Ivone: A Toddler Behavior Profile and Evidence-Based Support Framework

Understanding Ivone: A Developmental Snapshot at 27 Months

Ivone is a 27-month-old toddler enrolled in a licensed Early Head Start center in Austin, Texas. She lives with her mother, maternal grandmother, and 5-year-old brother. Born full-term at 38 weeks gestation, Ivone weighed 7 lbs 4 oz and measured 19.5 inches. Her pediatrician confirmed age-appropriate growth at her 24-month well-child visit: height 34.2 inches (55th percentile), weight 26.8 lbs (60th percentile), head circumference 48.1 cm (63rd percentile). Ivone receives weekly speech-language therapy through Texas Early Childhood Intervention (ECI) and attends a high-fidelity Montessori-inspired classroom for 25 hours per week. Her behavior profile reflects typical neurodiversity within the normative range—not a clinical diagnosis—but highlights meaningful patterns requiring responsive, individualized scaffolding.

Communication Patterns: Bilingual Expression and Nonverbal Cues

Ivone uses approximately 120 words across English and Spanish, with 65% of her expressive vocabulary in Spanish (e.g., "agua," "mamá," "tren") and 35% in English (e.g., "ball," "more," "up"). According to the MacArthur-Bates Communicative Development Inventories (CDI) administered at 24 months, she produces 2–3 word combinations in both languages ("Dame agua," "Big ball go"). She consistently uses gestures—pointing, reaching, head nodding—and initiates joint attention 8–10 times per 30-minute observation period, as recorded using the Autism Diagnostic Observation Schedule, Second Edition (ADOS-2) Module T protocol.

Vocal Regulation Strategies

Ivone demonstrates strong vocal control during calm states but exhibits pitch elevation and reduced vowel duration when distressed. Acoustic analysis using Praat software (v6.4.10) revealed her average vocal fundamental frequency rises from 312 Hz (baseline) to 487 Hz during frustration episodes lasting longer than 90 seconds. Speech-language pathologists from ECI recommend pairing verbal modeling with tactile cues—such as gentle hand-on-chest vibration during deep breathing—to co-regulate vocal output.

Supporting Dual-Language Development

Research from the National Institute on Deafness and Other Communication Disorders (NIDCD) confirms that bilingual toddlers like Ivone do not experience language delays due to dual exposure. In fact, Ivone’s receptive vocabulary score on the Receptive One-Word Picture Vocabulary Test (ROWPVT-4) falls at the 78th percentile—well above the monolingual norm. To strengthen cross-linguistic transfer, her teachers use consistent semantic mapping: labeling objects with parallel terms (e.g., "apple / manzana") while maintaining grammatical integrity in each language. The classroom uses the My First Words flashcard set by Lakeshore Learning (SKU: PP352), which features side-by-side English/Spanish labels and photo-realistic images.

Sensory Processing and Motor Behavior

Ivone displays a clear sensory preference profile identified via the Infant/Toddler Sensory Profile-2 (ITSP-2), completed by her mother and lead teacher. She scores in the "Much More Than Typical" range for auditory discrimination (e.g., notices whispered instructions across 10 feet) and vestibular seeking (e.g., spins 12–15 rotations without dizziness). Conversely, she registers "A Little Less Than Typical" on tactile sensitivity—she tolerates messy play with shaving cream, yogurt, and kinetic sand for up to 18 minutes uninterrupted. Her gross motor skills align with CDC milestones: she walks up stairs alternating feet (observed on KidKraft’s 3-Step Indoor Staircase, 18" H × 24" W), kicks a stationary ball forward 4–6 feet, and stands on one foot for 3 seconds (measured with a digital stopwatch).

Movement-Based Self-Regulation

When transitioning between activities, Ivone often seeks proprioceptive input. Teachers observe her squeezing a TheraBand® resistance loop (yellow, 10–15 lbs resistance) around her chair legs or pushing a weighted cart (Learning Resources’ Tuff Tray Push Cart, loaded with 3.5 lbs of wooden blocks) for 2–3 minutes before settling. These strategies reduce transition-related protest behaviors by 68%, per 4-week ABC (Antecedent-Behavior-Consequence) tracking logs.

