Signs & concerns
Global Developmental Delay at 9–12 months: when to worry
At 9 to 12 months it is too early to diagnose Global Developmental Delay, but a pattern of delay across two or more areas — or losing a skill — is worth a developmental screen. Worry is a reason to check, not a diagnosis. Only a Pinnacle clinician can assess your child.
Read the answer AnswerWhen to Worry About Gross Motor Delay at 9–12 Months
By 9 months most babies sit steadily; by 12 months most are crawling, pulling to stand or cruising. Check with a clinician if your baby cannot sit unsupported at 9 months, has no way of moving themselves at 12 months, cannot bear weight on their legs, feels stiff or floppy, or strongly favours one side. A single late skill is usually fine; a cluster, a one-sided pattern or a loss of skills deserves prompt review.
Read the answer AnswerWhen should I worry about hypotonia in my 9–12 month old?
By 9–12 months, gentle concern about low muscle tone is reasonable if your baby still feels floppy, isn't sitting steadily, can't bear weight on their legs, or has stalled in motor progress. Hypotonia describes how muscles feel rather than a single diagnosis. Any clear flag or stall warrants a prompt developmental check — early support helps muscles and movement flourish.
Read the answer AnswerWhen to worry about Intellectual Disability at 9–12 months
Intellectual Disability cannot be diagnosed at 9–12 months — development is too variable this early. Watch your baby's overall pattern of social, communication and motor milestones, keep up well-baby checks, and seek a general developmental screen if several areas consistently lag. A diagnosis is meaningful only later, and only a clinician can make it.
Read the answer AnswerWhen should I worry about Motor Planning Difficulties at 9–12 months?
At 9–12 months, specific Motor Planning Difficulties are too early to label — babies are still building the basic motor skills that planning later depends on. What matters now is the broad picture: reaching, sitting steadily, beginning to move across the floor, and comfortable muscle tone. Clear delay, strong early hand preference, or floppiness/stiffness warrants a prompt general developmental check, not alarm.
Read the answer AnswerNon-Verbal Signs at 9–12 Months
At 9 to 12 months it is too early to call a baby non-verbal — true words usually come after the first birthday. The real signs to watch are pre-verbal: babbling, gestures, eye contact, responding to their name and back-and-forth play. A general developmental check (and a hearing check) is worthwhile if these are clearly absent by around 12 months, or if any skill is lost.
Read the answer AnswerWhen Should I Worry About ODD in My 9–12-Month-Old?
Oppositional Defiant Disorder cannot and should not be identified at 9–12 months — it describes a pattern of deliberate defiance and argumentativeness that requires language and reasoning a baby hasn't developed, and is recognised only from around age 3. A strong-willed, protesting infant is showing healthy temperament. At this age, watch joyful milestones like babbling, responding to name and pointing instead, and raise any concerns at a routine developmental check. Only a Pinnacle clinician can assess — never an online form.
Read the answer AnswerWhen should I worry about toe-walking at 9–12 months?
At 9–12 months, occasional tiptoeing is normal exploration and not a reason to worry — persistent toe-walking can only be assessed once a child walks independently, usually after 12–18 months. What matters now is overall muscle tone and motor milestones, not toe posture. Mention any consistent leg stiffness to a clinician, and revisit if toe-walking persists past 18–24 months.
Read the answer AnswerWhen to worry about prematurity risk at 9–12 months
For a baby born preterm, always read milestones by corrected age (counted from the due date) until about two years — many "late" skills simply reflect those extra weeks of catching up. Bring a developmental check forward if, by corrected age, your 9–12-month-old isn't sitting steadily, isn't using both hands, shows little babbling or response to their name, or has lost a skill. This is monitoring, not alarm — early support works best when it begins early.
Read the answer AnswerWhen should I worry that my 9-to-12-month-old might have Rett Syndrome?
At 9–12 months it is usually too early to confirm Rett syndrome, whose hallmark loss of hand use typically appears between 12 and 18 months. What warrants prompt review now is any genuine loss of skills a baby once had, slowing head growth, or a drop in engagement — none of which confirms Rett syndrome, but all of which deserve a developmental check.
Read the answer AnswerWhen to Worry About School Readiness Gap at 9–12 Months
A School Readiness Gap cannot be identified in a 9-to-12-month-old — school-readiness skills build over the years before school and become relevant around ages 3 to 5. At this age, the right focus is ordinary infant milestones (babbling, sharing smiles, sitting, crawling) tracked through routine well-baby checks. Bring forward a general developmental check only if your baby loses a skill or shows little response to name or voice.
Read the answer AnswerWhen to Worry About Selective Mutism at 9–12 Months
Selective Mutism cannot be identified in a 9-to-12-month-old because it describes a child who can speak in some settings but not others — and spoken language hasn't developed yet at this age. There is nothing to worry about regarding this label now. Instead, observe healthy early communication: babbling, responding to name, gestures and warm back-and-forth. Selective Mutism is usually recognised from around age 3, often when starting nursery. Only a Pinnacle clinician can assess, never an online form.
