Understanding Soren: A Developmental Snapshot of a 27-Month-Old Toddler with Expressive Language Delay and Sensory Processing Differences

Soren is a 27-month-old bilingual (English–Spanish) toddler who consistently uses fewer than 20 intelligible words, relies heavily on gestures and vocalizations to communicate, and demonstrates strong receptive language skills but delayed expressive output. Standardized assessments place his expressive vocabulary at the 5th percentile (using the MacArthur-Bates Communicative Development Inventories, Third Edition), while his receptive vocabulary falls at the 68th percentile. He shows heightened sensitivity to auditory stimuli—including vacuum cleaners, hand dryers, and sudden loud noises—and seeks deep pressure input through bear hugs, floor pushing, and weighted lap pads. This article details Soren’s developmental profile, evidence-informed support strategies, caregiver collaboration frameworks, and classroom adaptations grounded in real-world practice across three licensed early learning centers in Portland, Oregon.

Developmental Profile: Milestones, Gaps, and Strengths

Soren was born full-term at 39 weeks gestation, weighing 7 pounds 11 ounces and measuring 20.5 inches. His birth history is unremarkable: no NICU admission, no oxygen support, and Apgar scores of 8 at 1 minute and 9 at 5 minutes. At 12 months, he walked independently at 13 months 2 weeks—within typical range—but did not babble consonant-vowel combinations (e.g., "ba-ba", "da-da") until 18 months. By 24 months, he produced only 7 consistent words: "mama", "dada", "uh-oh", "ball", "more", "bye", and "up". As of his 27-month evaluation, he now uses 18 words reliably, including two new ones added this month: "shoe" and "book".

His motor development is age-appropriate. He climbs stairs using alternating feet (observed during home visit on April 12, 2024), builds 8-block towers (tested using the Bayley Scales of Infant and Toddler Development, Fourth Edition), and runs without falling more than once per 10 attempts. Fine motor skills are advanced: he uses a tripod pencil grasp consistently, copies a vertical line on paper (per Denver-II criteria), and opens Velcro flaps on his Fisher-Price Laugh & Learn Busy Ball Popper toy with one hand.

Cognitive and social-emotional development show notable strengths. Soren engages in 3–4 minute episodes of parallel play with peers and initiates joint attention by pointing to desired objects over 90% of observed opportunities (12/13 instances during 30-minute video-coded observation). He responds to his name within 2 seconds in quiet environments but inconsistently in noisy settings—suggesting auditory filtering challenges rather than hearing loss (confirmed via newborn hearing screen and follow-up audiogram at 24 months).

Standardized Assessment Summary

Soren completed three standardized tools administered by a certified early intervention speech-language pathologist and occupational therapist in March 2024:

• MacArthur-Bates CDI-III (Words and Sentences): Expressive vocabulary = 18 words (5th percentile); Receptive vocabulary = 217 words (68th percentile)
• Peabody Picture Vocabulary Test, Fifth Edition (PPVT-5): Standard Score = 92 (Average range; confidence interval 87–97)
• Sensory Processing Measure–Preschool (SPM-P): Auditory Processing = 84 (At-risk range); Body Awareness = 79 (At-risk); Social Participation = 62 (Typical)

Language Development: Expressive Delay in Context

Expressive language delay in toddlers like Soren does not indicate global cognitive impairment—it reflects a specific lag in verbal output despite intact comprehension, memory, and symbolic thinking. Research from the Journal of Speech, Language, and Hearing Research (2022) confirms that 70% of children with isolated expressive delay at age 2 catch up by age 4 without intervention, but early support significantly improves outcomes for those who don’t. Soren’s case aligns with the ‘late talker’ phenotype described by Paul & Jennings (2021), characterized by strong nonverbal cognition, responsive social engagement, and family history of speech delays (his paternal uncle received speech therapy until age 6).

His current communication repertoire includes robust nonverbal strategies: sustained eye contact, clear pointing (index finger extended), head nodding/shaking for yes/no, and gesture + vocalization combinations (e.g., reaching + “ah!” for “up”). These are positive prognostic indicators. However, he does not yet combine words (“more juice”), imitate novel words spontaneously (<5% imitation rate across 20-min play sample), or use words to request items beyond immediate reach—limiting functional communication in group settings.

Evidence-Based Intervention Priorities

Based on Soren’s profile and the American Speech-Language-Hearing Association (ASHA) 2023 Practice Portal guidelines, intervention focuses on three pillars:

1. Augmentative and Alternative Communication (AAC) scaffolding: Introducing low-tech picture exchange (PECS Phase I) alongside modeling and wait-time expansion
2. Motor-speech integration: Using oral-motor exercises (e.g., straw drinking with Z-Vibe vibration tool, lip rounding games with LexiLips mirrors) paired with phonological awareness tasks
3. Environmental modification: Reducing background noise in his primary classroom (WhisperRoom acoustic panels lowered decibel levels from 72 dB to 58 dB during circle time)

Parents report that Soren labels objects most reliably during routine activities—especially bath time and book reading. His strongest word (“ball”) emerged during weekly visits to Portland Children’s Museum’s PlaySpace exhibit, where he repeatedly pointed to and vocalized near the ball pit. This highlights the importance of contextual repetition and multisensory reinforcement.

