Why does my child have no sense of time?

The short answer

Time blindness is an informal term for difficulty noticing, estimating or acting on time. Research has found that children and adolescents with ADHD are less accurate and less consistent on timing tasks on average, but the findings vary and do not diagnose an individual child. Everyday lateness can also involve attention, working memory, task switching, planning or an unclear routine. Make time visible and actionable: show what happens before the deadline, use a countdown that the child can see, compare estimates with actual duration, and give transition cues tied to a concrete stopping point.

• Time blindness is a popular description, not a diagnostic criterion.
• Timing studies show group differences, not an absence of time sense in every child with ADHD.
• Knowing a clock time is different from using it to organise several actions.
• Countdowns, elapsed-time displays and event-based cues serve different purposes.
• Calibrate estimates without shame by comparing predicted and actual duration.
• A time aid should be visible where the decision happens and easy to reset.
