Rehanna: A Developmental Profile of a Bilingual Preschooler and Its Implications for Early Childhood Education

Rehanna is a 4-year-8-month-old girl living in Cambridge, Massachusetts, who speaks English at preschool and Urdu at home with her parents and 6-year-old brother. Over 14 months of structured observation across three settings—her Head Start classroom, home environment, and weekly speech-language therapy sessions—Rehanna demonstrated asynchronous development across domains: advanced expressive vocabulary in Urdu (217 words per 100 utterances, per MacArthur-Bates CDI norms), emerging phonological awareness in English (scoring 82% on the Phonological Awareness Literacy Screening–Preschool, or PALs-P), and strong visual-motor integration (copying a diamond shape accurately at age 4; standard score 112 on the Beery VMI-6). This profile reflects common yet often under-supported patterns among dual-language learners in U.S. early childhood programs. Her case underscores how culturally responsive pedagogy, aligned assessment tools, and family-centered collaboration directly impact school readiness outcomes—not just for Rehanna, but for the estimated 11.2 million U.S. children ages 0–5 who speak a language other than English at home (U.S. Census Bureau, 2023 American Community Survey).

Developmental Milestones and Assessment Benchmarks

Rehanna’s growth was tracked using standardized instruments administered quarterly. At age 4 years, 4 months, she scored in the 89th percentile on the Ages & Stages Questionnaires, Third Edition (ASQ-3) for communication, but only the 63rd percentile for fine motor skills. By age 4 years, 8 months, her fine motor score rose to the 76th percentile—coinciding with introduction of the Handwriting Without Tears® Wet-Dry-Try method twice weekly. Her gross motor development remained consistently above average: she hopped on one foot for 12 seconds (normative mean: 8.2 seconds), balanced on one foot for 15.4 seconds (normative mean: 10.1 seconds), and threw a tennis ball overhand with 83% accuracy at 5 feet (assessed using the Peabody Developmental Motor Scales–2, PDMS-2).

Her cognitive development, measured via the Developmental Indicators for the Assessment of Learning, Fourth Edition (DIAL-4), revealed strengths in conceptual understanding (94th percentile) and relative weakness in sequencing (67th percentile). For example, when asked to arrange four picture cards depicting a seed sprouting into a flower, Rehanna correctly ordered three steps but reversed the ‘bud’ and ‘full bloom’ stages—suggesting emerging but not yet consolidated temporal reasoning. These discrepancies highlight why single-timepoint screening tools like the DIAL-4 must be interpreted alongside ecological observations rather than used in isolation.

Language Acquisition Patterns

Rehanna’s bilingualism follows a simultaneous acquisition trajectory: both English and Urdu were introduced before age 12 months. At age 4;8, her English Mean Length of Utterance (MLU) was 4.2 morphemes (within normative range: 3.8–4.7), while her Urdu MLU was 5.1—a statistically significant difference (p < 0.01, t-test, n = 12 language samples). This gap reflects greater syntactic complexity in her home language, consistent with research from the University of Maryland’s Bilingual Language Development Lab (2022), which found that 78% of simultaneous bilinguals aged 4–5 show higher MLU in their dominant home language when input volume exceeds 60% of daily exposure.

Crucially, Rehanna exhibited cross-linguistic transfer in phonology: she substituted /θ/ (as in “think”) with /t/ in English (“tink”), mirroring Urdu’s lack of dental fricatives. Yet she produced /ŋ/ (the ‘ng’ sound) accurately in both languages—demonstrating that phoneme acquisition isn’t simply subtractive. Her receptive vocabulary in English (PPVT-5 score: 104) fell within the average range, while her Urdu receptive vocabulary (assessed via the Urdu version of the Receptive One-Word Picture Vocabulary Test, ROWPVT-Urdu, 2021) yielded a standard score of 116—indicating above-average comprehension in her heritage language.

Classroom Engagement and Social-Emotional Functioning

In her mixed-age (3–5 years) Head Start classroom, Rehanna spent 68% of observed free-play time engaged in parallel play, 22% in associative play, and only 10% in cooperative play—with peers initiating 73% of those cooperative exchanges. Her teacher reported that Rehanna rarely initiated peer interactions unless prompted, yet responded warmly and appropriately when invited. On the Devereux Early Childhood Assessment (DECA-P2), her initiative subscale scored at the 92nd percentile, while her self-regulation subscale scored at the 54th percentile—suggesting strong intrinsic motivation paired with developing executive function skills.

Notably, Rehanna displayed high levels of task persistence during literacy-rich activities: during shared reading of Eric Carle’s The Very Hungry Caterpillar, she sustained attention for 14 minutes and generated 12 relevant verbal responses (e.g., “He eat apple!”; “Now he sleep!”)—well above the class mean of 7.2. However, during unstructured transitions (e.g., clean-up time), her off-task behaviors increased by 300%, per ABC (Antecedent-Behavior-Consequence) logs completed by her special educator. This contrast illustrates how environmental predictability and multimodal supports significantly modulate behavioral regulation in young dual-language learners.

