Why kindness in nurseries shapes child development

---

TL;DR:

• Teaching kindness in nurseries improves children’s emotional regulation, social skills, and long-term well-being. Structured kindness education enhances academic performance, lowers stress, and fosters positive classroom dynamics, making it a valuable, low-cost focus. Consistent practice and reinforcement at home further strengthen these social-emotional skills for lifelong benefits.

Kindness in nurseries is defined as the deliberate practice of teaching children to recognise, express, and respond to the emotional needs of others within an early learning environment. The importance of kindness in nurseries extends well beyond good manners. Research from the Fondecyt Project and Coram PACEY confirms that structured kindness education improves emotional regulation, reduces biological stress, and builds the social foundations children carry into later life. A 2025 randomised controlled trial with children aged 4–5 found measurable gains in empathy, sharing, and conflict resolution alongside lower cortisol levels. These are not soft outcomes. They are predictors of long-term well-being.

What does research reveal about kindness programmes in nurseries?

The scientific case for teaching kindness in early childhood is grounded in neuroscience. Kindness is a fundamental human skill, comparable in developmental importance to literacy and numeracy. The early childhood years represent a critical window of neural plasticity, when repeated empathy practice physically builds prosocial circuits in the brain. This means kindness is not simply modelled and hoped for. It is trained.

The Fondecyt Project’s 2025 randomised controlled trial is among the most rigorous studies to date. It included 1,000 children and demonstrated that the intervention group showed better early maths performance alongside significant socio-emotional gains. That finding matters because it challenges the assumption that social-emotional learning competes with academic progress. The evidence shows the two reinforce each other.

Biological data strengthens the argument further. Structured kindness education lowers capillary cortisol in children aged 4–5. Lower cortisol means reduced chronic stress, which in turn supports better attention, memory, and learning readiness. This is a health outcome, not just a behavioural one.

Peer-led approaches also show strong results. Studies indicate that peer kindness programmes reduce bullying and victimisation significantly, with positive social behaviours increasing at a statistically meaningful level. While this research focused on children aged 8–10, the principles translate directly to nursery settings where peer relationships are first being formed.

Outcome	Evidence
Improved empathy	Demonstrated in Fondecyt Project 2025 RCT
Reduced biological stress	Lower capillary cortisol in children aged 4–5
Better early maths performance	Intervention group outperformed control group
Reduced bullying	Peer kindness programmes show statistically significant reduction
Improved classroom dynamics	8-hour staff training produced measurable positive shifts

Pro Tip: Ask your child’s nursery whether staff have received specific training in kindness-based pedagogy. Research shows that 8 hours of pedagogical training can produce significant positive shifts in nursery environments for children, educators, and parents alike.

Is kindness the same as good manners?

Kindness and manners are related but not the same thing. Manners are social conventions: saying “please” and “thank you,” waiting one’s turn, greeting adults politely. Kindness is an internal orientation. It requires a child to notice that another person is upset, feel something in response, and choose to act. That sequence involves emotional recognition, empathy, and decision-making. Manners do not.

This distinction matters in nursery settings because adults can inadvertently teach compliance rather than compassion. A child who says “sorry” on instruction has learned a script. A child who notices a friend is crying and offers a hug has practised genuine empathy. The goal of teaching empathy in nurseries is to develop the second response, not just the first.

Everyday kindness actions that nursery children can genuinely practise include:

• Noticing distress: Recognising when a peer looks sad or left out, without adult prompting
• Sharing resources: Offering a toy or art material without being asked
• Verbal encouragement: Saying “well done” or “I like your picture” to a classmate
• Physical comfort: Offering a pat on the back or sitting beside a child who is upset
• Inclusive play: Inviting a child who is alone to join a game

Manners complement these behaviours. A child who is both kind and well-mannered has the full social toolkit. The error is treating manners as a substitute for the deeper emotional work. Boundaries in toddler development and emotional regulation are closely linked to this process, as children who understand limits are better placed to practise empathy without becoming overwhelmed.

What kindness activities work best in nursery settings?

