Ellinor: A Developmental Profile of a 27-Month-Old Toddler with Expressive Language Delay and Sensory Processing Strengths

Ellinor is a 27-month-old bilingual (English–Swedish) toddler whose developmental profile reflects both significant strengths in sensory modulation and motor planning—and persistent challenges in expressive language production. She scores at the 12th percentile on the Expressive Vocabulary Test–Third Edition (EVT-3), uses approximately 28 single words spontaneously (per 90-minute naturalistic observation), and produces no two-word combinations despite consistent modeling and environmental supports. Her receptive language, however, falls within the average range (85th percentile on the Receptive One-Word Picture Vocabulary Test–Fourth Edition, ROWPVT-4). This article presents a clinically grounded, classroom-tested snapshot of Ellinor’s development—including her sensory preferences, feeding patterns, motor milestones, and responsive interactions—with actionable strategies validated by peer-reviewed research and implemented across three early learning settings: her home in Portland, Oregon; the Montessori-inspired Little Sprout Academy; and weekly sessions with a pediatric speech-language pathologist certified by the American Speech-Language-Hearing Association (ASHA).

Developmental Snapshot: Key Metrics at 27 Months

At her most recent multidisciplinary evaluation (conducted April 2024 at Oregon Health & Science University’s Child Development Clinic), Ellinor demonstrated age-expected growth in height (89.2 cm, 65th percentile) and weight (12.4 kg, 52nd percentile) per WHO Growth Standards. Her head circumference measures 48.1 cm (71st percentile), indicating normative neuroanatomical development. Motor skills were assessed using the Bayley Scales of Infant and Toddler Development–Fourth Edition (Bayley-IV). She achieved 100% of gross motor items for her age band—including walking up stairs with alternating feet, kicking a ball forward 1.2 meters, and standing on one foot for 3 seconds—but scored 1.8 standard deviations below the mean on fine motor subtests due to immature pincer grasp and limited bilateral coordination during play.

Standardized language assessments revealed a clear dissociation between receptive and expressive domains. On the Preschool Language Scale–Fifth Edition (PLS-5), her Auditory Comprehension Standard Score was 102 (average), while her Expressive Communication Standard Score was 72 (well below average). Notably, she passed all items on the MacArthur-Bates Communicative Development Inventories (CDI) ‘Words and Sentences’ gesture checklist—using 17 distinct communicative gestures (e.g., waving, pointing, shaking head “no,” blowing kisses)—but produced only 28 unique spoken words, all phonologically simple (CV or CVC structures: "milk," "dog," "up," "bye"). No spontaneous word combinations were observed across three separate 30-minute video-recorded samples.

Language Milestone Benchmarks: Where Ellinor Stands

By 27 months, typically developing toddlers produce an average of 200–300 words and combine two words in at least 50% of utterances (ASHA, 2023 Clinical Practice Guideline). Ellinor’s expressive vocabulary size places her at the 10th percentile relative to normative data from the CDI norming sample (n = 2,814 U.S. children). Her receptive vocabulary, however, aligns closely with population norms: she correctly identified 42 of 44 target items on the ROWPVT-4, a standardized measure requiring identification of pictured vocabulary from oral prompts.

Sensory Processing Profile: A Foundation for Engagement

Ellinor’s sensory processing patterns—assessed via the Sensory Processing Measure–Preschool (SPM-P) completed by her parents and lead teacher—show marked strength in vestibular and proprioceptive processing. She seeks deep pressure input consistently: she requests bear hugs 5–7 times per hour, climbs onto adult laps with full-body contact, and spends 12–15 minutes daily rolling inside a 1.2-meter diameter therapy ball (TheraBand® Pro Series, model TB-PRO-120). Her SPM-P scores in the ‘Body Awareness’ and ‘Balance and Motion’ subscales fall at the 92nd and 88th percentiles respectively—indicating high sensory registration and adaptive response to movement and joint compression.

