Early signs of ADHD in a 6-to-9-month-old
ADHD cannot be identified in a 6-to-9-month-old — there is no infant ADHD signs list, and busy, distractible baby behaviour is normal. ADHD is usually considered only from around 4–5 years, when attention and activity can be compared with peers. For now, simply track general milestones and book a routine developmental check if anything worries you.

When a baby is wriggly, restless or hard to settle, it's natural to wonder — could this be ADHD? Here's the honest, reassuring answer.
In short
ADHD cannot be identified in a 6-to-9-month-old, and there is no list of infant ADHD signs to watch for. ADHD (ICD-11 6A05) involves sustained patterns of inattention, hyperactivity and impulsivity judged against what's expected for a child's age — and these simply cannot be reliably told apart from completely normal baby behaviour this early. So please breathe: a busy, active, easily-distracted baby is usually just being a baby.
What is appropriate to watch at 6–9 months
Rather than hunting for ADHD, this is a wonderful window to enjoy and gently track your baby's general development:
- Social warmth — smiling back, enjoying peek-a-boo, turning to your voice
- Babbling — strings of sounds like "ba-ba", "da-da"
- Looking and reaching — following objects, reaching for toys, passing them hand to hand
- Sitting and rolling — building steadiness and trunk control
- Responding to name and showing interest in faces
Wriggling, short attention to a single toy, and getting bored quickly are all entirely typical at this age — not early ADHD.
When ADHD assessment becomes meaningful
ADHD is usually considered from around 4–5 years and older, when a child's attention, activity and impulse control can be fairly compared with peers across home and preschool. If, as your child grows, you ever notice attention or activity that is clearly out of step with other children the same age, that is the time to raise it — not now.

CONNECT THE ANSWER TO YOUR CHILD’S DAY
Something to notice. Something to discuss.
What to notice
Not ADHD signs — instead watch general 6–9 month milestones: smiling and social warmth, babbling, reaching and passing toys, sitting steadily, and responding to name. Raise any milestone concern at a routine developmental check rather than worrying about ADHD this early.
In everyday life
Spend a few minutes daily in face-to-face play — talking, babbling back, peek-a-boo. This nurtures attention and connection naturally, and helps you notice your baby's developing skills.
Bring your observations and questions to your child’s professional. Choose activities that suit your child’s comfort, abilities and agreed plan.
Bring your questions to a first visitQuestions families ask
Can ADHD be diagnosed in a baby?
No. ADHD cannot be reliably identified in infancy, as it involves patterns of attention, activity and impulse control judged against peers — something only meaningful from around 4–5 years and older.
My 8-month-old is very active and restless. Is that ADHD?
Almost certainly not. High activity, short attention to one toy and quick boredom are all typical baby behaviours at this age and are not early signs of ADHD.
When should I actually start thinking about ADHD?
Usually from around 4–5 years, if attention or activity is clearly out of step with other children of the same age across home and preschool. Raise it with your paediatrician at that point.
What should I focus on now instead?
Enjoy and gently track general milestones — social smiling, babbling, reaching, sitting and responding to name — and attend routine developmental checks.
