You need to document your child's behaviours for professionals
Notebook or tracking app, a folder or binder, school communication
Professionals see a snapshot of your child. An evidence file provides the full picture — patterns across weeks and months that a single appointment can't capture. It shifts the dynamic from 'parent's concerns' to documented, observable data.
Start gathering evidence as soon as you have concerns, at any age. Even 2-3 weeks of observations can be enormously helpful.
One parent kept a simple notes app on their phone and jotted down observations throughout the day. By the time the assessment appointment came, they had six weeks of data that the clinician described as 'the most useful parent evidence I've ever received.'