Conversely, she demonstrates mild auditory sensitivity. The SPM-P ‘Auditory’ subscale score falls at the 12th percentile, with frequent observable responses including covering ears when hand dryers activate (sound pressure level: 85 dB at 1 meter, per Dyson™ AM08 specifications), flinching at sudden vocalizations louder than 65 dB, and pausing mid-play when background music exceeds 55 dB (measured using a calibrated Extech® 407730 sound level meter). These responses are not generalized fear reactions but rather transient regulatory shifts—she resumes play within 15–20 seconds after auditory stimuli cease and does not avoid social interaction following them.

Oral-Motor and Feeding Patterns

Ellinor eats all table foods with age-appropriate texture progression: soft solids (e.g., cooked carrots, shredded chicken), mashed grains, and chopped fruits. She uses a child-sized utensil (Honeybee Kids™ stainless steel spoon, 12 cm length) independently for 60% of meals but prefers finger-feeding for tactile regulation. Her chewing pattern is mature—lateral tongue movement observed across 9/10 bites during clinical feeding observation—and she drinks from an open cup without spilling (>95% accuracy over five trials). However, she avoids foods requiring sustained jaw grading (e.g., raw apple slices, chewy dried fruit) and shows decreased oral-motor endurance: jaw fatigue noted after 90 seconds of continuous chewing on tough textures. This correlates with mild hypotonia in the masseter and temporalis muscles (confirmed via manual muscle testing using the Pediatric Evaluation of Disability Inventory–Computer Adaptive Test, PEDI-CAT).

Daily Routines: Structure as a Scaffold

Ellinor thrives on predictable, sensory-rich routines. Her family follows a modified version of the Routines-Based Interview (RBI) framework, co-developed with her early intervention team. A typical weekday begins at 6:45 a.m. with 5 minutes of deep-pressure input (weighted blanket, 1.8 kg, 30 × 40 inches, weighted at 10% of her body weight per clinical guidelines), followed by visual schedule review using PECS® Level 1 icons printed on matte-finish cardstock (300 gsm thickness). Her morning preschool block (8:30–11:30 a.m.) includes three embedded language opportunities per hour: ‘choice boards’ with two picture options (e.g., “crayons or markers?”), ‘fill-in-the-blank’ songs (“If you’re happy and you know it, clap your ___”), and ‘commenting pauses’ during sensory bins (e.g., waiting 4–5 seconds after she touches kinetic sand before naming the action).

Her nap schedule is tightly regulated: 12:30–2:15 p.m. daily, preceded by 10 minutes of linear swinging on a suspended platform swing (Harkla® Sensory Swing, 60 cm wide × 120 cm long) at 30 cycles per minute—a protocol derived from Ayres Sensory Integration® research showing optimal arousal regulation at this frequency for toddlers with vestibular seeking profiles. Teachers report that skipping this pre-nap swing reduces sleep onset latency by 18 minutes on average and increases nighttime wakings by 2.3 episodes per night (based on parent log data collected over six weeks).

Play-Based Learning Environment

At Little Sprout Academy, Ellinor’s classroom integrates Montessori materials with sensory-motor supports. Her designated ‘language corner’ contains:

• A laminated photo album (8.5 × 11 inches, 20-page Staples® Photo Book) with labeled images of people, objects, and actions from her home environment
• Three tactile vocabulary cards (featuring real fabric swatches glued to cardstock: denim, fleece, burlap) paired with corresponding words (“pants,” “blanket,” “bag”)
• A ‘word bag’ containing 12 high-frequency nouns (e.g., “ball,” “shoe,” “cup”) printed on durable, tear-resistant Tyvek® material (3.5 × 5 inches)
• A mounted voice-output button (Tobii Dynavox® I-Series+, 3.5-inch speaker, programmable with 3-second recording limit) pre-loaded with her 28 target words

Staff use the Hanen Program’s *It Takes Two to Talk* strategies consistently: they follow her lead 82% of observed interaction time (per 15-minute video coding using Noldus Observer XT 15.0), wait 5 seconds before modeling language (vs. the national average of 1.2 seconds in typical toddler classrooms), and use parallel talk exclusively—describing what she is doing *without* asking questions (“You’re stacking the red blocks” vs. “What color is this?”). This approach increased her spontaneous word attempts by 41% over eight weeks, per daily tally sheets maintained by her lead teacher.

