POSITIVE SOCIAL CLIMATE: A welcoming community of support. Fulfills the need for sense of BELONGING.
What to do:
• After birth, plan a “laying in” where other mothers wait on you and your baby. This was common practice in traditional societies.
• Get a community of support together for you and your child (ideally other adult relatives are supportive of helping provide the evolved nest).
Human mothers evolved to have a built-in safety net of other adult support (Hrdy, 2009). Supportive social contact is known to be a positive influence during birthing and post-natal mother-child communication (Klaus & Kennel, 1976), and in fact, three attentive adults (parents and/or alloparents) appear to be optimal for children to thrive (Sagi et al., 1995; van Ijzendoorn, Sagi, & Lambermon, 1992).
We evolved big social brains that develop mostly after birth. Because newborns have only 25% or less of adult brain volume, they need a supportive environment to maintain a growth-encouraging biochemistry during the first years of life when their brain more than triples in size. Frequent breastfeeding provides a wash of appropriate hormones, immunoglobulins and other elements that build healthy brain and bodies.
But minimizing distress is also important as extensive stress mobilizes cortisol, which at high levels destroys brain connections and signals danger, undermining growth generally. Stress during gestation and/or early life are particularly detrimental to mammals, shaping antisociality instead (Sandi & Heller, 2015).
To grow their fullest capacities, young children expect the deep social immersion in a welcoming community from the beginning of life, including conception. Babies evolved to be bathed in loving attention by a village of caregivers (Hrdy, 2009). for joy, for face-to-face body to body immersion in social experience. Such experiences nourish us, help us grow and stay healthy.
The evolved nest provides a welcoming, sustaining affectionate climate for a child (Tarsha & Narvaez, 2019). Within the nest children form secure, responsive relationships with adults and peers; extensive opportunities for free movement, self-directed play and learning; integration into the local landscape and bonding with and contribution to the neighborhood; multiple and multi-aged mentors that encourage the interests and gifts of the child; immersion in the natural world to build ecological knowhow, ecological attachment and respectful relations with the other than human; routine healing practices such as restorative justice practices and ceremonies to honor the cycles of life; and regular joyous group activities such as song games, dancing and dramatic invention.
What is it about the evolved nest that makes it ideal for raising a healthy, cooperative, happy child? Recall that human infants resemble fetuses until about 18 months of age, so all aspects of brain and body development are still under construction and highly malleable from experience.
The viscera, which includes the vagus nerve and immune system, are part of what is being “trained up” or conditioned by early experience. In fact, the dynamic bodies of mother and child are set to interlock at naturalistic birth when body reward systems are primed to engage deeply with one another (Buckley, 2015).
Clinician Martha Welch (Welch & Ludwig, 2017) identified one of the ongoing aspects of conditioning that occurs through responsive affectionate care between mother and infant. It is a subcortical visceral/autonomic co-conditioning, which is a key physiological aspect of bonding and mutual co-regulation upon which a child’s emotional connection and health depend.
Under species normal conditions, the child and mother are mutually attracted from the beginning and form emotional connections at the visceral level. Repeated episodes of shared sensory contact lead to robust visceral/autonomic conditioning. In species-normal settings, the child is frequently co-regulating with mother and other responsive, physically and emotionally connected caregivers.
In species-atypical settings, as in modern societies, the child is separated from primary caregivers for hours at a time. This leads to routine dysregulation with little opportunities to restore co-regulation, creating toxic stress. The mother and child can become repelled by instead of attracted to one another and the child can become non-compliant.
Welch notes that things can go awry when mother and infant are separated too much. Such dysregulation in the dyad can lead to illness is one or both. It is especially visible in dyads with premature infants:
“Abnormal conditions, such as the repeated emotional and/or physical separation between mother and prematurely born infant, remove opportunity for optimal coregulatory conditioning and can lead instead to adverse co-conditioning. In such cases, dysregulation of autonomic state in mother, infant, or both, can trigger an autonomic reflexive withdrawal response upon close contact” (Welch, 2016, p. 1270).
Welch developed a technique, Family Nurture Intervention (FNI), that helps disconnected dyads reconnect through a co-conditioning process where repeated calming restores a positive visceral/autonomic co-regulation. The dyad begins with dysregulation and distress. They are cued to mutually share the distress with physical touch and with the mother expressing her emotional feelings. The mother cries and the child responds with soothing behaviors toward the mother while increasing self-regulation. Mutual upset begins to calm down. Multiple senses are involved from vision to touch to hearing to smell. Increased mutual calmness allows shared eye contact, singing or quiet talk or dozing. The process can take 4-6 sessions for these results.
These findings are important for ethics and moral development. Converging evidence suggests that empathic concern, central to compassionate morality, occurs bottom up from neurobiological resonance with the other that leads to feeling for or caring about the other. Observed in 8-month-old children, this is not dependent on self-reflection, mentalizing, or age, as is true for cognitive empathy and prosocial behavior, both of which typically increase across development (Davidov et al., 2013).

Explained by Darcia Narvaez and Mary Tarsha
With the pandemic and white-collar employees working from home, there are increasing calls for government-funding of child care to support parents in the workforce, especially mothers, who are falling behind their male colleagues in career advancement because they can’t get their expected work done when supervising children 24/7.
Of course, working mothers are not new outside of the middle class, who historically often had family members caring for young ones. And of course, it would be better to have extensive paid parental leave. The USA is the only one among 41 nations with no paid parental leave.