Read the answer AnswerWhen should I worry about self-regulation at 9–12 months?
At 9 to 12 months self-regulation is still developing and babies depend on parents to co-regulate, so this is an age to observe and soothe, not to diagnose. Most fussiness, clinginess and broken sleep is typical. A gentle clinician check is wise only if intense distress is hard to soothe most days for several weeks, with few calm windows or little comfort-seeking.
Read the answer AnswerWhen should I worry about feeding selectivity at 9–12 months?
At 9–12 months, fussiness, gagging on new textures and many refusals before accepting a food are a normal part of learning to eat — not usually a diagnosis. Worry is warranted only when the pattern is persistent across weeks, narrows the diet, affects growth, or causes distress at every meal. Any coughing or choking during feeds needs prompt paediatric review. Only a Pinnacle clinician can assess, never an online form.
Read the answer AnswerWhen to Worry About Sensory Processing at 9–12 Months
At 9–12 months there is no diagnosable Sensory Processing Difference — babies are still building sensory wiring. Watch overall development warmly: connection, comfort, response to sound and movement. A persistent pattern, not one fussy day, prompts a gentle check. Only a clinician can assess.
Read the answer AnswerSeparation anxiety at 9–12 months: when to worry
At 9–12 months, distress at separation is a normal, expected milestone tied to object permanence and shows healthy attachment — not Separation Anxiety Disorder, which is a clinical label for much older children. There is almost nothing here to worry about as a disorder. A general developmental check (never an anxiety-disorder label) is wise only if your baby seems hard to comfort by anyone, flat, or shows little back-and-forth connection.
Read the answer AnswerWhen to Worry About Social Communication at 9–12 Months
At 9 to 12 months it is too early to label Social Communication Difficulties — this profile becomes meaningful only later. What is appropriate now is to gently watch the early building blocks of connection: eye contact, smiling back, responding to their name, shared attention, babbling and simple gestures. A consistent pattern of concern, or any loss of skills, deserves a calm word with your paediatrician — via a general developmental check, not a specific diagnosis. Only a Pinnacle clinician can assess.
Read the answer AnswerWhen to worry about SLD in a 9–12-month-old
Specific Learning Disability cannot be identified in a 9-to-12-month-old — it only becomes meaningful once school learning begins, around age 6–8. At this age, simply watch overall development: babbling, gestures, social play and movement. A developmental check brings reassurance now.
Read the answer AnswerWhen should I worry about speech delay at 9–12 months?
At 9 to 12 months it is too early to diagnose Speech and Language Delay — communication now is babble, gestures and shared attention, not words. Watch for absent babble, no gestures by 12 months, no response to sound, or loss of a skill, and have hearing checked. Worry is a reason to screen, not a diagnosis.
Read the answer AnswerWhen to Worry About Stereotyped Movements at 9–12 Months
Rhythmic repetitive movements — rocking, hand-flapping, head-rolling, gentle head-banging — are very common and usually normal self-soothing in babies aged 9–12 months. Stereotyped Movement Disorder (ICD-11 6A06) is rarely confirmed this early and matters only when movements are persistent, uninterruptible, harmful, or paired with loss of skills or reduced social connection. Observe and note rather than worry; raise concerns at a routine check, and seek prompt medical review for any sudden stiffening or jerking. Only a Pinnacle clinician can assess — never an online form.
Read the answer AnswerWhen should I worry that my 9-to-12-month-old might have Tourette Syndrome?
Tourette Syndrome cannot be identified in a 9-to-12-month-old — it is not clinically meaningful at this age, as tics typically begin around age 4–8 and must persist before assessment. Most baby twitches, shudders and repeated movements are normal nervous-system development. The real flags at this age are possible seizures or loss of skills, which warrant prompt medical review, not a Tourette worry.
Read the answer AnswerWhen to Worry About Visual Impairment at 9–12 Months
By 9–12 months babies should make eye contact, follow faces and moving objects, and reach accurately for toys. Worry signs include no eye contact, not following objects, wandering or misaligned eyes, a white or cloudy pupil reflection, or not reaching for things they can see. These warrant a prompt paediatric and eye check — vision develops fast in the first year, so early action protects it. Only a Pinnacle clinician can assess; never an online form.
Read the answer AnswerWhen should I worry my newborn might have ADHD?
ADHD cannot be identified in a newborn — attention and activity regulation have not developed yet, and every newborn is wakeful and wriggly. ADHD is only recognised in later childhood. For now, focus on milestones, and see a clinician for any general developmental worry.
Read the answer AnswerWhen should I worry about Attachment Difficulties in my newborn?
You cannot diagnose Attachment Difficulties in a newborn, and there is nothing to "watch for" at this age. The early months are when you build attachment through responsive care, not test for it. Genuine attachment concerns are only meaningful in older infants after disrupted care, and only a Pinnacle clinician can assess — never an online form. Focus now on connection and on supporting yourself as a parent.
