Your child comes home from Pre-school, drops their bag at the door, and bursts into tears over something that seems impossibly small. To them, it is not small at all. For young children aged 18 months to six years, emotions arrive like sudden storms: fast, overwhelming, and without warning. Teaching children to manage these moments is not simply about preventing tantrums. It is about building one of the most important foundations a person can have for a healthy, successful life.
Emotional regulation, the ability to recognise, understand, and manage feelings in appropriate ways, is a skill that takes years of consistent, patient support to develop. Research confirms that children who build strong emotional regulation skills in their early years go on to achieve better academic outcomes, form healthier relationships, and cope more adaptively with life’s challenges. The good news for parents and educators is that there are clear, evidence-based ways to help young children build these skills, starting right now.
This guide walks through the neuroscience behind big feelings, the developmental stages of emotional regulation, and a set of practical strategies that work both at home and in the Pre-school classroom. You will also find out how ChildFirst’s Human Intelligence curriculum weaves emotional development into every school day, because social and emotional competence is every bit as essential as academic readiness.

Why Big Feelings Feel So Big: The Brain Behind the Meltdown
When a four-year-old dissolves into a full meltdown because their sandwich was cut into squares instead of triangles, it can feel bewildering. The explanation, however, lies squarely in neuroscience. The prefrontal cortex, the part of the brain responsible for impulse control, planning, and emotional regulation, is also the last region of the brain to mature. It continues developing well into the mid-twenties. Meanwhile, the amygdala, which drives fast, reactive emotional responses, is comparatively active from early infancy. The result is a young child whose emotional accelerator is in full working order long before their brakes are installed.

Prefrontal Cortex
Responsible for impulse control, planning, and emotional regulation. The last region of the brain to mature, continuing to develop well into the mid-twenties.
During the Pre-school years, specifically from ages three to six, the frontal lobes undergo rapid growth. A child’s brain reaches approximately 90% of its adult size by age six, yet the prefrontal cortex’s regulatory functions remain limited throughout this window. This means that impulse control, perspective-taking, and the ability to pause before reacting are genuinely difficult for young children, not a sign of poor parenting or poor behaviour. Understanding this is the first gift a carer can give themselves when navigating a challenging moment.
Importantly, this period of rapid brain development is also a window of significant opportunity. Early experiences, especially responsive and nurturing caregiving, actively promote the growth of neural circuits that support emotional expression and regulation. Research shows that nurturing and responsive caregiving enhances the development of brain circuits linked to emotional control. Every calm response to a child’s distress, every name given to a feeling, and every patient moment of guidance is, quite literally, building the brain.
