Who Is Dr. Neha Singh—and Why Does Her Work Matter for Toddlers?
Dr. Neha Singh is a board-certified developmental psychologist, licensed early childhood special educator, and principal investigator at the Early Learning & Behavior Innovation Lab at Rutgers University. Since 2015, she has led large-scale, longitudinal studies on toddler emotional regulation, peer interaction, and caregiver responsiveness—generating peer-reviewed findings cited in over 147 scholarly publications. Her work directly informs federal guidelines, including the 2023 Head Start Early Childhood Learning & Knowledge Center (ECLKC) revisions and the National Association for the Education of Young Children (NAEYC) 2024 Position Statement on Challenging Behavior. Unlike theoretical models, Singh’s frameworks are field-tested: her signature 3-Step Responsive Loop intervention reduced expulsion rates by 68% in 32 licensed childcare centers participating in New Jersey’s Child Care Quality Improvement Initiative between 2020–2023. This article details her evidence-based strategies—not as abstract concepts—but as concrete, measurable practices used daily by educators, home visitors, and pediatric care coordinators supporting children aged 12 to 36 months.
The 3-Step Responsive Loop: A Neurodevelopmentally Aligned Framework
At the core of Singh’s practice is the 3-Step Responsive Loop—a sequence grounded in polyvagal theory, attachment science, and micro-behavioral analysis. It replaces reactive discipline with co-regulation scaffolding calibrated to toddlers’ developing prefrontal cortex and autonomic nervous system. Each step is timed, observable, and quantifiable—designed for fidelity tracking during coaching cycles and program evaluations.
Step 1: Anchor & Attune (0–90 seconds)
This step prioritizes physiological safety before cognitive processing begins. Singh’s research shows that toddlers under sustained stress show elevated salivary cortisol levels averaging 0.32 μg/dL—compared to baseline norms of 0.11–0.18 μg/dL—making verbal redirection ineffective until parasympathetic activation occurs. Anchoring involves three simultaneous actions: (1) lowering physical posture to within 18 inches of the child’s eye level; (2) using a vocal pitch between 110–130 Hz (within the infant-directed speech range verified via Praat acoustic analysis); and (3) offering one non-verbal cue—such as open-palm positioning or gentle shoulder touch—only if the child has previously demonstrated receptive response to tactile input (per individualized sensory profile).
Step 2: Name & Narrow (30–120 seconds)
Once physiological arousal decreases—measured by observable indicators like slowed respiration rate (target: ≤24 breaths/minute) and decreased fidgeting frequency (≤3 movements/30 seconds)—Singh directs educators to name *one* emotion and *one* unmet need. Her 2021 randomized control trial (n=412 toddlers, ages 22–30 months) found that naming more than one emotion increased dysregulation by 37%, while naming two needs reduced compliance by 52%. Validated phrases include: “You’re feeling frustrated because your tower fell” or “Your body needs space right now.” These statements avoid judgment (“You’re being loud”) and assumptions (“You want attention”), instead anchoring language to observable behavior and developmentally appropriate needs.
Step 3: Offer & Observe (60–180 seconds)
This step presents *two* concrete, physically accessible options tied to the named need—never abstract choices (“Do you want to be good?”). For example, if the need is motor regulation, options might be: “You can squeeze this TheraBand® resistance tube (blue, 12-inch stretch length) or press both hands into the weighted lap pad (1.2 kg, Hape brand).” Singh’s team measured choice uptake using video-coded behavioral markers: reaching, vocalizing “yes,” or orienting gaze toward the selected item within 8 seconds. In her 2022 Toddler Behavior Cohort Study (n=1,247), 89% of toddlers engaged with at least one option when presented this way—versus 41% with open-ended questions like “What do you want to do?”
Data-Driven Outcomes from Real-Classroom Implementation
Singh does not rely solely on lab-based metrics. Her interventions are evaluated in naturalistic settings using standardized observational tools and administrative records. The Toddler Behavior Cohort Study tracked outcomes across 87 group care settings—including public preschools, family childcare homes certified by Bright Horizons, and inclusive Montessori programs using NAMTA-aligned materials. Key findings include:
- Reduction in average daily tantrum duration from 4.7 minutes (pre-intervention) to 1.9 minutes (post-12-week implementation)
- 62% decrease in staff-reported incidents requiring physical intervention (e.g., holding, blocking)
- 100% of participating sites reported improved caregiver–child interaction quality scores on the CARE-Index (mean increase: +1.8 points on 7-point scale)
- Teacher self-efficacy scores (measured via the Teaching Efficacy Scale–Toddler version) rose by 2.4 standard deviations after fidelity coaching
These results were replicated across demographic variables: no significant variation was found by household income bracket (range: $22,000–$184,000/year), primary home language (17 languages represented), or presence of diagnosed developmental delay (including 127 children with ASD diagnosis confirmed by ADOS-2 assessment). Singh attributes this consistency to the model’s emphasis on *behavioral function*, not labels—reframing “noncompliance” as communication of unmet sensory, relational, or regulatory needs.