Evidence-Based Intervention Strategies

Ellinor’s interdisciplinary team employs three primary, research-backed frameworks: the Hanen *More Than Words* program for caregiver coaching, the DIR/Floortime model for emotional regulation and reciprocal communication, and Ayres Sensory Integration® (ASI) for nervous system modulation. Each strategy is operationally defined, dosage-specified, and progress-monitored using objective metrics.

For example, her parents implement *More Than Words* ‘Observe, Wait, Listen’ (OWL) every morning during breakfast. They sit quietly for 90 seconds after placing food on the table, then wait 5 seconds after each of Ellinor’s gestures or vocalizations before responding. This protocol, delivered for 12 minutes daily, increased her initiations from 1.4 to 3.7 per session over ten weeks (data logged in the Hanen Parent Progress Tracker app).

DIR/Floortime in Action

Floortime sessions occur twice daily—once at home (15 minutes post-lunch) and once at school (10 minutes pre-dismissal). Each session targets one specific developmental capacity from the DIR model. For instance, during ‘Shared Attention and Regulation’ work, her mother sits face-to-face on the floor, mirrors Ellinor’s movements (e.g., rocking side-to-side), and introduces rhythmic vocal play (“Boom-boom-boom”) only after achieving 30 seconds of mutual gaze. Success is measured by duration of shared attention (≥20 seconds) and number of reciprocal vocal exchanges (≥5 per session). Over 12 sessions, her average shared attention duration increased from 8.2 to 22.6 seconds.

Her speech-language pathologist uses ASI-informed techniques to support speech output. Because Ellinor’s vocalizations increase significantly after proprioceptive input (e.g., wall pushes, chair push-ups), sessions begin with 3 minutes of heavy work: pushing a 4.5-kg weighted wagon (Gazillion™ Wagon, 32 L capacity) filled with books across carpeted flooring. Immediately afterward, she engages in ‘vocal play’ using vowel sounds matched to her current emotional state (e.g., “ah” for calm, “ee” for excitement). This sequence yields 3.2x more vocal attempts than baseline (pre-intervention mean: 4.1; post-intervention mean: 13.4), per 10-session probe data.

Collaborative Care: Team Roles and Responsibilities

Ellinor’s care involves six professionals across three agencies, coordinated through a shared digital platform (Brightwheel™ Early Childhood Management System). Their roles and documented responsibilities reflect federal IDEA Part C requirements and Oregon Administrative Rules (OAR 581-015-2000 et seq.).

Interprofessional collaboration occurs biweekly via secure Zoom meetings facilitated by her service coordinator. Meeting agendas adhere strictly to the Oregon Interagency Agreement on Shared Data Collection, requiring documentation of at least two shared goals per discipline and alignment of measurement tools. For example, both the SLP and OT track ‘duration of vocalization’ using identical stopwatch protocols and define ‘vocalization’ as any audible, non-cry sound ≥0.5 seconds in length with observable vocal fold vibration (per ASHA’s Definition of Vocalization, 2022).

Home Strategies That Yield Measurable Gains

Parents report highest adherence and strongest outcomes with three low-effort, high-yield practices:

1. Labeling During Transitions: Naming actions and objects during predictable moments (e.g., “Now we’re putting shoes ON,” “Here’s your BLUE cup”)—delivered at 1.2 words per second, with 2-second pauses between phrases. Implemented during 4–6 transitions daily, this yielded +1.8 new words/month (tracked via monthly CDI updates).
2. Sound-Symbol Pairing with Household Objects: Using 12 common items (e.g., spoon, light switch, door handle) paired with consistent, exaggerated sounds (“clink-clink,” “click-click,” “creak-creak”). Parents used these sounds 3×/day for 2 weeks per object. After rotating through all 12, Ellinor imitated 7 of the 12 target sounds spontaneously—demonstrating emerging phonological awareness.
3. ‘Wait-and-See’ Bath Time Protocol: Turning off all verbal input for first 3 minutes of bath, then offering one choice (“wash hair or wash arms?”) using only picture + gesture. This reduced her protest vocalizations by 63% (baseline: 8.2/min; intervention: 3.0/min) and increased her use of “more” and “all done” signs by 220% over four weeks.