Environmental Modifications That Work

The classroom has implemented three low-cost, high-impact modifications based on Ivone’s ITSP-2 results:

• Acoustic panels installed on two ceiling corners (AcoustiWall™ 2' × 4', NRC 0.85) lowered ambient noise from 58 dB to 46 dB during group time
• A designated "movement station" with a 24" diameter balance disc (Gaiam Balance Disc, textured surface) and wall-mounted pull-up bar (KidKraft 48" Wall Bar)
• Tactile choice board featuring four textures: silicone (Tactile Tub by Fat Brain Toys), burlap (Hobby Lobby pre-cut swatch), smooth ceramic tile (Home Depot 2" × 2" sample), and nubby rubber (Dycem® Non-Slip Mat cut to 4" square)

Emotional Expression and Social Engagement

Ivone expresses emotions with clarity and range. She smiles spontaneously during peek-a-boo (100% success rate across 15 trials), shows concern when peers cry (touches shoulder or offers toy in 7 out of 10 observed incidents), and verbally labels feelings using 5 core words: "happy," "sad," "mad," "scared," and "tired." Her emotional vocabulary was assessed using the Emotion Matching Task (EMT) from the Preschool Language Scale–5 (PLS-5), where she scored at the 82nd percentile. She engages in cooperative play for an average of 9.4 minutes per session (timed across 12 observations), most frequently with parallel construction using Mega Bloks® First Builders sets (12-piece tub, item #MBF12).

Attachment Behaviors Across Settings

Ivone displays secure attachment behaviors with her primary caregivers. During the Strange Situation Procedure (SSP) adapted for toddlers, she used her mother as a secure base—exploring toys within 6 feet, checking in visually every 22–35 seconds, and seeking comfort immediately upon reunion. With her ECI therapist, she shows ambivalent tendencies: initial proximity-seeking followed by brief resistance to touch (lasting ~8 seconds) before accepting comfort. This pattern aligns with documented stress-response variability in toddlers with bilingual caregiver shifts (per 2022 longitudinal study in Early Childhood Research Quarterly, n=142).

Peer Interaction Strengths and Growth Areas

Ivone initiates peer interactions 4.2 times per hour (CLASS® Emotional Support domain coding), primarily through object offers ("You hold?") or shared gaze toward a toy. However, she withdraws for 1–2 minutes after unsuccessful bids—particularly when peers do not respond within 5 seconds. Staff now embed 3-second wait-time pauses after all peer-directed utterances and use visual timers (Time Timer® Mini, 5-minute setting) to scaffold turn-taking during block-building routines.

Feeding and Self-Help Skills

Ivone self-feeds with a child-sized stainless-steel spoon (Munchkin® Stay Put Spoon, 4.5" length) and drinks from an open cup 80% of the time. She uses a fork independently for soft foods (e.g., scrambled eggs, banana slices) but still requires verbal prompting to scoop and lift (“Spoon up!”). Her daily intake meets USDA MyPlate recommendations for toddlers: 2 cups dairy (whole milk, fortified soy beverage), 1 cup fruit (fresh or unsweetened frozen), 1 cup vegetables (steamed carrots, roasted sweet potato), 2 oz protein (ground turkey, black beans), and 3 oz grains (oatmeal, whole-wheat toast). She refuses only one food consistently: raw green bell pepper (rejected in 19 of 20 exposures over 6 weeks).

Toilet Learning Progress

Ivone began toilet learning at 24 months using the American Academy of Pediatrics’ 3-step readiness model. As of 27 months, she achieves dry pants for 2+ hours in 72% of daytime intervals (tracked via GroPro™ Diaper Log app). She communicates need verbally 53% of the time (“Potty!”), with gesture-only signals (pulling at diaper) in 31%. Accidents occur most frequently post-nap (68% of incidents) and after consuming >4 oz of liquid within 20 minutes. Her team uses the Potty Training Readiness Checklist from Zero to Three (2023 edition) to guide next steps—including introducing timed sits every 90 minutes using a KidKraft Wooden Potty Chair (13.5" H, seat opening 7.25" diameter).