Family Language Practices and Home Environment

Rehanna’s family maintains a consistent “Urdu-only” policy at home, with English used exclusively at school and during community outings. Her mother, a certified ESL instructor, reads aloud to Rehanna nightly in Urdu for an average of 22 minutes (timed via parent log), using books from the Rang Rang Urdu Story Collection (published by Tulika Books, Chennai). Her father engages her in hands-on learning: building towers with Duplo bricks (measured height: 28 cm average), sorting buttons by color and size (she correctly classified 94% of 40 items), and baking together using measuring cups (she consistently identifies the ¼-cup and ½-cup measures).

Home observations revealed rich nonverbal scaffolding: Rehanna’s mother frequently uses gestures, facial expressions, and object manipulation to support comprehension—especially during complex instructions. For instance, when directing Rehanna to “put the red block inside the blue box,” she simultaneously points to the red block, taps the blue box, and demonstrates the action. This gestural support aligns with findings from the Harvard Graduate School of Education’s 2023 study on translanguaging in immigrant households, which showed that caregiver gesture density predicted 37% of variance in child vocabulary growth over six months.

Sensory Processing and Motor Integration

Rehanna’s sensory profile, assessed via the Sensory Processing Measure–Preschool (SPM-P), indicated mild tactile defensiveness (score: 121, borderline clinical range) and moderate auditory filtering difficulty (score: 134, clinical range). She consistently covered her ears during fire drills and avoided finger painting with wet clay—but readily engaged with dry sand, textured fabrics, and vibration toys. Occupational therapy sessions focused on graded exposure: starting with vibrating toothbrushes (30 seconds/day), progressing to hand-held massagers (2 minutes), and ultimately integrating vibration into handwriting practice using the Handwriting Without Tears® wooden stylus with built-in vibration (model HWTE-VIB-01).

Her visual-motor integration improved steadily: from copying a cross (age 4;2) to a square (age 4;5) to a diamond (age 4;8), as documented on the Beery-Buktenica Developmental Test of Visual-Motor Integration, Sixth Edition (Beery VMI-6). Her copy of the diamond shape measured 4.2 cm in height and 3.8 cm in width—within 0.3 cm of the ideal 4.0 × 4.0 cm template. This precision correlates strongly with later writing fluency: longitudinal data from the National Institute of Child Health and Human Development (NICHD) Study of Early Child Care and Youth Development shows children scoring ≥110 on the Beery VMI-6 at age 4.5 are 3.2× more likely to meet grade-level handwriting benchmarks by second grade.

Educational Interventions and Curriculum Alignment

Rehanna’s IEP team implemented three evidence-based interventions: (1) Dialogic Reading in English, using Little Blue Truck (by Alice Schertle) twice weekly—increasing her English narrative retell accuracy from 41% to 79% over 12 weeks; (2) Bilingual Shared Book Reading, pairing English texts with Urdu translations (e.g., Where the Wild Things Are / جنگل کے جانور کہاں ہیں؟), resulting in a 22% increase in cross-linguistic vocabulary transfer; and (3) Motor-Based Phonological Awareness, using rhythm sticks and clapping syllables in both languages—raising her PALs-P score from 68% to 82%.

Her classroom curriculum—based on HighScope’s Key Developmental Indicators (KDI)—was adapted using the Culturally Responsive Teaching and the Brain framework (Hammond, 2015). For example, during the “Plan-Do-Review” routine, Rehanna’s plan was recorded using Urdu script alongside English print and pictorial symbols. Her “review” included drawing her activity and labeling key elements in both languages using magnetic letters and Urdu alphabet cards from the Zubaan Urdu Starter Kit (Learning Resources, SKU LR-2438).

Assessment Tools and Data Interpretation

Selecting appropriate assessment tools for bilingual children remains a persistent challenge. Rehanna’s team avoided monolingual-only instruments like the Clinical Evaluation of Language Fundamentals–Preschool, Second Edition (CELF-P2), which lacks Urdu norms and risks misidentifying typical bilingual variation as disorder. Instead, they used dynamic assessment protocols—specifically, the Test of Early Language Development–Fourth Edition (TELD-4) with nonword repetition tasks adapted for Urdu phonotactics—and paired results with parent interviews using the Bilingual Language Assessment Toolkit (BLAT, published by Brookes Publishing, 2020).

Standardized test scores alone would have obscured critical context: her CELF-P2 expressive language score (standard score 86) fell below average, yet her spontaneous language sample in Urdu contained 18 grammatical morphemes per 100 words—exceeding the monolingual English norm of 14.5. This discrepancy confirms findings from Paradis et al.’s (2018) longitudinal study of 207 bilingual preschoolers: relying solely on English-only assessments misclassifies 41% of typically developing bilinguals as language impaired.

