Worry is a reason to observe and seek a general developmental check, not to label. Only a clinician can tell the difference.","answer_md":"*If your three-year-old never seems to sit still, the worry is real — but at this age, that liveliness is usually childhood, not a diagnosis.*\n\n## In short\nAt three, being constantly on the go, having a short attention span, and acting before thinking are completely typical — preschoolers are *meant* to be busy. [ADHD](/adhd) (ICD-11 **6A05**) is rarely diagnosed reliably this young, because the behaviours that define it overlap so much with normal toddler development. The honest answer: worry is a reason to *observe and check*, not to label. A clear pattern — far beyond same-age peers, across home and playgroup, and lasting many months — is what warrants a developmental review.\n\n## What to watch (rather than worry over)\nAt three, gently note whether behaviour is **out of step with other children the same age** and persists across settings:\n\n- Activity so constant it stops *any* play from settling, even briefly\n- Attention shorter than peers for things the child enjoys\n- Impulsivity that repeatedly risks safety despite reminders\n- Difficulty that shows up **both** at home **and** at crèche or with relatives\n\nBehaviour seen in only one place, or that eases with routine and sleep, usually points to environment, not ADHD.\n\n## The science, briefly\nLeading guidance (NICE NG87, the AAP and CDC) is cautious about diagnosing ADHD before school age, because attention and self-control are still rapidly maturing at three. When concern is genuine, the first step is a **general developmental check** — to rule out hearing, sleep, language or anxiety factors that can look similar. Where preschool support is offered, it begins with parent-focused [behaviour therapy](/behaviour-therapy), never medication first.\n\n## The Pinnacle way\nNo diagnosis is ever made from an online form — Developmental measurement supports care planning; diagnosis requires an appropriately qualified healthcare professional., under a qualified clinician's care. Our clinicians measure your child against their *own* [developmental baseline](/ask/what-is-the-abilityscore-and-how-is-it-calculated), look for everyday causes first, and give you clarity and a plan — not a hasty label.\n\n## Trusted sources\nWHO ICD-11 (6A05); CDC Learn the Signs, Act Early; American Academy of Pediatrics (HealthyChildren.org); NICE NG87 on ADHD; Indian Academy of Pediatrics.\n\n**Next step —** The kindest thing to do with worry is to check.
