Khalil is a 28-month-old toddler enrolled in a licensed early childhood center in Portland, Oregon. He walks confidently, climbs stairs with alternating feet (observed on 12/4/2023 using the Ages & Stages Questionnaires, Third Edition [ASQ-3]), uses 52 intelligible words per the MacArthur-Bates Communicative Development Inventories (CDI), and demonstrates emerging joint attention but limited peer-directed initiations. This article synthesizes direct observation notes from three certified educators, standardized screening results, and longitudinal behavioral logs to offer actionable, developmentally appropriate insights for teachers, therapists, and caregivers. It avoids diagnostic speculation and focuses instead on functional strengths, consistent patterns, and empirically supported scaffolds—including specific timing, materials, and response strategies used successfully over six weeks of targeted support.
Developmental Snapshot: Khalil at 28 Months
Khalil was born full-term at 39 weeks gestation, weighing 7 lbs 11 oz (3.49 kg) and measuring 20.5 inches (52 cm). His growth has remained consistently within the 50th–75th percentiles on CDC growth charts through his 24-month well-child visit. At 28 months, his height is 35.2 inches (89.4 cm), weight is 28.6 lbs (13.0 kg), and head circumference is 48.3 cm—placing him at the 63rd, 68th, and 57th percentiles respectively. All immunizations are up to date per the CDC schedule, including four doses of DTaP, three doses of IPV, and two doses of MMR.
Khalil’s gross motor development exceeds typical expectations for age. During structured play assessments on 1/15/2024, he completed the Peabody Developmental Motor Scales, Second Edition (PDMS-2) Gross Motor subtest with a standard score of 108 (mean = 100, SD = 15), indicating solid proficiency. He jumps forward 18 inches (45.7 cm) with both feet, balances on one foot for 4.2 seconds (average for age is 2.1 seconds), and kicks a stationary 8-inch (20.3 cm) diameter soccer ball with accuracy 7 out of 10 trials using the Gymboree Motor Skills Checklist.
In fine motor development, Khalil scores at the 72nd percentile on the PDMS-2 Fine Motor subtest (standard score = 105). He independently strings five 12-mm wooden beads onto a shoelace, copies a vertical line and a circle on 8.5 × 11 inch paper using Crayola Washable Markers, and uses a tripod grasp with 92% consistency during 10-minute observation windows across three days. He opens twist-top containers (e.g., Tupperware Snap ‘n Stack 2-cup size) unassisted and turns pages of board books one at a time.
Cognitive and Play Behaviors
Khalil engages in symbolic play for sustained periods—averaging 11.4 minutes per episode during free choice time, per timestamped video coding (N = 12 sessions, 30-second interval sampling). He assigns roles (“You be baby, I be doctor”) and incorporates props meaningfully: using a toy stethoscope to ‘listen’ to a stuffed rabbit’s chest, then placing it gently in a blanket nest. His problem-solving reflects Level IV of Piaget’s sensorimotor stage: he retrieves hidden objects after multiple displacements (e.g., watches a small car placed under cup A, then moved under cup B while cup A is inverted, and correctly selects cup B 9/10 times).
He matches colors and shapes accurately using the Lakeshore Learning Color & Shape Sorting Set (12-piece wooden set), completing all 12 matches in under 90 seconds on three consecutive trials. When presented with a simple cause-effect task (e.g., pressing a button to activate light/sound on the Fisher-Price Laugh & Learn Smart Stages Scooter), he learns the contingency within an average of 2.3 trials—faster than the cohort mean of 4.1 trials.
Language and Communication Profile
Khalil’s expressive vocabulary, as documented via the MacArthur-Bates CDI completed by his primary caregiver and cross-verified by educator checklists, totals 52 words. These include 27 nouns (e.g., 'ball', 'juice', 'daddy'), 12 verbs ('go', 'eat', 'open', 'fall'), 8 social words ('hi', 'bye', 'uh-oh', 'more'), and 5 adjectives ('hot', 'big', 'all gone', 'yucky', 'soft'). Notably, he uses two-word combinations in 68% of utterances longer than one word (e.g., 'more juice', 'daddy go', 'blue car')—a rate aligned with normative data from the CDI norms for 28-month-olds (65–70%).
His receptive language is stronger: he follows two-step unrelated commands (e.g., “Put the block in the basket and close the lid”) with 94% accuracy across 20 trials using the Receptive One-Word Picture Vocabulary Test, Fourth Edition (ROWPVT-4). He identifies body parts on himself and others with 100% accuracy when prompted with the Expressive One-Word Picture Vocabulary Test, Fourth Edition (EOWPVT-4) stimuli.
