Co-regulation in toddlers helps manage emotions
Every parent knows it. A child melts down in the middle of a shop because they got a blue cup instead of a red one. Or bursts into tears because a biscuit broke. From an adult's perspective, it's a complete trifle; from the perspective of a two-year-old, it's a catastrophe of cosmic proportions. And in that moment comes the phrase that surfaces almost automatically: "Calm down." But that phrase doesn't work. It never has. And it's not the child's fault.
Over the past twenty years, developmental psychology and neuroscience have painted a clear picture of what is actually happening in a young child's brain. A toddler is not being defiant out of malice. A toddler is literally neurologically incapable of managing their emotions on their own. The prefrontal cortex — the part of the brain responsible for self-regulation, decision-making and impulse control — continues developing until early adulthood, approximately until the age of twenty-five. In a two-year-old, this region of the brain is only at the very beginning of its long maturation process. Telling a toddler to "calm down" is a bit like telling someone with a broken leg to stop limping.

What co-regulation actually means
Co-regulation is a process in which an adult — a parent, grandparent, or nursery teacher — actively helps a child navigate an emotional storm from the outside. In other words: the child borrows the adult's calming system, because they don't yet have one of their own. This is not spoiling. It is not capitulation. It is biology.
The concept of co-regulation draws on John Bowlby's attachment theory and the research of neurologist Allan Schore, who spent years studying how interpersonal relationships shape brain development in early childhood. Schore's work shows that a child's nervous system literally synchronises with the nervous system of the caregiver. When a parent is calm, present and regulated, they transmit this state to the child through voice, touch, facial expression and the rhythm of their breathing. This is not a metaphor. It is a physiological mechanism.
In practice, this means that when a toddler finds themselves in an emotional whirlwind, what they need above all is to feel that someone is with them who is not afraid of the storm. Someone who neither dismisses nor minimises it, but who also doesn't get swept away by it. Only from this secure foundation can the child gradually return to equilibrium. The goal is not to stop the storm quickly — the goal is to be present until it passes on its own.
Research published in the academic journal Child Development has repeatedly confirmed that children who experience consistent co-regulation from caregivers in early life gradually build their own capacity for self-regulation. In other words: the more help a child receives now, the less they will need later. Paradoxically, then, too much help is not the problem — the absence of it is.
Let us consider a concrete situation. Three-year-old Eliška has a meltdown every morning at breakfast. She doesn't want her milk in this cup, she wants it in a different one. She wants to pour her own juice, but she can't manage it yet, and then she cries over the puddle she's made. After several weeks of exhaustion, her mother Jana decided to change her approach. Instead of "stop crying, nothing happened," she started saying things like "I can see that really upsets you" or "come on, I'll sit with you." She didn't start relaxing all the rules. She didn't start granting Eliška's every whim. She simply stopped fighting the emotion itself and started being present alongside it. And within a few weeks, the morning rituals calmed down noticeably — not because Eliška had suddenly stopped having feelings, but because she had learned that feelings are safe and that they pass.
Practical phrases that actually help
The language parents use in difficult moments plays a crucial role. Phrases like "calm down," "stop crying," or "it's nothing" unwittingly communicate to the child that their emotions are wrong, excessive, or unwelcome. The child does not gain the skill to manage the emotion — they learn to suppress or hide it, which are two very different things.
Alternative phrases that support co-regulation operate on a different principle. They do not deny what the child is feeling, but give it shape, a name, and a safe framework. For example:
- "I can see you're very angry right now. I'm here with you."
- "That must have been a big disappointment. Come here, I'll hold you."
- "I understand that hurts. You don't have to manage this on your own."
- "You're allowed to be sad. I'll stay here until you feel better."
- "You know what, let's breathe through it together — me first, then you."
These phrases don't work miracles immediately. Their power lies in repetition and consistency. A child's brain learns through patterns. If a child repeatedly experiences that an emotional storm does not mean loneliness or punishment, but rather the presence and calm of an adult, they begin to form new neural pathways associated with a sense of safety. This is precisely what neuroplasticity in early childhood is about.
Just as important as words is the body. A voice lowered by a tone, slow breathing, physical proximity without forced hugging — these are all signals that the child's nervous system reads far more quickly than words. Sometimes it is enough to quietly sit down beside them on the floor and simply be there. Without commentary, without solutions, without judgement.
As child psychologist and bestselling author of The Whole-Brain Child Daniel J. Siegel puts it: "Connection always comes before correction." Only when a child feels seen and understood is their brain capable of receiving any guidance or explanation. If a parent attempts to explain rules in the middle of an emotional storm, they are quite literally speaking to the wrong part of the brain — the part that is, at that moment, offline.
Many parents worry that if they "give in" to a crying child or go to them, they will teach the child manipulation. This fear is understandable, but research does not support it. Co-regulation is not the same as the absence of boundaries. A parent can simultaneously be present with a child's emotion and still maintain a boundary. "I understand you want that sweet. I'm sorry you're sad that you can't have it. But you're not getting the sweet right now." Both at once. Empathy and boundaries are not opposites — they are allies.
Why the parent's own regulation is the first step
There is one crucial but often overlooked aspect of co-regulation: it only works when the adult themselves is regulated. If a parent approaches their crying toddler with tense shoulders, quickened breath and the feeling that "this is genuinely beyond me," their nervous system is not sending a signal of calm — it is sending a signal of threat. And the child will pick up on it instantly.
This does not mean parents must always be perfectly calm. That would be an unrealistic and unkind standard. What it does mean, however, is that caring for one's own regulation — whether that means taking a few conscious breaths before entering the room, allowing oneself a brief pause, or investing in longer-term mental health care — is not a luxury, but a foundation of parenting. As the saying goes on aeroplanes: put on your own oxygen mask first, then help others.
Parents who themselves grew up in environments where emotions were not named or were punished may find that co-regulation is challenging for them personally. This is not a failure. It is an invitation to their own growth. Many therapists and psychologists who specialise in parenting work with precisely this theme — helping adults reconnect with their own emotional world so that they can pass it on to their children in a healthy way.
The Czech Association for Psychotherapy or the portal Dobré místo can be a good starting point for parents seeking support in this area. This is not weakness — it is conscious parenting.
The toddler who today needs help coping with a broken biscuit will one day learn to handle disappointment at work, in relationships, in friendships. Neuroscience is clear on this: the foundations of emotional intelligence are laid in the first years of life, in precisely these seemingly small, everyday moments. In the moments when a parent says "I'm here" instead of "calm down." When instead of dismissal, they offer presence.
It is not always easy. It is not always possible to do it perfectly. But even imperfect co-regulation — the kind in which a parent sometimes fails, then comes back and tries again — is an enormous lesson for the child. It teaches them that relationships can be repaired. That emotions are not dangerous. And that they are not alone in the world.
