At this age there is no meaningful test for autism, ADHD or learning differences; instead, a clinician simply watches how your baby is growing, moving, looking, listening and connecting. If your baby is meeting their everyday milestones and you have no specific concern, your regular paediatric reviews are usually enough. If something does feel different to you, a friendly developmental check brings reassurance and an early start if any support is helpful.\n\n## What is appropriate to observe at 3–6 months\nThis is a stage of lovely, observable change. Gentle things to enjoy and notice:\n- **Connection** — smiling back at you, watching faces, calming to your voice, beginning to coo and make sounds.\n- **Looking and listening** — following a moving toy with their eyes, turning toward sounds and voices.\n- **Movement** — steadier head control, pushing up on the tummy, reaching for and grasping objects, bringing hands to the mouth, and from around 4–6 months beginning to roll.\n- **Feeding and settling** — feeding comfortably and developing more settled sleep patterns.\n\nBabies vary, and milestones arrive across a range of weeks, not on a fixed day. A check at this age is observational and reassuring — never a label.\n\n## When a check is worthwhile sooner\nDo arrange a developmental check (and speak to your paediatrician) if you notice: no smiles or eye contact by around 3 months, not following objects or turning to sound, very stiff or very floppy posture, hands kept tightly fisted most of the time, not bringing hands together, or a loss of skills your baby once had. Any concern about hearing or vision deserves prompt review. Trusting your own instinct as a parent is always valid.\n\n## The Pinnacle way\nAbilityScore® is part of Pinnacle’s developmental assessment. Diagnosis, where needed, requires an appropriately qualified healthcare professional — never from an app, a checklist or an online form. At this age our role is gentle observation and reassurance, with an [early developmental check](/) and, where useful, a clinician-administered [AbilityScore® assessment](/ask/what-is-the-abilityscore-and-how-is-it-calculated) that tracks how your baby is growing across communication, movement and connection. If early support is ever helpful, our [early intervention programme](/early-intervention) is built around play and your bond with your baby.\n\n## Trusted sources\nAmerican Academy of Pediatrics (HealthyChildren.org) guidance on infant developmental milestones and well-baby visits; CDC milestone guidance for infants; WHO Nurturing Care framework for early childhood development.\n\n**Next step —** Want simple peace of mind about your baby's development?
