Why your child's emotions sometimes seem so overwhelming
An 18-month-old collapsing in tears because their toast was cut into a triangle instead of a rectangle. A 9-month-old screaming the second you leave the room. A 2-and-a-half-year-old toddler caught in a fit of rage they don't even know how to get out of. These everyday scenes are not a sign of a difficult personality or a lack of upbringing. They are, in the most literal sense of the term, neurologically normal.
Understanding what is happening in your child's brain between 0 and 3 years old radically transforms how you can support them. Not to eliminate emotions, but to learn how to respond to them in a way that gradually builds their capacity for self-regulation.
A young child's emotional brain: what science tells us
The human brain develops from the bottom up and from the inside out. The brainstem, responsible for vital functions, is already mature at birth. The limbic system, the seat of emotions, is active and functional from the first weeks of life. However, the prefrontal cortex, which allows for emotional regulation, perspective-taking, impulse control, and logical thinking, will not reach full maturity until around 25 years of age.
This asymmetry is fundamental: your child feels intense, real, overwhelming emotions, but they do not yet have the neurological tools to manage them alone. Emotional regulation is not an innate skill. It is a skill that is learned, progressively, through relationships.
Co-regulation before self-regulation
Developmental neuroscience introduces a central concept: co-regulation. Before being able to regulate themselves, children regulate themselves through the calm and constant presence of their primary caregiver. When a parent acknowledges an emotion without denying it, without punishing it, without being afraid of it, they offer the child a neurological model. Over time, the child internalizes these experiences and builds their own capacity for regulation.
Daniel Siegel, a neuropsychiatrist and renowned author on conscious parenting, describes this process as 'naming to tame': putting words to the felt emotion activates the prefrontal cortex and reduces the intensity of limbic system activation. In other words, telling your child 'you're very angry because you still wanted to play' is not an empty phrase. It is a concrete neurological intervention.
From 0 to 3 years: understanding the stages of emotional development
The first few months: emotions as a language
From birth, infants express fundamental emotional states: distress, satisfaction, interest, disgust. They have no words, but their bodies speak. The quality of the parent's response to these signals, which John Bowlby theorized as attachment, directly shapes the architecture of the child's emotional brain. A baby whose needs are consistently heard and met develops a sense of internal security that will be their emotional foundation for life.
Between 6 and 18 months: the emergence of secondary emotions
Fear of strangers, separation anxiety, shared joy, frustration: these more complex emotions gradually emerge. The child begins to recognize the facial expressions of those around them and respond to them. The parent's gaze becomes a powerful regulator. In moments of uncertainty, the child 'consults' their adult's face to know if the situation is safe. This phenomenon, called social referencing, is active from 9 to 12 months.
Between 18 months and 3 years: the great emotional storms
This is the period of the famous 'tantrums'. The child gains a stronger self-awareness, has asserted desires, a nascent sense of autonomy, but the tools to manage frustration are still very limited. These crises are not manipulations. They are the expression of an overwhelmed brain. The parental response at these times is crucial: it can either amplify the state of agitation or help the child get out of it.
The Montessori approach: preparing a secure emotional environment
Maria Montessori not only designed physical spaces. She designed emotional spaces. In her philosophy, the adult is neither a judge nor a savior of the child's emotions: they are an attentive observer and a discreet regulator. Several concrete principles emerge from this for daily life.
Name without minimizing
Replacing 'it's nothing, stop crying' with 'I see you're very sad, I'm here' may seem trivial. In reality, this simple reformulation validates the child's inner experience, teaches them emotional vocabulary, and strengthens the bond of trust. Studies in developmental linguistics show that children whose parents regularly use rich emotional vocabulary develop better emotional intelligence from the age of 3.
Create rituals that provide security
Predictability is an antidote to anxiety. Daily routines, bedtime rituals, structured transition times reduce underlying stress levels and free up cognitive resources for exploring, learning, and playing. A child who knows what will happen can relax. A relaxed child regulates better. It's a virtuous cycle.

Allow room for free play
Undirected play is one of the privileged spaces where children learn to manage frustration, negotiate their desires with reality, and tolerate uncertainty. When a block doesn't fit into the designated hole, when a construction collapses, the child experiences frustration in a secure setting, at their own pace. Our article on free play and gadget-free creativity from 0 to 3 years old explores these mechanisms in detail.
The physical environment as emotional support
The space in which a child develops is not emotionally neutral. An environment adapted to their size, designed to promote autonomy, reduces sources of unnecessary frustration and supports nascent self-esteem. When a child can reach their belongings, explore freely, and move unhindered, they feel capable. And the feeling of competence is a powerful emotional regulator.
It is with this perspective that the Treelys play mat was designed: to offer a space for sensory and motor exploration on the floor, at child height, where the baby can experiment at their own pace, without constraint and without overstimulation. A safe and soft floor is also a space where emotions can flow freely.
What you can do concretely starting today
Supporting your child's emotional development does not require specialized training or particular equipment. It mainly requires presence, attention, and inner availability. Here are some simple points of support.
Welcome all emotions, even the difficult ones
Anger, fear, jealousy, sadness are normal human emotions. Suppressing them does not make them disappear: they seek other, often less accessible, avenues of expression. Welcoming an emotion does not mean accepting the behavior that accompanies it. You can say 'I understand you're angry' and 'I won't let you bite' at the same time.
Take care of your own regulation
A parent overwhelmed by their own emotions cannot co-regulate effectively. Taking a few seconds to step back, breathe, and place your hands is an act of parenting in itself. Your inner calm is the most precious resource you can offer your child in these moments.
Observe before intervening
Not all cries require the same response. Observing what the child needs, sometimes just to be seen, sometimes to be carried, sometimes to be guided, is a skill that refines over time. Language development also plays a key role in this ability to express inner states. Our article on language development and a baby's first words explores this link in depth.
An intelligence that is built over time
Emotional intelligence is not a fixed character trait. It is an architecture that is built slowly, in relationships and repeated experience. Each time a child experiences a difficult emotion with the support of a stable adult, a new neural connection is strengthened. Each time they put a word to what they feel, their brain learns to better navigate this inner ocean.
You don't need to be perfect in this support. Researchers speak of a 'good synchronization' rate with your child of around 30% for secure attachment to form. What matters is regularity, sincerity, and repair when the connection is broken. It is in these cycles of rupture and reconnection that your child's emotional resilience is forged.
