Sensory sensitivity:
reduce, choose, escape

What it looks like

Many children show some of these. The question is how much it limits the child's day.

It is real discomfort

Sensory sensitivity is a characteristic of how a child's nervous system processes input, not a habit and not a choice. The child who screams at the hand dryer is not being difficult; they are in distress. This matters for what you do next: you do not "get them used to it" by force, because that teaches the child that the place is unsafe and the adult will not help.

Three strategies

• Reduce — take the edge off the trigger in advance: ear defenders for fireworks, tags cut out, a plan to use the toilet before the hand dryer is needed, a quieter corner of the café.
• Choose — offer a way to take part that fits: a paintbrush instead of fingers, watching first and joining later, a seat at the edge.
• Escape — agree in advance where the child can go to recover, and a way to say "too much" (a word, a sign, a card). An exit that is allowed prevents the exit that is a meltdown.

Over time, with the pressure off, many children's tolerance widens on its own. The goal is not to make the sensitivity disappear; it is to grow the child's ways of coping with it.

Talking to the daycare

Tell the staff specifically what your child is sensitive to and what helps, in writing if your Japanese is limited — a short list is enough. Daycares in Japan are used to making reasonable adjustments (合理的配慮) and most will do so gladly once they understand. If the group setting is where most of the difficulty shows, ask us about visiting support, where our specialists go to the daycare and work out the adjustments with the staff there.

Common misunderstandings

• "They'll get used to it if we keep exposing them." Forced exposure tends to make things worse. Building ways of coping works better than building tolerance by force.
• "Ear defenders will make their hearing more sensitive." There is no evidence for this. Used for the loud moments, they are a tool, not a crutch.
• "It's just fussiness." Fussiness does not usually come with distress, avoidance and recovery time. Sensitivity does.

When to seek help

Talk to someone when the sensitivity is limiting daily life — meals, dressing, going out, daycare — or when it comes with language or group-life difficulties. An occupational therapist or a classroom with a sensory-aware team can assess what is going on and build the three strategies into a plan. No diagnosis is needed to ask. Your ward's child development support centre and public health centre are the public starting points; we are one of the classrooms.
