# What are the early signs of ADHD in a 3-to-6-month-old? Canonical: https://pinnacleblooms.org/ask/what-are-the-early-signs-of-adhd-in-a-3-to-6-month-old Publisher: Pinnacle Blooms Network / Bharath Healthcare Laboratories Private Limited ADHD cannot be identified in a 3-to-6-month-old and there is no infant signs list to watch for. ADHD is a sustained pattern recognised only from the preschool years. At this age, track normal milestones — social smiles, eye tracking, head control, reaching — and see a clinician for any general developmental concern. *When you're already wondering about your tiny baby's future, even a quiet worry deserves a clear, kind answer — so let's start with the most reassuring truth.* ## In short ADHD cannot be identified in a 3-to-6-month-old, and there is no list of infant "ADHD signs" to watch for. ADHD ([ICD-11 6A05](/adhd)) describes a sustained pattern of inattention and hyperactivity-impulsivity that can only be meaningfully recognised in the preschool years and beyond, once a child is walking, talking and managing tasks. At this age, the kindest and most useful thing you can do is simply track healthy general development — and a wriggly, busy, alert baby is a wonderful sign, not a warning. ## What is actually worth watching at 3–6 months Rather than looking for ADHD, look for these reassuring developmental milestones: - **Social warmth** — smiling back at you, cooing, enjoying face-to-face play - **Following with eyes** — tracking your face or a toy as it moves - **Head control** — steadier head when held upright, beginning to push up on tummy - **Reaching and grasping** — swiping at toys, bringing hands to mouth - **Responding to sound** — turning toward your voice, calming to familiar sounds High activity, frequent movement and a short attention span are completely normal and healthy in babies — they are not early ADHD. ## When ADHD assessment becomes meaningful Concerns about attention, activity and impulsivity are usually first explored from around **age 4–6**, when behaviour can be compared with peers across settings such as home and preschool. If at any age your child loses skills they once had, isn't meeting milestones, or you simply feel something is different, a general developmental check is the right first step — never "wait and see" alone. ## The Pinnacle way Developmental measurement supports care planning; diagnosis requires an appropriately qualified healthcare professional., under the care of a qualified clinician — never from an online list. For now, a gentle [developmental check](/ask/what-is-the-abilityscore-and-how-is-it-calculated) gives you an objective baseline and peace of mind, and our [behaviour therapy](/behaviour-therapy) team is here whenever questions about attention arise in later years. You can read more about [ADHD](/adhd) and how it is recognised over time. ## Trusted sources Aligned with WHO ICD-11 (6A05 ADHD), CDC "Learn the Signs.
