Signs & concerns
What sensory milestones should a 3-to-6-month-old reach?
By 3 to 6 months, most babies track moving objects smoothly, turn towards voices and sounds, reach for and grasp toys they see, and explore textures with hands and mouth — signs that vision, hearing and touch are working together. These are a happy range, not a strict timetable.
Read the answer AnswerSensory milestones for your 3-to-6-month-old
By 3–6 months most babies smoothly track moving objects with their eyes, turn towards your voice and sounds, bring hands and toys to the mouth, and reach for things they see. These are gentle guides, not deadlines — every baby blooms on their own timeline. A check is wise if your baby doesn't react to sound or doesn't fix and follow with their eyes.
Read the answer AnswerWhat should a 3-to-6-month-old be able to do?
By 3 to 6 months most babies hold their head steady, push up in tummy time, reach for and grasp toys, roll over, laugh and coo back, and turn towards sounds and faces. These are typical ranges, not deadlines — a quick check helps if your baby misses several or loses a skill.
Read the answer AnswerSocial Milestones for a 3-to-6-Month-Old
Between 3 and 6 months, babies become social partners — smiling back, laughing, recognising familiar faces, and 'talking' in cooing back-and-forth turns. Babies vary in pace, so steady joyful progress matters more than any single day. If by 6 months there's little social smiling, eye contact or vocal turn-taking, a gentle developmental check is wise.
Read the answer AnswerWhat Social milestones should my 3-to-6-month-old have reached?
By 3 to 6 months most babies smile back, recognise familiar faces, enjoy watching people, laugh, and 'chat' in turn-taking coos. These are flexible guideposts, not a strict checklist. A gentle developmental check is wise if your baby isn't smiling back by 3 months or seems hard to engage by 6 months.
Read the answer AnswerWhen should I worry that my 3-to-6-month-old might have ADHD?
ADHD cannot be identified in a 3-to-6-month-old, and clinicians do not diagnose it this early — infant fidgetiness and short attention are normal. At this age, track ordinary milestones like smiling, babbling and head control instead, and route any general concern to a developmental check.
Read the answer AnswerAttachment Difficulties at 3–6 Months
At 3 to 6 months it is too early to identify Attachment Difficulties — this is never diagnosed in early infancy. What matters now is enjoying responsive, warm care and watching the everyday building blocks of connection: social smiling, eye contact, calming to your voice, and cooing turn-taking. If your baby consistently doesn't smile, make eye contact or settle, see a clinician for a general developmental check, not an attachment label. Only a Pinnacle clinician can assess.
Read the answer AnswerWhen to Worry About Auditory Processing at 3–6 Months
At 3–6 months it is far too early to identify Auditory Processing Difficulties — that describes how the brain interprets sound and only becomes meaningful after roughly age 6–7. What matters now is hearing: startling to loud sound, quietening to your voice, and turning towards sounds. A missed or flagged newborn hearing screen, or no response to sound, deserves a prompt hearing check, not therapy.
Read the answer AnswerWhen should I worry about autism in a 3-to-6-month-old?
At 3 to 6 months, autism cannot be diagnosed and there is no reliable signs list this young. Watch your baby's everyday social development — smiling, cooing, turning to sounds — and raise concerns with your paediatrician. Structured autism screening usually begins near 18 months; only a clinician can assess.
Read the answer AnswerWhen should I worry about Cerebral Palsy at 3–6 months?
At 3–6 months CP isn't diagnosed at home, but persistent stiff or floppy tone, poor head control, early strong hand preference or one-sided movement are reasons to ask for a developmental check. Worry is a reason to check, not a diagnosis — only a clinician can confirm.
Read the answer AnswerWhen should I worry about anxiety in my 3-6 month old?
A 3-to-6-month-old cannot have a diagnosable anxiety disorder — their brain has not yet developed the thinking and memory it requires. Crying, clinging and startling are normal, healthy signs of bonding and a working nervous system. Anxiety as a condition is considered only in older, preschool-and-beyond children. For now, focus on comfort and overall development; if anything worries you, a general developmental check with a clinician brings clarity. Only a Pinnacle clinician can assess — never an online form.
Read the answer AnswerWhen should I worry about apraxia in a 3-to-6-month-old?
Childhood Apraxia of Speech cannot be identified at 3–6 months — it only becomes meaningful once a child is attempting words, usually after 18 months to 2 years. At this age, watch and enjoy the early building blocks instead: cooing, babbling, smiling, eye contact and turning to sounds. If your baby isn't responding to sound, making any vocal sounds, or connecting socially, that warrants a prompt general developmental and hearing check — not because of apraxia, but for peace of mind. Only a Pinnacle clinician can assess, never an online form.
Read the answer AnswerWhen should I worry about epilepsy in my 3-to-6-month-old?
Epilepsy is a medical condition, so any suspected seizure in a 3-to-6-month-old needs a prompt doctor's visit, not a wait-and-watch approach. Most unusual baby movements are harmless, but clusters of sudden flexing or stiffening, unresponsive staring, or colour change need same-day medical review. Film the episode and seek a paediatrician or neurologist; only a clinician can diagnose.