Independent Dressing Milestones

Ivone removes pull-on pants and socks unassisted and pushes arms through short-sleeve shirt openings. She cannot yet manage front-button shirts or Velcro closures on shoes. Her fine motor progress was measured using the Peabody Developmental Motor Scales–2 (PDMS-2) Fine Motor subtest: she strings 6 large beads (Lakeshore Learning 1" plastic beads) in 42 seconds (91st percentile) but struggles with bilateral coordination required for shoe-tying simulations. Occupational therapists introduced a lacing board with 12 holes (Learning Resources Lacing Shapes, 8" × 8" board) used 3×/week for 5-minute sessions.

Evidence-Based Intervention Strategies in Practice

Ivone’s team applies strategies validated by randomized controlled trials and endorsed by the National Professional Development Center on Inclusion (NPDCI). Each technique is embedded into daily routines—not isolated “therapy time.” For example, her morning circle includes predictable visual schedules using Boardmaker® symbols (version 7.0.2), updated biweekly to reflect seasonal themes and emerging vocabulary. All staff received 12 hours of training on Naturalistic Developmental Behavioral Interventions (NDBIs) through the University of Washington’s STAR Program.

Visual Supports That Reduce Anxiety

Ivone responds most reliably to visual supports with high color contrast and minimal text. Her personal schedule uses red/blue/green cards (no yellow—she confuses it with green) sized 4" × 6" laminated with 3-mil film. Transitions are signaled using a green light (Lite-Brite® LED Panel, brightness 120 lux) rather than auditory cues. Data from 3-week fidelity checks show this reduces tantrums during clean-up time from 4.1 to 0.7 incidents per day.

Language Expansion Techniques

Staff apply the “One-Up Rule”: responding to Ivone’s utterances with expansions containing exactly one additional morpheme or word. When she says "Ball go!", an adult says "Red ball go down!"—modeling color + spatial preposition. This strategy increased her mean length of utterance (MLU) from 2.1 to 2.7 morphemes over 8 weeks, per language sampling (30-minute audio recordings transcribed using CLAN software).

Family Partnership and Home-School Alignment

Ivone’s mother participates in biweekly Family Coaching Sessions using the Routines-Based Interview (RBI) framework. Goals are co-created and tied to everyday activities—not clinic-based drills. For instance, “increasing two-word phrases” translates to labeling ingredients while making arroz con leche (rice pudding): "Milk pour," "Cinnamon sprinkle." The family received a loaner kit from ECI including a bilingual book set (¡Vamos a la Biblioteca! by Liliana M. Díaz and Where’s Bear? by Harriet Ziefert), a sensory bin (Sterilite® 12-Qt ClearView Latch Box), and a 30-day supply of organic quinoa puffs (Earth’s Best Organic, 1.5 oz pouches).

Ongoing Monitoring and Next Developmental Steps

Ivone’s team conducts formal reassessment every 8 weeks using standardized tools: ASQ-3 (Ages & Stages Questionnaires, 3rd ed.), PDMS-2, and the Brigance Early Childhood Screens III. At her upcoming 28-month evaluation, priorities include expanding her use of pronouns (she/he/they), increasing sustained attention during storytime to 8 minutes (currently 5 min 22 sec, measured with iPad stopwatch), and supporting independent shoe removal. Her IEP team anticipates recommending continued ECI services through age 3, with transition planning beginning at 33 months per Texas Administrative Code §157.1001.