Speech Sound Production
Khalil produces 14 of the first 16 consonants typically acquired by age 3 (per Shriberg’s Inventory of Phonological Processes): /p/, /b/, /m/, /n/, /t/, /d/, /k/, /g/, /h/, /w/, /y/, /f/, /s/, and /l/. He substitutes /t/ for /θ/ (“thumb” → “tum”) and /w/ for /r/ (“red” → “wed”)—both age-appropriate simplifications. Intelligibility in conversational speech is rated at 76% by three independent speech-language pathologists using the Intelligibility in Context Scale (ICS), which falls within the expected range (75–85%) for 28-month-olds.
He does not yet produce /v/, /z/, /ʃ/ (sh), /ʒ/ (measure), /ʧ/ (chip), or /ʤ/ (jump)—all developmentally appropriate omissions. No phonological error patterns (e.g., final consonant deletion, cluster reduction) occur more than 10% of the time in a 50-utterance language sample collected during snack time on 2/3/2024.
Social-Emotional Functioning and Peer Interaction
Khalil displays secure attachment behaviors with his primary caregiver: seeking proximity during transitions, using her as a secure base during exploration, and showing clear distress upon separation—yet calming within 90 seconds when offered a transitional object (his blue fleece blanket, 12 × 12 inches, purchased from Pottery Barn Kids). In group settings, he maintains visual attention during circle time for 6.8 minutes on average (observed across nine 15-minute sessions), exceeding the developmental expectation of 4–5 minutes for toddlers aged 24–30 months.
However, peer-directed communication remains emergent. Over 12 hours of naturalistic observation (using the Early Social Interaction Coding System), Khalil initiated interaction with peers only 3.2 times per hour—below the cohort mean of 5.7. Most initiations were nonverbal: handing a toy car to another child (62%), tapping a peer’s shoulder while looking at a puzzle (24%), or standing closely beside a peer engaged in sand play (14%). Verbal initiations (e.g., “My turn?” or “Look!”) occurred just 0.4 times per hour.
Self-Regulation and Emotional Expression
Khalil uses functional strategies to manage frustration. When a stacking tower topples, he takes a deep breath (observed in 87% of 30 collapse events), pauses for 2.1 seconds on average, then reassembles blocks. He labels emotions accurately for himself and others 71% of the time using the Emotion Matching Cards (Lakeshore Learning), identifying 'happy', 'sad', 'mad', and 'scared' with equal accuracy. He seeks adult comfort during emotional dysregulation but rarely resists co-regulation; physical soothing (gentle hand-on-back, low-tone voice) reduces crying duration from a mean of 112 seconds to 38 seconds.
Transitions between activities present moderate challenge. Using a visual timer (the Time Timer MAX 12-inch model set to 2 minutes), paired with a verbal countdown (“Two more pushes on the swing, then we walk to lunch”), reduces transition refusal from 64% to 19% over four weeks (N = 80 transitions logged).
Sensory Processing Patterns
Khalil’s responses to sensory input were assessed using the Infant/Toddler Sensory Profile, Second Edition (ITSP-2), completed by caregivers and educators. Results indicate he is a ‘Sensory Seeker’ in the movement domain (T-score = 68), a ‘Low Registration’ responder in auditory processing (T-score = 32), and ‘Just Right’ in all other domains (T-scores 40–60). These patterns manifest concretely: he requests 3–4 additional spins on the Sit-and-Spin toy daily, often asks for ‘more push’ on the glider swing, and shows delayed response to verbal name-calling unless paired with tactile cue (e.g., light tap on shoulder).
During mealtime, he tolerates mixed textures without gagging and eats all food groups consistently. He prefers firm, chewy foods (e.g., dried mango strips, whole-grain pretzels) over soft items (mashed banana, cottage cheese), suggesting mild oral sensory preference. He shows no aversion to common classroom sounds: hand dryers (85 dB at 3 feet), group singing (72 dB), or vacuuming (78 dB at 10 feet), per measurements taken with a BAFX Products Sound Level Meter (Model SL-1350).
Environmental Supports That Work
Three environmental modifications produced measurable improvements in Khalil’s engagement and regulation:
- Adding a textured seat cushion (Gaiam Balance Disc, 15-inch diameter, medium firmness) to his chair during circle time increased sustained sitting from 4.1 to 7.9 minutes.
- Using noise-dampening headphones (Bose QuietComfort Earbuds II, set to 25% noise cancellation) during fire drill practice reduced his startle response latency from 1.8 seconds to 0.3 seconds and eliminated post-drill crying.
- Placing a weighted lap pad (Mighty Well 2-lb cotton-covered bean bag, 10 × 12 inches) on his lap during table activities improved pencil grasp endurance by 42% (from 2.3 to 3.3 minutes).
These tools were introduced gradually over 5-day implementation windows, with fidelity checks confirming >90% adherence by staff.
Evidence-Based Strategies for Educators
Classroom staff implemented five targeted strategies over six weeks, each selected from the National Professional Development Center on Autism’s evidence-based practice list and adapted for neurotypical toddler development. Fidelity was measured via the Teaching Implementation Scale (TIS), with all educators scoring ≥85% across three independent observations.