Read the answer AnswerWhen should I worry about my 3–6 month old's sleep?
At 3–6 months, frequent night waking and uneven naps are normal as sleep cycles mature — not a sleep disorder. True worry signs are health-related: breathing pauses or snoring, poor weight gain, persistent inconsolable crying, or unusual floppiness and low alertness. These warrant a prompt paediatric review, not sleep training.
Read the answer AnswerWhen to worry about Conduct-Dissocial Disorder in a 3-to-6-month-old
A 3-to-6-month-old cannot have Conduct-Dissocial Disorder — this condition requires a sustained pattern of intentional rule-breaking that only becomes meaningful in older children and adolescents. At this age, crying and fussing are communication, not conduct. The right focus is healthy bonding and milestones like social smiling, eye contact and cooing. Only a Pinnacle clinician can assess development, never an online form.
Read the answer AnswerWhen to Worry About DCD in a 3-to-6-Month-Old
Developmental Coordination Disorder (ICD-11 6A04) is a disorder of learned motor skills and cannot be identified in a 3-to-6-month-old — there are no skilled movements to assess yet, and it is usually recognised only around school age. At this stage, simply track age-appropriate milestones like head control, reaching and emerging rolling, and raise persistent stiffness, floppiness or loss of a skill with your doctor. Any assessment or AbilityScore® is formed only at a Pinnacle centre under clinician care.
Read the answer AnswerWhen should I worry that my 3-to-6-month-old might have Developmental Language Disorder?
At 3 to 6 months it is too early to identify Developmental Language Disorder, because spoken language hasn't emerged yet. What matters now is pre-language communication — cooing, babbling, smiling back, and turning to your voice — and confirming your baby hears well. DLD becomes meaningful from around age 2 and beyond. Mention any hearing or sound-response concern promptly; only a Pinnacle clinician can assess, never an online form.
Read the answer AnswerWhen should I worry about Developmental Regression in my 3–6-month-old?
At 3–6 months, true developmental regression is uncommon — babies are mainly gaining skills, not yet showing the complex losses we call regression in older children. Worry promptly if your baby loses something they clearly had: head control, social smiles, tracking, cooing, or normal muscle tone. A real loss of established skills at this age is a medical matter — see your paediatrician promptly so any cause can be checked first.
Read the answer AnswerWhen to worry about Developmental Trauma at 3–6 months
At 3–6 months, Developmental Trauma cannot be diagnosed from a baby's fussiness or sleep — it describes the lasting impact of serious early adversity, not ordinary infancy. What matters now is the safety and warmth of caregiving, plus emerging comfort, social smiles and tracking. Persistent inability to be soothed, loss of responsiveness, or a history of real adversity warrants a general developmental and medical review focused on the parent–baby bond — never alarm or a label.
Read the answer AnswerWhen should I worry that my 3-to-6-month-old might have Down Syndrome?
Down syndrome is identified at or soon after birth via physical features and a confirming chromosome test — not first discovered at 3–6 months. If your baby was examined at birth with no concern, it is unlikely to surprise you now. At this age simply observe head control, tone, feeding and social smiling, and share questions with your paediatrician.
Read the answer AnswerWhen to worry about dyscalculia at 3–6 months
Dyscalculia is a maths learning difficulty that cannot be identified in a 3-to-6-month-old — number skills emerge only in the preschool and early-school years, with a meaningful question of dyscalculia usually arising around ages 7–8. At this age, simply enjoy and watch your baby's general development: smiling, tracking faces, turning to sound and steadier movement. Keep routine checks on track, and only a Pinnacle clinician can ever form an AbilityScore® or diagnosis.
Read the answer AnswerWhen to worry about dysgraphia in a 3-to-6-month-old
Dysgraphia (Written Expression Impairment, ICD-11 6A03.1) cannot be identified in a 3-to-6-month-old, because writing is a skill that only emerges years later, typically recognised from ages 6 to 8. At this age, simply nurture and observe the early building blocks — hand-eye coordination, grasping, head control and social smiling. Any genuine concern now belongs to general development, not dysgraphia, and a clinical AbilityScore® or diagnosis is formed only at a Pinnacle centre.
Read the answer AnswerWhen to worry about dyslexia in a 3–6 month-old
Dyslexia is a reading impairment that can only be identified once a child is learning to read, typically from age 6 to 8 — so there is nothing to worry about at 3 to 6 months and no infant signs of dyslexia exist. At this age, watch instead for responses to sound, cooing and babbling, eye contact and social smiles. If your baby does not react to sounds or your voice, seek a prompt hearing and communication check. Only a Pinnacle clinician can assess, never an online form.
Read the answer AnswerWhen to worry about EBD in a 3–6-month-old
At 3 to 6 months it is too early to label Emotional & Behavioural Difficulties — these patterns are recognised in older children, not young babies. What matters now is the foundation of connection: social smiles, calming when comforted, watching faces, cooing. If those are consistently absent or fading, seek a general developmental check rather than a behaviour-focused assessment.
