Signs & concerns
When to worry about feeding in a 3–6 month-old
Between 3 and 6 months, feeding is still settling and wide variation is normal. Worry — and seek a check — when feeding is consistently distressing, weight gain falters, or there is coughing, choking or colour change during feeds. Most causes are simple and treatable. Only a Pinnacle clinician can assess; never diagnose from a checklist.
Read the answer AnswerWhen to worry about FASD in a 3-to-6-month-old
FASD cannot be confirmed in a 3-to-6-month-old from a checklist; its learning and behaviour features emerge as a child grows. The most useful step now is to tell your paediatrician if there was any alcohol exposure in pregnancy, so your baby can be gently monitored. Observe growth, feeding and early milestones — and remember only a Pinnacle clinician can assess, never an online form.
Read the answer AnswerWhen should I worry about Fine Motor Delay at 3–6 months?
At 3–6 months, fine motor skills are only beginning, so true delay is rarely the right term this early. Look at direction of travel: hands opening from fists, reaching towards toys, hands meeting at the midline. Seek a friendly check if, by around 6 months, your baby isn't reaching or grasping at all, keeps fists tightly closed, or uses one side far less — not alarm, just a quick look.
Read the answer AnswerWhen should I worry about genetic syndromes at 3–6 months?
At 3–6 months, a single feature rarely signals a genetic syndrome — a pattern does: persistent low or high tone, poor feeding and slow growth, several distinctive physical features together, or steadily lagging milestones. Because syndromes are confirmed by medical examination and genetic testing, this is a doctor-first conversation. Early identification means an early plan, not just a label.
Read the answer AnswerWhen should I worry about Global Developmental Delay at 3-6 months?
At 3 to 6 months it is too early to diagnose Global Developmental Delay. Watch broad signals — head control, social smiling, reaching, responding to sound — and check in if a pattern persists or skills are lost. Only a clinician can assess; worry is a reason to screen, not a diagnosis.
Read the answer AnswerWhen should I worry about Gross Motor Delay at 3–6 months?
Between 3 and 6 months, head control, forearm push-ups, reaching and early rolling are the foundations to watch. One late skill is rarely worrying — babies vary. Check in with a clinician if several skills lag, head control isn't steady by around 4 months, tone seems very stiff or floppy, movement is markedly one-sided, or a skill is lost.
Read the answer AnswerWhen to worry about hearing impairment at 3–6 months
At 3–6 months, hearing is watched gently, not feared. Expect startle to loud sounds, calming to your voice, turning towards sound, and early cooing. A consistent absence — or NICU, prematurity, jaundice or family history — warrants a hearing check. Only a clinician can confirm.
Read the answer AnswerHypotonia at 3-6 Months: When Should I Worry?
Between 3 and 6 months, low muscle tone (hypotonia) is worth a prompt paediatric check — not panic — if your baby feels persistently floppy, has poor head control beyond about 4 months, slips through your hands when held upright, or tires easily at feeds. Low tone is a finding, not a diagnosis; early review usually brings reassurance, and a clinician can find any cause and start gentle support if needed.
Read the answer AnswerWhen to worry about Intellectual Disability at 3–6 months
At 3–6 months, Intellectual Disability cannot and should not be diagnosed — the abilities it describes haven't emerged yet. Instead, watch warm early milestones like social smiles, tracking faces and head control, and raise any concern at your routine paediatric visit. Only a Pinnacle clinician forms any assessment.
Read the answer AnswerWhen to worry about Motor Planning Difficulties at 3–6 months
Motor planning difficulties cannot be meaningfully identified at 3 to 6 months — true motor planning only emerges later, once a baby reaches, sits and explores with intention. At this age, watch the foundations of movement instead: tone, head control, hands to midline and early reaching. Genuine motor red flags such as persistent stiffness, floppiness, strong head lag or marked one-sidedness warrant a prompt developmental check, but most babies simply need more time and a clinician's reassuring eye.
Read the answer AnswerWhen should I worry about a non-verbal presentation at 3–6 months?
At 3 to 6 months it is too early to identify a non-verbal or minimally verbal presentation, because spoken words are not yet a milestone. What matters now is early connection — social smiling, cooing, eye contact and turning to sound. Concern about limited spoken language becomes meaningful much later, well into the second year. Enjoy and gently observe, and raise any hearing or responsiveness worry with your paediatrician.
Read the answer AnswerWhen should I worry about ODD in a 3-to-6-month-old?
Oppositional Defiant Disorder cannot and should not be identified in a 3-to-6-month-old — it needs a child old enough to understand rules and choices, usually not before the preschool years. A baby's crying, fussing or squirming is communication, not defiance. Watch instead for ordinary milestones — smiling, eye contact, cooing — and route any worry to a general developmental check. Only a Pinnacle clinician can assess, never an online form.
Read the answer AnswerWhen should I worry about toe-walking at 3-6 months?