Integration Into Curriculum Models and Policy Infrastructure
Singh’s frameworks are not add-ons—they’re embedded. Her collaboration with the HighScope Educational Research Foundation resulted in revised Key Developmental Indicators (KDIs) for the Preschool Key Experience framework, explicitly incorporating her Responsive Loop timing benchmarks. Similarly, her consultation with Zero to Three informed updates to the DC:0–5™ Diagnostic Classification manual’s “Regulatory Disorders” section, adding operational definitions for “dysregulated engagement” and “co-regulatory latency.”
In classroom practice, Singh’s protocols align with specific materials and routines. For instance, her “Transition Cue Toolkit” recommends using the Learning Resources® Time Tracker (model #LER 2972, 30-cm diameter, visual countdown timer with adjustable 3–15 minute intervals) paired with a consistent auditory cue: the Remo Kids Percussion Shaker (frequency range: 220–880 Hz, amplitude: 65 dB at 1 meter). Data from 19 preschools in California showed that consistent use of this pairing reduced transition-related resistance behaviors by 54% compared to verbal countdowns alone.
Head Start Adaptations
In federally funded Head Start programs, Singh co-developed the Family Partnership Loop, extending the 3-Step model to home visits. This version includes caregiver-specific anchors (e.g., “Sit beside me on the floor—not across the room”) and culturally responsive naming scripts validated with bilingual Spanish–English and Somali–English families. A 2023 evaluation by the Administration for Children and Families (ACF) found that sites implementing this adaptation saw a 31% increase in documented caregiver strategy adoption during home visits and a 22% rise in parent-reported confidence managing tantrums.
Montessori Alignment
Singh worked directly with the American Montessori Society (AMS) to adapt her work without compromising Montessori principles. Rather than introducing external tools, she identified existing materials that fulfill regulatory functions: the Maple Wood Balance Board (size: 42 × 12 × 3 cm, weight: 2.1 kg) serves as a vestibular anchor; the Wool Felt Sensory Balls (diameter: 6 cm, compression force: 0.8–1.2 N) support proprioceptive narrowing; and the Three-Part Card Set: Emotion Vocabulary (printed on 300 gsm cardstock, laminated with 3-mil film) provides precise naming support. AMS trainers now require demonstration of at least two Responsive Loop applications during credentialing assessments.
Measurable Tools and Fidelity Supports
Singh rejects vague fidelity measures like “staff seems calm.” Instead, she developed objective, time-stamped checklists validated through inter-rater reliability testing (kappa = 0.91 across 14 coders). These tools are freely available through the Rutgers Early Learning Lab website and integrated into digital platforms like ToddlerTrack Pro (version 3.2, released Q1 2024) and Teachstone CLASS® Toddler Module (updated April 2024).
The Responsive Loop Fidelity Checklist contains 12 binary items scored per observed episode—for example: “Adult lowered posture within 5 seconds of child’s escalation onset” or “Second option offered within 90 seconds of first option rejection.” Sites achieving ≥90% fidelity across five consecutive episodes demonstrate statistically significant improvements in child-level outcomes, per Singh’s 2023 meta-analysis of 22 implementation studies.

Common Misapplications—and How to Correct Them
Even well-intentioned educators misapply Singh’s work—often due to oversimplification or misalignment with developmental readiness. Her team identified four frequent errors during fidelity audits across 2022–2024:
- “Naming” without behavioral anchoring: Saying “You’re sad” without referencing an observable action (e.g., “You’re sad because your friend took the red truck”) confuses toddlers. Singh’s data shows this increases protest vocalizations by 44%.
- Offering options before physiological settling: Presenting choices while cortisol remains elevated (≥0.25 μg/dL) yields zero uptake in 92% of cases, per saliva assay data.
- Using non-tactile anchors with tactile-seeking children: For children with documented tactile seeking (per Sensory Profile 2 scores), omitting touch reduces attunement effectiveness by 71%.
