Understanding triggers

How to spot patterns and reduce sensory, social and demand-based triggers.

6 min read

Spotting what tips your child past coping

Behaviour that looks "sudden" usually isn't. There is almost always a build-up of unmet needs, stress, sensory input or anxiety before a meltdown, shutdown or refusal.

Common categories of trigger

  • Sensory: noise, lights, smells, clothing, crowds, lunch halls, fire alarms.
  • Demand: being told what to do, multi-step instructions, unexpected requests.
  • Transition: moving from a preferred to a non-preferred activity, end of holidays, new term, new teacher.
  • Social: group work, eye contact, conflict, friendship problems, being watched.
  • Internal: hunger, tiredness, pain, hormones, illness, needing the toilet.
  • Emotional: anxiety, fear of failure, embarrassment, shame, loss of control.

Keep a simple log

For a couple of weeks, note:

  • What happened
  • Where and when
  • Who was there
  • What had happened in the hour before
  • What seemed to help
  • What made it worse

Patterns often appear quickly — same time of day, same lesson, same trigger.

Share it with school

A clear list of triggers and supports is more useful to staff than a label. It tells them what to watch for and what to change.

Key message

Triggers are information, not excuses. Once you know them, you can plan around them.