At 3 to 6 months, persistent toe-walking is not a meaningful concern — toe-walking only appears after a child begins walking (usually 9–18 months). Pointed toes at this age reflect normal infant reflexes and tone. What matters now is head control, tummy time and even movement; raise persistent stiffness or floppiness with your doctor, and review toe-walking only once walking is well established.
Read the answer AnswerWhen to worry about prematurity-related developmental risk at 3–6 months
For a premature baby, always track milestones by corrected age (counted from the due date) until about two years. At 3–6 months corrected, the goal isn't diagnosis but gentle watching of early movement, looking and social connection. Persistent stiffness or floppiness, a tightly fisted or one-handed preference, no response to faces or sound, or no social smile deserves a prompt clinician check — but most early babies thrive with time and support.
Read the answer AnswerWhen should I worry about Rett Syndrome at 3–6 months?
Rett Syndrome is rarely identifiable at 3–6 months, because its hallmark is a later loss of skills after a period of normal early development — usually after 6–18 months. At this age, simply track ordinary milestones like eye contact, head control and babble, and seek prompt review if your baby ever goes backwards. A focused Rett assessment becomes meaningful later and is confirmed only by a clinician with genetic testing — never an online form.
Read the answer AnswerWhen to Worry About School Readiness at 3-6 Months
School readiness cannot be assessed in a 3-to-6-month-old — it becomes meaningful only from around age 3, near preschool. At this age, what matters are early foundations: smiling, cooing, tracking faces, head control and reaching. There are no school-readiness signs to fear now; if early milestones feel missing, a general developmental check brings reassurance.
Read the answer AnswerWhen to Worry About Selective Mutism at 3–6 Months
Selective Mutism cannot begin or be identified at 3 to 6 months. It is an anxiety-based condition affecting a child who can already speak but stays silent in specific settings — recognised typically around ages 3 to 5. At infancy, focus on warm early communication: cooing, social smiles, eye contact and emerging babble. Any worry about hearing or responsiveness deserves a gentle general developmental check, never a Selective Mutism label. Only a Pinnacle clinician can assess.
Read the answer AnswerWhen should I worry about self-regulation at 3–6 months?
At 3 to 6 months, self-regulation is only just beginning and develops through you — frequent crying and needing help to settle are normal, not a disorder. "Self-Regulation Difficulties" is not a diagnosis applied to young infants. Worth a gentle check: a baby consistently inconsolable over weeks, very stiff or floppy, or with little social smiling or response by around 4 months. The stance is reassurance and observation, not alarm.
Read the answer AnswerWhen to worry about feeding selectivity at 3–6 months
At 3–6 months there is no clinically meaningful diagnosis of Sensory-Based Feeding Selectivity — babies are still on milk and cannot yet choose between food textures or types, so true selectivity isn't possible. Focus instead on steady weight gain, wet nappies and a baby who feeds and settles well. Seek a prompt paediatric check for poor weight gain, choking or coughing at feeds, or persistent refusal — these point to feeding mechanics, not selectivity. Genuine feeding selectivity is considered only once a child eats solids and rejects whole food groups.
Read the answer AnswerWhen to worry about sensory differences in a 3-to-6-month-old
At 3–6 months, Sensory Processing Differences cannot be diagnosed — sensory systems are still maturing and big reactions are usually normal. Watch for persistent patterns in soothing, responding and connecting, and raise any concern at routine checks. Only a clinician gives clarity.
Read the answer AnswerSeparation Anxiety in a 3-to-6-Month-Old: When to Worry
At 3 to 6 months, Separation Anxiety Disorder is not a meaningful diagnosis — distress when you leave is a healthy, expected sign of bonding. Normal separation protest peaks around 8–18 months, and the disorder itself is only considered in pre-school or school-age children. Responsive comfort now builds secure attachment; only a Pinnacle clinician forms any assessment, never an online form.
Read the answer AnswerWhen to Worry About Social Communication at 3–6 Months
At 3 to 6 months it is far too early to identify Social Communication Difficulties — that label belongs to much later childhood. This age is about gently enjoying early connection: social smiles, eye contact and cooing. If these seem persistently absent over several weeks, the right step is a friendly general developmental check (and a hearing review), never alarm or labelling. Only a Pinnacle clinician can assess, never an online form.
Read the answer AnswerWhen to worry about SLD in a 3-to-6-month-old
Specific Learning Disability cannot be identified in a 3-to-6-month-old — it concerns reading, writing and maths, which only emerge with schooling around age 6–8. At this age, simply track ordinary milestones like smiling, following faces and babbling, and raise any general concern at routine check-ups.
Read the answer AnswerWhen should I worry that my 3-to-6-month-old might have Speech and Language Delay?
At 3 to 6 months it is too early to diagnose speech and language delay — words are months away. Enjoy and encourage cooing, smiling and babbling. The one thing worth checking promptly is hearing if your baby doesn't react to sound or your voice. Formal language assessment becomes meaningful nearer 18–24 months.