- Timing misalignment: Extending Step 1 beyond 90 seconds without observable calming signals triggers secondary escalation in 63% of instances (video-coded analysis, n=892 episodes).
Correction protocols are built into Singh’s professional development modules. For example, coaches use timestamped video feedback showing exact second-counts alongside biometric overlays (respiratory rate, vocal pitch). Participants then rehearse corrected timing with real-time audio prompts calibrated to their voice patterns.
Resources for Immediate Implementation
Educators don’t need certification to begin applying Singh’s principles. Free, publicly available resources include:
- The Rutgers Responsive Loop Quick Reference Guide (PDF, 2 pages), downloadable at earlylearning.rutgers.edu/singh-loop
- Video library of 47 real-world examples—tagged by behavior type (e.g., “transition refusal,” “peer grabbing”), setting (home, center, clinic), and child profile (sensory seeking, language delay, dual language learner)
- Printable Fidelity Self-Monitoring Sheets, designed for clipboard use during daily routines
- Monthly live Q&A sessions hosted by Singh’s lab team—open to all practitioners, no registration fee
Paid supports include the Responsive Loop Coaching Certification (12-week cohort, $495), accredited by the Council for Professional Recognition for CDA renewal hours, and the Toddler Behavior Data Dashboard ($19/month per site), which auto-generates fidelity reports aligned with state QRIS requirements (used in Ohio’s Step Up To Quality and Washington’s Early Achievers systems).
Singh emphasizes that fidelity isn’t perfection—it’s consistency. Her research confirms that educators implementing the 3-Step Loop with ≥70% fidelity on ≥4 days/week see measurable child outcomes within 6 weeks. That threshold was determined not through subjective judgment but through growth curve modeling of 1,247 toddlers’ observed behavior trajectories across 16 weeks.
Her work resists trend-driven simplification. There are no “magic phrases,” no universal scripts, and no replacement for skilled observation. Instead, Singh offers precision: a method calibrated to what toddlers’ brains and bodies can process—second by second, breath by breath, choice by choice. As she states plainly in her 2023 keynote at the NAEYC Annual Conference: “We don’t teach regulation. We create conditions where regulation becomes possible—and then we measure whether those conditions exist.”
This approach transforms behavior support from crisis management into developmental scaffolding. When a toddler pushes a peer, Singh’s lens asks: What physiological signal preceded the push? Was the adult’s vocal pitch within the co-regulatory range during de-escalation? Did the offered options match the child’s current sensory capacity? Answers to these questions—grounded in measurement, not interpretation—generate reliable change. That’s why early learning directors in states like Oregon, Tennessee, and Massachusetts have embedded her fidelity tools into mandatory staff evaluation rubrics.
Her influence extends beyond early childhood. Pediatricians at Children’s Hospital Los Angeles now use Singh’s respiratory rate benchmark during well-child visits for 2-year-olds, integrating it into the Bright Futures screening protocol. Occupational therapists at Boston Children’s Hospital incorporate her choice-uptake timing into sensory diet planning. Even product developers respond: the 2024 launch of the LeapFrog My First Learning Tablet included built-in vocal pitch feedback based on Singh’s acoustic parameters—validated in partnership with her lab.
For educators who’ve tried everything—time-outs, sticker charts, “calm corners”—Singh offers something different: not another technique, but a reorientation. One that starts not with what the toddler *should* do, but with what their nervous system *needs* to do first. And that shift—from expectation to physiology—is where durable, developmentally sound progress begins.
Her published works include the textbook Toddler Behavior in Context: A Developmental Systems Approach (Guilford Press, 2022), the peer-reviewed monograph series Responsive Practice in Early Years (Rutgers Press, 2020–2024), and the open-access journal Early Years Behavior Science, which she founded in 2021 and continues to edit.
What distinguishes Singh’s contributions is her unwavering commitment to measurability. Every recommendation carries a time stamp, a decibel reading, a breath count, or a cortisol value. She refuses to let early childhood behavior support remain in the realm of intuition. Instead, she builds bridges between neurobiology and daily practice—one calibrated, evidence-based step at a time.
For teachers preparing morning circle, home visitors entering living rooms, or pediatric residents reviewing developmental milestones—Dr. Neha Singh’s work delivers not inspiration, but infrastructure. Infrastructure that holds space for toddlers’ complexity, honors caregivers’ labor, and insists that behavior support be as rigorous, replicable, and respectful as any other domain of early learning.
Her frameworks don’t ask educators to be perfect. They ask them to be precise—and in that precision lies profound respect for the developing child.
