Empathy is often discussed as though it either exists or it doesn't — a fixed trait that some children are born with and others aren't. The developmental picture is more interesting than that. Empathic capacity begins in the first weeks of life, unfolds in observable stages through toddlerhood and early childhood, and is substantially shaped by what happens around the child.
This matters practically: what parents do with very young children influences the development of a capacity that underpins friendships, moral reasoning, and almost everything that makes someone a good person to know.
Healthbooq (healthbooq.com) covers social and emotional development across the early years, including how prosocial behaviours develop and how parents can support them through everyday interactions.
The Earliest Foundations
Empathy in its most basic form is the capacity to share in and respond to another's emotional state. The earliest precursor appears in the first days of life: newborns cry in response to the cries of other newborns, and this response is not simply a reaction to noise — studies have shown they cry less intensely in response to synthetic crying of equal volume. Something about the sound of another infant's distress specifically activates a response.
By around 6 to 9 months, infants show social referencing: they look to a caregiver's face to read their emotional reaction to a novel object or event, then regulate their own response accordingly. If the parent looks alarmed, the infant pulls back. If the parent smiles and nods, the infant explores. This is the beginning of reading another person's internal state to inform one's own behaviour.
Joint attention, which develops around 9 to 12 months, involves sharing focus on an object or event with another person — the infant looks at a bird, then at you, then back at the bird, checking that you're seeing what they're seeing. This reflects an emerging understanding that other people have experiences and interests separate from one's own, which is a foundational component of empathy.
Toddler Prosocial Behaviour
The most striking evidence that empathy begins early comes from research by Felix Warneken and Michael Tomasello at the Max Planck Institute for Evolutionary Anthropology. In a series of experiments, they found that infants as young as 14 to 18 months spontaneously helped adults who were clearly struggling with simple tasks — without being asked and without any reward. A 16-month-old would pick up an object an adult had dropped and appeared to need, or open a cabinet door for an adult whose hands were full. The helping appeared to be driven by genuine understanding of the adult's goal rather than by learned compliance.
Around the same age, toddlers begin showing concern for distressed others. Seeing another child cry, or watching an adult who appears upset, toddlers frequently approach with comfort objects, with patting, or with sounds of concern. This is empathic concern, not imitation.
Between 18 months and three years, children begin sharing and offering objects to others. Sharing in competitive situations — where it requires giving up something desirable — develops more gradually than sharing in cooperative or familiar situations. A two-year-old who shares a toy with their best friend at nursery may not be ready to share the same toy with a stranger at the park. This is not inconsistency or manipulation; it's the normal developmental progression.
Theory of Mind and Cognitive Empathy
The richer form of empathy — the ability to model another person's beliefs, desires, and perspective accurately, even when they differ from your own — depends on theory of mind, which develops primarily between three and five years.
The classic test of theory of mind is the false belief task: understanding that another person can hold a belief that is factually incorrect because they have different information from you. In the standard version, a child watches a character hide an object, then the character leaves and someone moves the object. Where will the character look when they return? Most children under three and a half answer "where the object actually is." Most children over four and a half answer "where the character put it" — correctly modelling the character's (now false) belief. The shift happens because the child's prefrontal cortex has developed enough to hold two conflicting representations simultaneously.
Theory of mind opens up the more sophisticated forms of empathy: understanding that someone might feel sad about something you'd find trivial, imagining how a situation looks from another vantage point, recognising that the same event can affect different people in different ways.
How Parents Support Empathy Development
The most reliable predictor of empathy development is how a child's own emotions are responded to. Children whose emotional experiences are acknowledged, named, and taken seriously develop better understanding of their own inner states — which is the foundation for understanding others' inner states. This is the inside-out mechanism: empathy for others grows from self-awareness.
Talking about others' feelings in concrete, specific terms gives children the framework for thinking about mental states. "Look at that little girl — she looks sad because the dog ran away" is more useful than "be kind." "Your brother's crying because he bumped his knee really hard" teaches causal reasoning about emotions. "Grandma looked so happy when you showed her your drawing — how do you think she was feeling?" invites the child to practise perspective-taking.
Reading picture books with emotionally complex characters and asking open questions about how characters feel, and why, gives children regular low-stakes practice at perspective-taking. Books where the illustrations carry emotional information — a character's expression, posture, the tone of a scene — allow even pre-verbal children to participate in conversations about feelings.
Modelling empathy matters directly. Children observe how adults respond to others' distress, how they talk about people who are struggling, how they handle conflict. These observations shape the template for empathic behaviour more than instruction does.
What is not effective: demanding that a two-year-old share before they have the developmental capacity for generosity, or treating the normal self-centredness of a young toddler as a moral failing requiring correction. Empathy is built through experience of having one's own emotions understood, not through pressure to display emotions one doesn't yet have the architecture to feel.
Key Takeaways
Empathy begins developing from infancy and emerges in early prosocial behaviours in the toddler years, long before children develop the full theory of mind capacities needed for mature perspective-taking. Infants as young as 14 to 18 months spontaneously help adults with simple tasks and show concern for distressed others. Empathy is shaped by experience, particularly by how children's own emotions are responded to and whether they are helped to think about others' inner states. It is not purely innate and can be meaningfully nurtured.