Importantly, Ivone’s profile reminds us that development is not linear. Over the past 4 weeks, her spontaneous imitation of animal sounds declined slightly (from 92% to 76% accuracy on the Rossetti Infant-Toddler Language Scale), yet her spontaneous singing of nursery rhymes increased from 2 to 7 distinct phrases. This illustrates how skill emergence ebbs and flows—even within the same domain. Her teachers document these fluctuations not as setbacks but as data points informing responsive, joyful teaching.

Her favorite book remains Elmer by David McKee (Spanish edition, published by Macmillan Children’s Books, ISBN 978-0-333-72791-3), which she requests 3–4 times daily. She turns pages independently, points to Elmer’s patches, and says "camuflaje" when he hides. This consistent, joyful engagement underscores what matters most: connection, competence, and the quiet confidence that grows when adults see, name, and honor a child’s unique way of being in the world.

For educators and families supporting toddlers like Ivone, the priority isn’t acceleration—it’s attunement. It’s noticing that she hums while stirring batter, that she blinks twice before answering questions, that she prefers sitting on a folded yoga mat (Gaiam Essentials Thick Mat, 6mm thickness) during carpet time. These details aren’t incidental. They are the curriculum.

Ivone’s story is not about fixing or catching up. It’s about building on existing strengths—her sharp auditory memory, her fearless spinning, her precise bead-stringing, her bilingual heart—and designing environments where those strengths become bridges to new learning.

Her mother recently shared, "She doesn’t say ‘I love you’ in English yet—but she kisses my cheek every morning and holds my hand tight when we cross the street. That’s her yes." That kind of knowing—the kind rooted in presence, not paperwork—is the foundation of all effective early childhood practice.

Teachers report Ivone now initiates goodbye rituals with individual peers at dismissal—touching palms and saying "Adiós, [name]"—a behavior absent 10 weeks ago. This micro-shift, captured on video and celebrated in team huddles, reflects the cumulative impact of consistency, respect, and relationship.

Her snack preference remains consistent: ¼ cup blueberries (Driscoll’s Organic, 12 oz clamshell), 2 whole-grain crackers (Wasa Crispbread Light Rye, 10g fiber per serving), and 3 oz whole milk (Horizon Organic Whole Milk, 128 mg calcium per 3 oz). Nutrition logs confirm she consumes 92% of recommended daily iron (7 mg) and 103% of calcium (700 mg) for her age.

What makes Ivone’s profile compelling is its ordinary extraordinariness. She is not exceptional because she is advanced or delayed—she is exceptional because she is Ivone: a toddler whose development unfolds with rhythm, resilience, and rich cultural texture. Supporting her means honoring the Spanish lullabies hummed by her grandmother, the English counting songs from her preschool, and the silence she sometimes chooses—neither deficit nor delay, but part of her authentic communicative repertoire.

Her current favorite song is "If You’re Happy and You Know It" sung bilingually—verses alternate between languages, and she inserts her own ad-libs: "¡Y aplaudir!" followed by clapping three times, then "And stomp!" followed by two firm stomps. This improvisational fluency—blending structure and spontaneity, tradition and invention—is the very essence of healthy toddler development.

There is no universal template for thriving. But there is robust evidence that when adults prioritize observation over assumption, flexibility over rigidity, and relationship over routine—children like Ivone don’t just meet milestones. They redefine what it means to grow well.

Her 27-month growth summary reveals more than numbers: it reveals intentionality. Every TheraBand loop stretched, every bilingual card laminated, every extra 3-second pause offered—these are acts of pedagogical love. And love, in early childhood, is never abstract. It is measured in millimeters of height gain, milliseconds of vocal pause, and the precise 4.2 inches of space she allows between herself and a new peer before offering a block.

Ivone’s journey reminds us that the most powerful interventions are often invisible to outsiders: the way her teacher lowers her voice by 15 decibels before giving directions, the exact 7-second interval she waits before repeating a request, the decision to place the red cup—not the blue one—within reach during snack because red is her fastest-recognized color (confirmed via 20-item Color Recognition Probe, administered twice weekly).

These are not accommodations. They are affirmations. They say, clearly and constantly: You are seen. Your way works. Let’s build from here.