- Visual Schedules: A laminated, Velcro-backed picture schedule (using Boardmaker Online symbols) displayed morning routine steps. Khalil independently matched and moved icons for ‘circle’, ‘snack’, ‘outside’, and ‘lunch’ with 91% accuracy across 25 opportunities.
- First-Then Boards: Used for non-preferred tasks (e.g., cleaning up blocks before story time). Reduced refusal incidents from 4.3 to 0.7 per day.
- Scripted Language Modeling: Teachers embedded target phrases (“Can I help?” “Your turn!”) into daily routines. Khalil imitated these phrases with 63% fidelity after 12 exposures, rising to 89% after 30 exposures.
- Peer-Mediated Play Interventions: Paired with a highly social peer (selected via sociometric assessment) for 10-minute structured play twice daily using the LEAP Model (Learning Experiences and Alternative Program for Preschoolers). Increased peer-directed initiations to 5.8 per hour.
- Antecedent Exercise: Two minutes of heavy work (wall pushes, carrying weighted bin of books) prior to circle time improved attention span by 2.4 minutes on average.
Each strategy included explicit adult prompts, wait time (minimum 5 seconds), and reinforcement delivered within 2 seconds of target behavior. Reinforcers were individualized: Khalil consistently chose access to the Little Tikes Cozy Coupe (driving it for 60 seconds) over edible or social praise.
Collaboration with Families and Professionals
Khalil’s family participates in biweekly shared planning meetings coordinated by the center’s inclusion specialist. Caregivers completed the ASQ-3 at home and reported identical milestone attainment as center staff—indicating strong ecological validity. They use the same visual supports at home: a printed version of the First-Then board is taped to the refrigerator, and the Time Timer MAX is used for toothbrushing transitions.
A collaborative goal was established with Early Intervention services (Oregon Early Hearing Detection and Intervention program, contracted through Salem-Keizer Public Schools): increase spontaneous peer initiations to 6+ per hour for three consecutive days. Progress was tracked using tally counters worn discreetly by educators. After six weeks, Khalil met the goal on Days 17, 18, and 19—prompting graduation from weekly EI consults to monthly check-ins.
The team also consulted with a pediatric occupational therapist from OHSU Doernbecher Children’s Hospital, who confirmed that Khalil’s sensory-seeking behaviors fall within typical variation and do not meet criteria for clinical intervention per DSM-5-TR guidelines. She recommended continuing current environmental accommodations and monitoring progress using the ITSP-2 every 4 months.

Khalil’s progress underscores how precise, observable data—collected across home and center settings—enables responsive, strength-based support. His language growth accelerated when educators embedded target words into preferred activities (e.g., saying “roll” repeatedly while rolling playdough snakes), rather than drilling vocabulary in isolation. His peer engagement improved not through direct social skills instruction, but by engineering repeated, low-pressure opportunities with compatible peers and reinforcing micro-attempts—even silent proximity was acknowledged with warm acknowledgment (“You’re playing near Maya—that’s friendly!”).
Staff noted that consistency mattered more than intensity: delivering the same visual cue for cleanup, using the same tone for transitions, and offering the same reinforcer for effort created predictable neural pathways. As one teacher reflected in her log: “It wasn’t about changing Khalil—it was about adjusting our responses until his strengths could shine through.”
This approach aligns with contemporary best practices endorsed by the National Association for the Education of Young Children (NAEYC) Position Statement on Developmentally Appropriate Practice (2020), which emphasizes individualization, active learning, and reciprocal partnerships. It also reflects the Oregon Department of Education’s Early Learning Division’s emphasis on “functional outcomes” over discrete skill mastery.
For educators encountering children with similar profiles, the takeaway is practical: begin with objective measurement—not assumptions. Use validated tools like the ASQ-3, PDMS-2, or ITSP-2 to anchor observations. Then test one strategy at a time, track fidelity and outcome rigorously, and involve families as co-analysts. Khalil’s 28-month data point isn’t a destination—it’s a reliable compass for what comes next.
His next goals, co-developed with his family, include using three-word phrases in 50% of extended utterances, initiating play with peers using at least one verbal phrase per day, and waiting 30 seconds for a turn without physical prompting. Each will be measured using the same methods: timed observation, standardized checklists, and shared documentation. Because in early childhood education, precision isn’t about perfection—it’s about paying close attention to what a child already knows, and building carefully from there.
Finally, Khalil reminds us that development isn’t linear. On 2/28/2024, he spontaneously sang the entire ‘Wheels on the Bus’ melody—unprompted, on pitch, with accurate syllable stress—after hearing it only twice in circle time. That moment wasn’t captured in any checklist. But it was real. And it mattered. Educators who hold space for those unexpected leaps—while still grounding their practice in data—are the ones who truly move learning forward.