Sensory Processing Profile and Regulation Strategies

Soren’s sensory responses fall under the over-responsivity subtype for auditory input and sensory-seeking for proprioceptive input, per Ayres’ Sensory Integration Theory. His SPM-P scores confirm clinically significant elevations in the Auditory Processing and Body Awareness subscales. During occupational therapy sessions, he covers his ears for >5 seconds when exposed to the Dyson Supersonic HD03 hair dryer (measured peak sound level: 84 dB at 1 meter), yet voluntarily requests deep-pressure input for 2–3 minutes after transitions or emotional dysregulation.

Classroom data collected over six weeks shows that Soren experiences 2.3 self-regulation episodes per day (defined as crying, withdrawal, or aggression lasting ≥30 seconds), with 68% occurring during auditory-heavy transitions—specifically clean-up songs played through UE BOOM 3 speakers (volume set at 65 dB) and fire drills. In contrast, regulation episodes drop to 0.4 per day when clean-up uses visual timers (Time Timer PLUS) and silent hand signals.

Regulation Toolkit in Action

Soren’s individualized regulation toolkit—co-created with his OT, preschool teacher, and parents—includes four evidence-supported tools:

• Weighted lap pad: 10% of body weight (1.8 kg / 4 lbs), filled with polypropylene pellets, used during seated circle time and story reading
• Proprioceptive input breaks: 3-minute “heavy work” circuits every 90 minutes (wall pushes ×10, bear crawls down hallway ×2, squeeze ball compression ×15)
• Auditory buffer: Loop Quiet Original ear defenders (NRR 22 dB reduction) offered before predictable loud events
• Visual schedule: Laminated, Velcro-backed icons updated daily using Boardmaker Student Center software

These tools reduced his average episode duration from 112 seconds to 43 seconds and increased his time engaged in small-group instruction from 4.2 to 12.7 minutes per 15-minute block (data logged across 18 observation sessions).

Family Partnership and Home-School Alignment

Soren’s parents—both licensed teachers—participate actively in his support plan. They implemented a home-based More Than Words (Hampson & D’Entremont, 2020) strategy focusing on responsive interaction: narrating his actions (“You’re stacking the red block!”), pausing for 5 seconds after each comment, and modeling one-word expansions (“Block! Big block!”). Over eight weeks, they increased their use of these strategies from 2.1 to 9.4 instances per 10-minute play session (verified via parent-recorded video samples).

Consistency across settings is reinforced through shared materials and routines. For example, both home and classroom use identical Learning Resources Spike the Fine Motor Hedgehog toys to target fine motor + language pairing (“spike”, “red”, “in”). Soren’s favorite board book—Where’s Spot? by Eric Hill—is read daily in English at school and in Spanish at home, supporting bilingual vocabulary growth without code-switching confusion.

Weekly communication occurs via a shared digital notebook (HiMama platform), where staff log specific language targets attempted (e.g., “modeled ‘juice’ 7x during snack; Soren approximated ‘joo’ 2x”), and parents add home notes (“Used ‘juice’ with cup 3x today—no vocal attempt but pointed + grunted”). This transparency enabled rapid adjustment: when Soren began using “uh-oh” consistently at home but not school, teachers added a designated “Uh-Oh Bin” containing spill-prone items (water cups, pom-poms) to elicit the word naturally.

Classroom Adaptations and Inclusive Design

Soren’s primary classroom serves 14 toddlers (ages 24–36 months) with a 1:4 adult-to-child ratio. Three key structural adaptations have been implemented:

1. Acoustic environment redesign: Installed AcoustiGuard ceiling baffles (2” thick, NRC rating 0.85) and replaced hard-surface rugs with CarpetRight EcoSoft padding (STC 58 rating), reducing ambient noise from 68 dB to 54 dB during free play
2. Visual-first instruction: All group directions now include matching picture cards (created in Boardmaker), and teachers point to visuals while speaking
3. Strategic peer pairing: Soren is consistently partnered with Leo, a verbally advanced peer who models language naturally but does not dominate interaction—validated by peer interaction coding (Child Observation Record, COR)

His individualized activity schedule rotates across five zones: Language Loft (picture cards + voice-output devices), Sensory Corner (weighted blanket, tactile bins), Motor Meadow (obstacle course), Calm Cove (dim lighting, fiber-optic lamp), and Book Nook (high-interest, repetitive texts like Press Here by Hervé Tullet). Time in each zone is tracked using a laminated checklist with Velcro stars—Soren places one star per completed zone, building self-monitoring skills.

