationship-based practices grounded in empirical validation. His educators did not rely on generic strategies or commercial curricula alone. They leveraged precise measurement, cross-disciplinary collaboration, and unwavering commitment to family voice. Every adjustment—from the decibel level of classroom acoustics to the weight of a lap pad—was informed by objective data and developmental science. This level of fidelity transforms theoretical frameworks into tangible, life-altering outcomes for toddlers and their families.

For practitioners, Durgesh’s case reinforces several non-negotiables: First, baseline data must be collected using standardized, norm-referenced instruments—not anecdotal impressions. Second, environmental modifications should precede behavioral interventions whenever sensory or physical barriers are identified. Third, caregiver capacity—not compliance—is the metric for partnership success. When Durgesh’s mother reported she could now anticipate his distress cues 12 seconds before escalation (versus 2 seconds at baseline), that represented not just skill acquisition—but restored parental confidence.

From a policy perspective, Durgesh’s outcomes align closely with Head Start’s Performance Standards for Individualization (45 CFR §1304.21(c)) and the Texas Education Agency’s Early Childhood Outcomes (ECO) indicators. His growth in self-regulation directly maps to ECO Indicator 2 (positive social relationships), while language gains reflect Indicator 1 (positive approaches to learning). Documentation met all federal audit requirements for Part C services, including timestamped video evidence, signed parent consent forms, and quarterly progress reports formatted per IDEA 2004 guidelines.

No single strategy ‘fixed’ Durgesh. Rather, it was the cumulative effect of coordinated, precise, and compassionate actions—each rooted in developmental neuroscience and delivered with relational consistency. His story affirms what decades of early childhood research confirm: when we meet toddlers where they are—neurologically, linguistically, culturally—we unlock potential not through correction, but through calibrated support.

His current favorite phrase—“My turn, please”—spoken clearly while handing a puzzle piece to a peer—encapsulates the synthesis of all these efforts: autonomy, reciprocity, and belonging. It is not a milestone checked off a list. It is a declaration of personhood, spoken in two languages, witnessed by those who chose to listen deeply, measure honestly, and respond faithfully.

Early childhood professionals working with toddlers like Durgesh benefit from ongoing access to clinical supervision, interprofessional consultation, and protected planning time. In Durgesh’s setting, educators received 45 minutes weekly of collaborative problem-solving time with the BCBA and OT—protected from other duties and scheduled during paid work hours. This investment yielded a 37% reduction in staff-reported burnout (measured via Maslach Burnout Inventory–Educator Survey) and correlated strongly with intervention fidelity scores.

Finally, Durgesh’s journey highlights a critical truth often overlooked in early intervention discourse: developmental progress is rarely linear, but it is always relational. Every word he speaks, every breath he takes during a transition, every time he chooses the green timer over the blue one—it is evidence not of isolated skill mastery, but of trusted connection made visible. That connection remains the most powerful, evidence-based, and universally accessible intervention available to us.

For families reading this, know that consistency does not require perfection—it requires presence. For educators, remember that fidelity is measured not in rigid adherence to scripts, but in responsive attunement to the child’s shifting needs. And for systems-level leaders, understand that investing in educator well-being, clinical supervision, and family partnership infrastructure yields returns far exceeding any short-term budgetary calculus.

Durgesh continues to thrive—not because he overcame challenges, but because his world adapted to hold him with precision, patience, and profound respect for who he is, right now.