With mothers expecting and expected to work outside the home, the need for child care has never been so widespread. But the calls for child care often skip over discussing the exact nature of the care provided. What does quality care look like for young children? It’s about more than staff numbers or schedules. Much more is needed to prevent early life stress.
Early Life Stress
Communities are coming to realize that children should not be exposed to early life stress because it can have long term effects on health and wellbeing. For example, adverse childhood experiences (ACEs; Felitti & Anda, 2005) are often documented as family adversities like divorce and addiction, as well as personal adversity within the family like physical, sexual, or emotional abuse. Avoiding the harms of ACEs is important, but more is needed for babies and young children.
There are other stressors that babies and young children can experience that are also adverse. Early life stress is toxic—fostering short and long term problems—so one must understand how to prevent distress to young children.
Without an understanding of young child development and their basic needs, particularly baby development and needs, lots of harm can be done to children that can undermine health and wellbeing for the long term.
The Needs of Babies (0-2.5 years)
Babies are highly immature at birth with only 25% of adult brain volume at full-term birth and resemble fetuses of other animals until 18 months of age (Trevathan, 2009). This means that much of their biological, psychological and social capacities are grown after birth when the brain is rapidly developing in the first few years of life. https://www.zerotothree.org/ Many physiological systems are shaped by the quality of care received during early sensitive periods, such as the stress response (Lupien et al, 2009).
What kind of care do babies need as a result of their high immaturity? Exterogestation, that is, ‘a womb with a view’ (Montagu, 1970). It means that the baby’s needs are met immediately, just as in the womb, so that they can go back to growing rapidly (early on, mostly while sleeping).
Babies are especially vulnerable to unresponsive care. A sensitive caregiver adapts to the needs of the baby, providing comfort, calming and reassurance quickly whenever needed. In this way, the caregiving can be described as not perfect, but as “good enough.” Clinicians have described what this looks like among mothers:
“Good enough” means that mothers start off with “a high degree of adaptation to the baby’s needs…[a] tremendous capacity that mothers ordinarily have to give themselves over to identification with the baby. Towards the end of a pregnancy and at the beginning of a child’s life, they are so identified with the baby that they really practically know what the baby is feeling like, and so they can adapt themselves to the needs of the baby in such a way that the baby’s needs are met.” (Winnicott, 1990, pp. 144-145)
With a quick response to needs, which is not spoiling the baby, the caregiver keeps baby growing in a healthy manner (Schanberg, 1995).
From a psychological perspective, what babies routinely practice, they become. If they routinely interact joyfully with a responsive caregiver, those systems will become enhanced neurobiologically—they learn to be joyous. If babies are left in distress, various physiological systems can misdevelop, leaving the child dysregulated, stress reactive and/or self-focused (Lanius, Vermetten & Pain, 2010).
Center Care for Young Children (0-6)
Caregivers of young children should understand that they are shaping a child’s immune system, endocrine system (e.g., oxytocin), stress response, brain development and personality (Narvaez, 2014). As much as possible, child care workers caring for babies should mimic a mother’s care.
What does a responsive care center environment look like for a young child? We have developed a checklist for care center features based on the evolved developmental niche or evolved nest (Narvaez, 2014). Converging evidence across the sciences are demonstrating the importance of each of these factors for optimizing normal development and avoiding early toxic stress.
• Responsive, companionship care keeps baby optimally aroused to enable rapid neuronal growth. Baby’s needs are met immediately, as an “external womb.” This physical, social and emotional support system from friend-like familiar others keeps the child feeling connected and confident, building secure attachment.
• Affectionate touch (holding, carrying, rocking) which in our ancestral context, is nearly constant in the first years of life as physiological systems are setting their parameters of how well they will function, the psyche is figuring out its nature and place in the world. No negative touch—rough handling, pinching, slapping spanking, etc.—as this throws off the child’s optimal developmental pathway. Positive touch optimizes multiple systems like the stress response, the oxytonergic system, and the vagus nerve—which innervates all major body organs. Corporal punishment derails the development of self-regulation and social skills. Practices of routinely leaving babies alone in playpens, cribs, carriers instead of in arms have effects on growth and systems reliant on touch.
• A positive social climate where the child feels welcomed and like they belong to a community. Isolation and loneliness plague many people in the USA where babies are often sent to day care centers with rotating strangers, which harms their social development. A positive climate respects the dignity of the child (see Respecting Babies and Young Children
• Self-directed free play with playmates of different ages builds executive functions (e.g., redirecting actions and plans, empathy and control of aggression) and leadership skills. Children who do not experience whole-body play may be restless and unfocused, which adults may interpret as a need for pharmaceuticals.
• Nature immersion and ecological attachment so that the child builds biophilia–feels like a member of the earth community with responsibilities to non-human members. Societies that emphasize these practices foster nature’s biological diversity.
Partnership societies historically, typically matrifocal, focus on meeting the basic needs of their members, especially the young (Eisler & Fry, 2019). Such societies are not coercive but allow each individual to find their way and their gifts with supportive care, role models and stories, expecting self-determination in such a milieu to foster a virtuous character (Lavell-Harvard & Anderson, 2014).
The care a young child receives is critical for the type of trajectory they take—towards optimal wellbeing or not, towards long term resilience, or not. Early childhood care centers should be central to cultivating children’s wellbeing.

Community practices refer to everything outside a particular family, so that means policies and practices of neighborhoods, counties, cities, states, schools, and workplaces. Institutions that govern our lives also need to be responsible to promote flourishing in children. Here are some ideas for ways for community practices to support children and families.
