A nervous system overload may look sudden from the outside, but it's often preceded by more subtle changes — small signs that are information, not bad behaviour.

This infographic covers:

• A build-up, not always a sudden event — why early signs may not follow the same pattern every time, and why the goal is to notice change early
• Why early signs matter — how noticing early allows demands to be reduced and support offered before further escalation
• Common early signs of rising overwhelm across eight categories: changes in mood, changes in movement & behaviour, sensory changes, communication changes, body signals, changes in focus & processing, seeking safety & comfort, and changes in social engagement
• Closing reminder — don't wait for the biggest signal, look for the change
