When behaviour is a signal

The vast majority of challenging behaviour in children is developmentally typical. Some of it is telling you something a child cannot yet say. These five patterns, when persistent, are worth a conversation with a GP or child psychologist.

1. The behaviour is out of proportion to the trigger — every time

A child who falls apart after a hard school day is typical. A child who falls apart after a minor change in plan — every time, for weeks, at an age where that should be easing — is telling you the regulatory system is not developing at pace. This is one of the more reliable early features of ADHD and autism, and of anxiety in younger children.

2. The behaviour is different at home than anywhere else

'Fine at school, explodes at home' is a common pattern. It can be a child who is holding themselves together all day using every spare resource, and coming home empty. Known as 'after-school restraint collapse', it is a normal experience for many neurotypical children occasionally — and a daily feature for many neurodivergent ones. Daily is the signal.

3. The behaviour started, or intensified, after something specific

A change in the family, a house move, a friendship fracture, a death, a new sibling, a pandemic — any of these can legitimately shift a child's behaviour. If the shift is sustained (more than four to six weeks), and the family circumstance is known, it is often worth involving a psychologist to help the child process the event rather than waiting it out.

4. The child is talking about themselves in the way you would never let a stranger talk to them

'I'm stupid.' 'I'm bad.' 'Nobody likes me.' 'I should just not be here.' This kind of self-talk, when it is recurring and not clearly situational, is a signal. The last one — any language around not being here, not wanting to be alive, wishing they could disappear — is always urgent. This is a Kids Helpline call and a same-week GP visit, not a parenting article question.

5. You, the parent, have been off-balance for weeks

Parental intuition is not magic, but it is a signal worth reading. If you have been worried, quietly and consistently, for longer than six weeks — not panicking, just unable to shake it — that is the time to book the appointment. You do not need to be certain. You need to be curious.

What happens after the signal

You take the signal to your GP. The GP will often refer to a paediatrician, psychologist, or both. In Australia, a GP Mental Health Care Plan (MBS item 2715) unlocks up to ten subsidised psychology sessions a year. You do not need a diagnosis to access support. You need the pattern and the GP appointment.