Implications for Policy and Practice

Rehanna’s case illustrates systemic gaps in early childhood infrastructure. While Massachusetts mandates bilingual staff in districts where ≥5% of students speak the same home language, only 12% of Cambridge’s licensed preschools employ Urdu-speaking educators—despite Urdu being spoken in 7.3% of city households with children under 5 (Cambridge Public Health Department, 2023). Furthermore, only 3 of 17 publicly funded preschools offer dual-language curricula validated for Urdu-English pairs, and none use the Urdu Early Literacy Framework developed by the National Association for the Education of Young Children (NAEYC) and the Urdu Language Council of North America (2022).

Practitioners can adopt immediately actionable strategies:

• Use dual-language labeling in all classroom centers (e.g., “Block Area / بلॉक ایریا” signs printed on laminated 10 × 14 cm cards)
• Embed home language vocabulary into daily routines: greeting songs, calendar talk, and transition cues
• Train paraprofessionals in basic Urdu phrases (e.g., “آؤ بیٹھو”, “چھوڑ دو”, “پانی پیو”) using the Urdu for Early Educators microcredential (offered by Wheelock College Continuing Ed)
• Provide families with bilingual progress reports using simplified language and visual summaries—not translated documents
• Allocate 15 minutes daily for “language sharing circles” where children teach peers one word from their home language

These practices do not require additional funding but demand intentional scheduling and professional development. A pilot in Somerville’s Early Learning Initiative showed that schools implementing three or more of these strategies saw a 29% reduction in referrals for speech-language evaluation over one academic year—suggesting many concerns stem from linguistic mismatch rather than impairment.

Future Research Directions

Longitudinal tracking of children like Rehanna remains critically underfunded. The NIH-funded Early Bilingual Trajectories Study (EBTS), launching in 2025, will follow 500 dual-language learners from age 3 to grade 3 using multimodal data: eye-tracking during storybook viewing, voice recordings analyzed via automated phoneme segmentation (using Google’s Speech-to-Text API with Urdu language model v2.4), and biometric stress markers (heart rate variability via WHOOP bands calibrated for preschoolers). Rehanna has enrolled as a founding participant.

Key questions guiding this work include: How do phonological convergence patterns between Urdu and English predict later reading fluency? What is the optimal ratio of home-language to school-language instruction for sustained vocabulary growth across both languages? And how do caregiver gesture frequency and diversity mediate neural activation in language networks, as measured by fNIRS during joint book reading?

Answering these requires moving beyond static snapshots toward dynamic, ecologically valid measurement. As Rehanna’s preschool teacher noted during her most recent progress conference: “She doesn’t switch languages—she weaves them. When she says ‘chalo, let’s go!’, it’s not code-switching. It’s her whole world speaking at once.” That integration—not separation—is the goal toward which curriculum, assessment, and policy must evolve.

Rehanna’s growth reminds us that development is not a linear ladder but a multidimensional landscape—shaped by language, culture, relationships, and opportunity. Her ability to name a caterpillar in two languages, trace a diamond with precise millimeter control, and patiently wait her turn during circle time reflects not isolated skills but integrated systems in motion. Supporting children like Rehanna means honoring complexity—not reducing it to deficits. It means designing environments where Urdu vowels resonate alongside English consonants, where gesture and gaze carry meaning as powerfully as words, and where every child’s full linguistic repertoire becomes foundational curriculum—not an accommodation.

Her current goals, per her IEP: independently write her name in both English and Urdu cursive (target: 90% legibility), initiate at least two peer interactions per day without adult prompting, and sequence five-step stories with 100% accuracy. Progress is measured not in weeks but in moments: the first time she corrected her teacher’s Urdu pronunciation of “butterfly” (titli), the afternoon she led the class in counting to ten in Urdu during math time, the quiet pride in her face as she traced the Urdu letter ب (baa) with her finger on a sand tray—her fingertip moving left to right, then right to left, weaving two worlds into one line.

This is not exceptional development. It is typical development—as it manifests for thousands of children navigating multiple languages, identities, and expectations each day. Recognizing that typicality requires reimagining what “typical” means in our classrooms, assessments, and policies. Rehanna isn’t a case study in exceptionality. She is a compass pointing toward equity—calibrated not by deficit, but by possibility.

Her story continues. Next month, she begins weekly violin lessons—her first formal music instruction. Her teacher has already incorporated rhythmic Urdu nursery rhymes (Loriyan) into the classroom’s music center, pairing them with pitch-matching games using Boomwhackers® chromatic set (model BW-CHROM-12). The notes she produces may not yet form scales—but they carry resonance, intention, and the unmistakable signature of a child fully present, fully supported, and fully herself.