Progress Monitoring and Data Collection

Progress is measured biweekly using three objective tools:

• Communication Matrix: Tracks shifts across six communication levels (from pre-intentional to language); Soren moved from Level III (intentional non-symbolic) to Level IV (transitional symbolic) in 10 weeks
• Functional Communication Profile: Records frequency of spontaneous, unrehearsed communicative acts; increased from 1.2 to 4.7 per hour
• Goal Attainment Scaling (GAS): Custom scale targeting “uses 2-word phrases spontaneously 3x/day”; baseline = 0.2x/day; current = 1.8x/day (T-score = +1.2)

What Works—and What Doesn’t—for Soren

Not all interventions yield equal results. Rigorous trial-and-error revealed several ineffective or counterproductive practices:

• Drill-based flashcard practice: Led to avoidance behaviors (turning away, covering eyes) and zero word acquisition over 3 weeks (per parent log)
• Forced verbal imitation: When teachers prompted “Say ‘juice’!” after offering juice, Soren consistently shut down (vocalizations ceased for 2+ minutes; observed in 9/10 trials)
• Overuse of AAC without modeling: Introducing PECS without consistent adult modeling resulted in passive handing of cards without eye contact or vocalization
• Unstructured sensory breaks: Allowing unrestricted access to the sensory corner led to dysregulation—not calming—as Soren lacked internal cues to initiate or end input

In contrast, highly effective approaches share three features: predictability (same visual cue before transitions), embedded motivation (using his love of balls to model “roll”, “bounce”, “big”), and adult responsiveness (immediately honoring all communicative attempts—even grunts—with verbal labels and action). For example, when Soren grunted while reaching for a ball, the teacher responded, “You want the BALL! Here’s the BALL!” and rolled it. Within two weeks, he began pairing “ba” + reach.

His progress underscores a foundational principle in early childhood special education: development is not linear, but it is profoundly responsive to intentional, relationship-based support. Soren’s 11-word gain in four months occurred not because of a single technique, but because every adult in his world—from his pediatrician to his preschool aide—used the same vocabulary, paused with the same rhythm, and celebrated every attempt with the same genuine enthusiasm.

Next Steps and Long-Term Outlook

At Soren’s upcoming 30-month review, goals include: (1) producing 30+ words with 80% intelligibility to unfamiliar adults; (2) combining two words spontaneously in 50% of opportunities; and (3) tolerating auditory transitions (e.g., clean-up song) without ear-covering for 80% of occurrences. His team will reassess eligibility for continued Early Intervention services using Oregon’s Early Childhood Special Education Eligibility Criteria, which requires documented delay in two or more developmental domains OR one domain with functional impact.

Prognosis remains favorable. Population studies (Zhang et al., Pediatrics, 2023) show that toddlers with Soren’s profile—bilingual, strong nonverbal cognition, family engagement, and early AAC exposure—have a 92% likelihood of entering kindergarten with age-appropriate language skills. His bilingual advantage may also confer long-term executive function benefits: research from the University of Washington Institute for Learning & Brain Sciences indicates dual-language learners demonstrate superior inhibitory control by age 5.

Most importantly, Soren’s journey reminds us that developmental timelines are not universal benchmarks—they are personal narratives shaped by relationships, environment, and responsive care. His “more” isn’t just a word; it’s an invitation—to listen more closely, adapt more thoughtfully, and celebrate not just what he says, but how he connects, explores, and insists on being understood. That insistence, expressed through a grunt, a point, or a carefully placed picture card, is the most powerful language of all.

Soren’s story is not about catching up. It’s about meeting him where he is—with data, compassion, and unwavering belief—and building forward, one intelligible word, one regulated breath, one shared smile at a time.

His favorite toy remains the Melissa & Doug Wooden Pound & Tap Bench, where he now taps rhythmically while vocalizing “tap-tap-tap” in rising intonation—his first consistent syllable repetition. That sound, emerging without prompting during independent play, wasn’t captured on any assessment form. But his teacher noted it in her journal on May 3rd: “Soren tapped. And then he said it. Not ‘tap’. But ‘tap-tap-tap’. Like music.”

That’s where development lives—not in percentiles or checklists, but in the spaces between sounds, the pause before a word, and the certainty that every child has something essential to say.

For practitioners: Soren’s case reinforces that standardized scores must be interpreted alongside ecological validity—the real-world contexts where learning and communication happen. A child scoring at the 5th percentile on expressive vocabulary may still initiate 12 joint attention bids in 10 minutes, a skill strongly predictive of later pragmatic language success (Adamson et al., 2019).

For families: Progress is measured in micro-moments—eye contact held for three seconds longer, a grunt followed by a pointing gesture, a picture card handed with palm up instead of flat. These are not small victories. They are the architecture of communication being built, brick by brick.

For policy makers: Soren’s access to timely EI services (evaluated at 25 months, therapy began at 26 months) was made possible by Oregon’s Early Intervention Referral Protocol, which mandates evaluation within 15 calendar days of referral. Nationwide, median wait times exceed 42 days—delaying critical neural plasticity windows.

Soren doesn’t need to speak like everyone else. He needs to be heard like everyone else. And thanks to coordinated, compassionate, evidence-informed support, he is.

His next word—anticipated by his team, his family, and himself—is already forming. Not on a test. But in the space between breath and voice, waiting for the right moment, the right person, and the right kind of listening.
