# Can you tell if a 6–9-month-old has ADHD? Canonical: https://pinnacleblooms.org/ask/adhd-infant-6-9-months-when-to-worry Publisher: Pinnacle Blooms Network / Bharath Healthcare Laboratories Private Limited At six to nine months, ADHD cannot be diagnosed — a baby's attention and activity are still developing normally. Clinicians don't evaluate for ADHD before about age 4. Track general milestones instead, and have any genuine developmental delay checked early. *Take a breath — at six to nine months, there is no such thing as a diagnosable case of ADHD, and a wriggly, distractible baby is almost always just a baby.* ## In short ADHD cannot be identified in infancy. A baby's attention span, impulse control and activity level are still forming, so the behaviours that define ADHD simply don't apply yet. Clinicians do not evaluate for ADHD until at least age 4, when behaviour can be compared meaningfully to peers across home and other settings. What you *can* do now is track general development — and if anything feels off, have it checked. ## What is actually age-appropriate at 6–9 months At this stage, healthy babies are *meant* to be highly active and unable to sustain attention — that is normal neurological development, not a warning sign. Instead of watching for "ADHD", watch the broad milestones: 1. **Social** — sharing smiles, seeking your face, beginning to respond to her name. 2. **Communication** — babbling, taking turns with sounds, responding to your voice. 3. **Motor** — sitting, reaching, transferring objects hand to hand. 4. **Hearing and vision** — startling to sound, tracking objects and faces. A delay in *these* is far more meaningful at this age than any worry about attention. ## The Pinnacle way We don't put an infant through an attention "test". We look at the whole child across every developmental domain and, where useful, a clinician at a [Pinnacle Blooms Network centre](/find-center) uses the [AbilityScore®](/ask/what-is-the-abilityscore-and-how-is-it-calculated) to map strengths and gaps and decide whether anything needs support. If attention concerns are still present closer to preschool age, that is the right moment to look harder — see our guide to [ADHD](/adhd). This is general information, not a diagnosis — individual assessment and diagnosis require an appropriately qualified healthcare professional. ## Trusted sources The WHO ICD-11 framework classifies ADHD (6A05) as a disorder identified in childhood, not infancy; the AAP's developmental-milestone guidance is the right yardstick for a baby this age. **Next step —** if any milestone feels behind, book a free developmental check; if not, simply keep tracking.