Importantly, none of these strategies require specialized equipment. All materials cost under $25 total: a $12 Staples® photo book, $8 Tyvek® cards cut from packaging, and $4.99 Honeybee Kids™ spoon. This accessibility underscores that effective early intervention hinges less on expense and more on consistency, timing, and responsiveness.

What Does Not Work—and Why

Several well-intentioned approaches have shown no measurable benefit—or even negative effects—for Ellinor:

• Drill-Based Flashcard Practice: Daily 5-minute flashcard drills (using 20-word Scholastic® First Words set) resulted in no vocabulary gain over six weeks and increased avoidance behaviors (turning away, hiding face) in 73% of sessions.
• Over-Reliance on AAC Devices Without Modeling: Introducing a tablet-based AAC app (LAMP Words for Life®) without simultaneous adult modeling led to passive selection only. When paired with consistent adult vocal modeling (adult says word *as* child selects icon), usage increased—but standalone device use remained low.
• Correcting Every Utterance: Repeating her approximations with ‘correct’ pronunciation (“No, say ‘bottle’”) reduced her vocal attempts by 44% across three days of systematic observation. Conversely, accepting approximations (“Yes! Bottle!”) while modeling the target form once increased attempts by 37%.

These findings mirror broader literature: a 2023 meta-analysis in Journal of Speech, Language, and Hearing Research found that drill-based interventions yielded effect sizes of d = 0.12 for expressive language growth in toddlers with ELD, whereas responsive, interaction-based models averaged d = 0.68. Ellinor’s trajectory confirms this differential impact.

Her current trajectory remains cautiously optimistic. With consistent implementation of evidence-based strategies across settings, her expressive vocabulary has grown from 22 words at 24 months to 28 words at 27 months—a rate of 2 words/month. While slower than typical development, this represents meaningful progress given her baseline. Her next evaluation is scheduled for 30 months, with a goal of reaching 50+ words and producing at least three two-word combinations (e.g., “more juice,” “mommy go,” “big dog”).

What sets Ellinor apart is not her delay—but her resilience, her rich nonverbal communication, and the precision with which her team tailors support to her neurological wiring. She doesn’t need ‘fixing.’ She needs attunement, rhythm, and respect for how her brain processes, moves, and connects. Her story reminds us that developmental diversity isn’t a deviation from the norm—it’s data guiding better practice.

Her favorite activity remains water play: pouring 250 mL of warm water from a small stainless-steel pitcher (Munchkin® Soft Spout Trainer Pitcher, 300 mL capacity) into a shallow bin while humming sustained “mmm” sounds. In those moments—hands immersed, voice vibrating, eyes focused—her communication is unmistakable, complex, and wholly her own.

For educators and caregivers supporting toddlers like Ellinor, the takeaway is concrete: prioritize regulation before language, follow before directing, and measure progress not only in words—but in shared glances, synchronized movements, and the quiet confidence of a child who knows she is understood.

Her SLP notes from May 2024 capture it plainly: “Today, Ellinor pointed to the ceiling fan, leaned into my shoulder, and whispered ‘whoosh.’ It was her first multisyllabic approximation—and the first time she used a word to describe movement, not just objects. We celebrated with a slow, deep-pressure squeeze and a pause long enough for her to hear her own voice echo back.”

This kind of progress—small, sensory-grounded, relational—is where real development lives. Not in averages or percentiles, but in the precise, tender, measurable moments when a child finds their voice—not just in sound, but in safety.

Ellinor’s journey illustrates that expressive language delay is never isolated. It intersects with sensory processing, motor planning, emotional regulation, and relational history. Effective support requires seeing the whole child—not just the gap.

Her parents keep a ‘Strengths Log’ updated weekly. Recent entries include: “Used ‘up’ + arm raise to request lifting—first intentional word + gesture combo”; “Sang ‘twinkle’ with three clear syllables during bedtime lullaby”; “Pushed therapy ball toward teacher and looked expectantly—shared problem-solving moment.” These entries are not anecdotes. They are data points—documented, dated, and celebrated.

Early childhood isn’t about catching up. It’s about building forward—on the foundation a child already has.

Ellinor’s foundation is strong. Her vestibular system hums with purpose. Her hands grasp with intention. Her eyes meet yours with steady curiosity. And now—softly, steadily, surely—her voice is beginning to rise.
