the research behind the work.

The framing of big feelings as a nervous-system event, with the child borrowing the teacher's calm through tone, breath, and body, draws on Stephen Porges's polyvagal theory of how social engagement and safety cues regulate the autonomic nervous system.

The 'kids do well if they can' framing and the move from consequences to skill-building during hard moments comes from Greene's CPS model, which treats challenging behavior as a lagging skill, not willful defiance.

The 'tired body, hungry body, overstimulated body' framing during long classroom days follows Gunnar's research on early childhood stress reactivity and how a present caregiver buffers the HPA-axis response.

The emphasis on play as the primary mode of learning in the conference notes is grounded in the National Association for the Education of Young Children's DAP position statement, the field's foundational practice guidance.

The framing of dramatic play and storytelling as serious cognitive and social work draws on Paley's decades of classroom research with preschoolers at the University of Chicago Lab School.

The 'just a little above where they are now' framing for next-step goals follows Vygotsky's ZPD from Mind in Society, the gap between what a child can do alone and what they can do with a skilled partner.

The five strands used in conference notes (self-awareness, self-management, social awareness, relationship skills, responsible decision-making) follow the CASEL framework, the most widely adopted SEL model in U.S. schools.

The framing of the teacher as a secure base during drop-off and a safe haven during distress draws on Ainsworth and Bowlby's foundational attachment research.

The tiered approach (nurturing relationships, supportive environments, social-emotional teaching, individualized intervention) follows the Pyramid Model from the Center on the Social and Emotional Foundations for Early Learning.

Language observations and referral guidance follow the American Speech-Language-Hearing Association's communication milestones and the indicators for when a speech-language evaluation is warranted.

The emphasis on serve-and-return conversation, even with very early talkers, draws on Snow's Harvard research showing that conversational turns predict later vocabulary and reading more than total words heard.

The early-literacy indicators used in conferences (alphabet knowledge, phonological awareness, print awareness, oral language) come from the National Early Literacy Panel's meta-analysis of predictors of later reading.

The 'connect before you redirect' and 'name it to tame it' framing in the behavior guide draws on Siegel's interpersonal neurobiology and his model of upstairs and downstairs brain during big feelings.

The 'regulate, relate, reason' sequence used in the behavior guide follows Perry's Neurosequential Model of Therapeutics: a dysregulated child cannot access reasoning until the lower brain feels safe.

The use of safe-place corners, breathing visuals, and 'I'm going to keep you safe' language reflects Bailey's Conscious Discipline approach to building self-regulation through the adult's own state.

The choice to skip sticker charts and behavior clips, and instead describe what the child is working toward, draws on Kohn's research synthesis on the long-term costs of extrinsic reward systems for young children.

The 'tell the child what is about to happen, then wait' framing for diapering, hand-washing, and transitions draws on Gerber's Resources for Infant Educarers principles of respectful, predictable caregiving.

The framing that a hard drop-off is not a failure of attachment but often a sign of it draws on Ainsworth's strange-situation research on how securely attached children protest separation and recover with a trusted adult.

The conference structure (strengths first, shared observations, what school is doing, what the family can mirror at home) reflects Epstein's framework on two-way family-school partnership from Johns Hopkins.

The framing of parents as expert partners, not audiences, follows Mapp's Dual Capacity-Building Framework, the U.S. Department of Education's reference model for family engagement.

The careful word-choice guidance and the rejection of labels like 'difficult' or 'fussy' in conference language draws on Delpit's writing on how teacher language shapes how families of color hear school feedback.

The inclusive-classroom language and the framing that every child gets the support they need to participate follows the Division for Early Childhood's Recommended Practices for working with young children with disabilities.

The framing of behavior as the tip of the iceberg, with sensory and nervous-system needs underneath, draws on Delahooke's clinical work translating polyvagal and sensory-integration research for early childhood settings.

The guidance on when and how to suggest a developmental evaluation to a family is grounded in the U.S. Individuals with Disabilities Education Act and its early-childhood entitlements.

The premise that early relationships in the classroom can buffer toxic stress draws on the original Adverse Childhood Experiences study and the CDC's ongoing public-health work on ACEs and resilience.

The 'one stable, caring adult' framing used in the behavior guide is grounded in Harvard's Center on the Developing Child synthesis on toxic stress, resilience, and the buffering role of relationships.

The trauma-sensitive classroom guidance, including predictable routines, choice, and avoiding shame-based correction, follows the National Child Traumatic Stress Network's school-personnel resources.

The framing that climbing, jumping, and rough-and-tumble play build competence (not danger) follows Sandseter's research identifying the six categories of risky play that support healthy child development.

The emphasis on outdoor time and nature-based learning in the classroom-life observations draws on Louv's synthesis of research on nature exposure and child development.

The framing of early relationships and serve-and-return interactions as the literal architecture of the developing brain follows the National Scientific Council's working papers out of Harvard's Center on the Developing Child.

The framing of working memory, flexible thinking, and self-control as skills that get built through everyday play (not behavior to be corrected) follows Harvard's executive function research.

The infant and toddler framings, including temperament, sleep, and feeding language used in handoffs, draw on Zero to Three, the leading U.S. nonprofit translating developmental science for the first three years.
