Why is my child so sensitive?

The challenges of parenting a highly sensitive child
By Genevieve Simperingham

Do you have a child who seems to feel everything so deeply? One moment they’re glowing with happiness, noticing the smallest details of beauty in the world. Next, they’re melting down over what seems like a minor noise, a sudden change of plans, or the texture of their t-shirt. If you can relate to this, know that you’re not alone.

These parents tend to genuinely love and appreciate their child’s beautiful sensitivity, including the ways they tend to notice that which others don’t. Yet those same parents can feel utterly exhausted by the daily challenges of helping their child navigate a world that often feels too loud, too bright, too fast-paced, too much!

High sensitivity isn’t a flaw, and the answer isn’t to “toughen them up”. These children also tend to bring incredible gifts like deep compassion, creativity, curiosity and intuition. So be assured that there are contributing factors and things we can do as parents that help or hinder your child’s ability to, not just cope with their high sensitivity, but to truly flourish. But before we get into that;

“Why is my child so highly sensitive?”

Perhaps surprisingly, at least 20% of children are born with a more perceptive nervous system. More broadly, around 40% of children, if diagnosed, would present with one or more conditions associated with higher sensitivity, including anxiety, neurodivergence, or sensory processing challenges. Children with ASD will very often also experience sensory integration difficulties, high sensitivity, and as a result, significant anxiety.

Strong-willed or alpha children also tend to be highly sensitive. High sensitivity is also common in children who have experienced disrupted attachment or unresolved trauma. Regardless of the underlying cause, the common thread is an overactive nervous system, a lower stress tolerance, and a child who is more easily overwhelmed and harder to soothe.

The Real Challenges You Face as Their Parent

Because highly sensitive children can become easily stressed or overwhelmed by external stimuli, they can feel very out of control. Because they have an overly sensitive nervous system and low stress tolerance, they often interpret a situation as a threat, where another child isn’t fazed. When they feel out of control, these children can attempt to regain control by becoming very resistant, perhaps demanding and generally being very particular and controlling. 

Parents of highly sensitive children often feel like they’re walking a tightrope. They might sigh in relief as they watch their child light up in a quiet moment of connection. Then see them explode or shut down in a crowded supermarket, a birthday party, or the morning rush to school. 

Sensory overload can come from loud noises, bright lights, strong smells, rough textures, strong emotions (positive or negative), someone’s tone of voice, or expressive body language.. Their vulnerable nervous system takes it all in deeply and can quickly reach capacity. For all these reasons and more, these children can struggle with groups, being in public and changes to the routine. 

Transitions can be another huge trigger

Moving from playtime to dinner, or home to school, or a new person entering the house can feel like an enormous shift. Expectations, even gentle ones, can spark resistance or tears because their system is already running on high alert. You might find yourself managing more meltdowns, clinginess, or withdrawal than other parents seem to deal with.

On top of managing your child’s sensitivities, there’s often the external pressure of well-meaning comments from family or strangers suggesting you’re “spoiling” them or that firmer parenting would fix things. Perhaps you’ve found yourself diplomatically advocating for your child’s needs with other adults, hoping to elicit their compassion, and to protect your child from harsh judgments.

The emotional holding can be immense. Constantly scanning for triggers, holding space for big feelings, while trying not to lose the plot yourself can be exhausting. And completely understandable. Especially if you were that highly sensitive child yourself, growing up feeling pressured and misunderstood.

Peacefully parenting your highly-sensitive child

At the heart of it, your child’s “difficult” behaviour is usually a signal that their nervous system is overwhelmed and dysregulated. When that behaviour gets labelled as defiance or manipulation, it creates disconnection. Your child senses the judgement and craves your compassion, which amplifies their stress. What they desperately need in that moment is a warm connection, to feel seen and safe again.

Parents feel more empowered when they understand that the reactive, controlling behaviours are signals not character flaws. Everything changes when parents realise that their child’s nervous system is overloaded, and that they’re crying out for co-regulation and emotional safety.

Their child’s highly attuned nervous system picks up subtleties others miss, so even small stimuli can build up like a pressure cooker. A backlog of unresolved feelings from a busy day, a disappointment, or just the general stimulation of being alive, makes them more reactive. What looks like a tantrum over “nothing” is often their system screaming, I can’t process any more right now. This is what Aletha Solter called the “broken cookie syndrome”: the cookie breaking is simply the last straw that opens a dam of unexpressed feeling.

When we push through their sensitivities with dismissive comments like “just get in the car!” or “it’s not a big deal,” we add to their stress and erode their sense of emotional safety. Instead, our role is to be their safe base, their co-regulator. When we read their fussiness or reactivity as a signal that they need our help, we have a chance to take a breath, steady ourselves, and offer them our calm, steady presence. This isn’t permissive parenting; it’s responsive, attachment-based parenting that meets them where they are.

Over time, feeling truly understood actually builds their capacity to handle more, not less. The child who learns to slow down, feel their feelings, and express them to a safe person will develop not just emotional resilience, but the beautiful ability to hold space for others and to recognise when doing so is too much for them.

As Carol Stock Kranowitz describes it so vividly in The Out-of-Sync Child: the overresponsive nervous system essentially says, “Whatever that is, it is way too much, you’re flooding me. I can’t bear the touch of it, the smell of it, the look of it. Let me live under the table or with the covers over my head and never let me get out of bed.” If this article resonates with you, I highly recommend her book and accompanying workbook as practical resources for any parent of a highly sensitive child.