Effective kindness activities for preschoolers share three characteristics: they are concrete, repeatable, and socially visible. Abstract discussions about “being nice” do not register for children aged 3–5. Specific, structured activities do.

The most widely adopted approaches in nursery settings include:

1. Kindness cards: Children create simple illustrated cards for a peer, family member, or community helper. Making kindness cards and similar activities create meaningful social connections and have been used successfully during events such as Random Acts of Kindness Week.
2. Circle time discussions: A daily or weekly group session where children share one kind act they witnessed or performed. This builds reflective practice and reinforces that kindness is noticed and valued.
3. Storytelling and role play: Books and guided scenarios where characters face social dilemmas. Arts-based philosophical interventions foster introspection, self-awareness, and empathy by allowing children to engage emotionally with characters and situations.
4. Sharing projects: Collaborative tasks where children must divide resources, negotiate roles, or contribute to a group outcome. These build practical sharing skills in a structured context.
5. Peer support roles: Assigning a child the role of “helper” or “welcome friend” for a new or shy classmate. This gives kindness a social function and builds confidence in both children.

Parents play a direct role in reinforcing these activities. When a nursery uses kindness cards, parents who ask “who did you make your card for today?” at collection time signal that kindness matters at home too. That consistency between nursery and home is where the real developmental gains are consolidated.

Pro Tip: Replicate circle time at home with a simple question at dinner: “Tell me one kind thing you did today or saw someone else do.” This mirrors the reflective practices used in nursery settings and reinforces the habit of noticing kindness.

How does a kindness focus compare to traditional nursery priorities?

A common concern among parents is whether time spent on social-emotional learning takes away from early academic preparation. The evidence says it does not. The Fondecyt Project’s 2025 data showed that children in kindness programmes outperformed their peers in early maths. Emotional regulation and cognitive performance are not competing priorities. They are connected.

The table below compares outcomes across kindness-focused and traditional nursery approaches.

Priority	Kindness-Focused Approach	Traditional Academic Approach
Social skills	Explicitly taught through structured activities	Developed informally through play
Emotional regulation	Central to programme design	Addressed reactively
Cognitive development	Supported indirectly via reduced stress and improved attention	Primary focus
Resilience	Built through empathy practice and peer support	Variable
Staff well-being	Improved through kindness training	Not typically addressed
Resource cost	Low: 8 hours of staff training and low-cost materials	Variable

The resource efficiency point deserves attention. Kindness programmes require only modest investment: eight hours of staff training and low-cost materials such as recycled crafts and digital resources. The return on that investment includes improved child outcomes, better classroom dynamics, and measurable gains in educator well-being. Few educational interventions deliver across all three simultaneously.

The importance of social skills in childcare is also a school readiness issue. Children who enter Reception with strong empathy and conflict resolution skills adapt faster, form friendships more readily, and experience less anxiety. These are the foundations that well-trained childcare staff are best placed to build.

Key takeaways

Kindness in nurseries is a measurable developmental priority, not a supplementary activity, and the evidence from 2025–2026 research confirms it improves emotional, social, and cognitive outcomes simultaneously.

Why i believe kindness is the most underrated skill in early education

I have spent years observing nursery environments, and the pattern is consistent: the children who thrive socially at age five are rarely the ones who learned the most letters or numbers at three. They are the ones who learned how to read a room, respond to a friend in distress, and recover from a disagreement without adult intervention. Those are kindness skills. They are also life skills.

What strikes me most about the recent research from the Fondecyt Project is not the cortisol data, impressive as it is. It is the maths finding. The idea that teaching a child to be kind also makes them better at early mathematics should reframe how nurseries and parents think about the curriculum. Kindness is not the soft option. It is the foundation.

I also think parents underestimate their own role. Nurseries can do excellent work during the day, but a child who hears “what kind thing did you do today?” at home is receiving a consistent message that kindness is valued everywhere, not just at nursery. That message compounds over time. The arts in early childhood also offer a powerful route into this work, giving children a language for emotions before they have the words.

My honest view is that any nursery not actively and intentionally teaching kindness is leaving significant developmental potential on the table. The evidence is there. The tools are affordable. The results are measurable. There is no good reason to treat kindness as an afterthought.
